• Windows 7 loses correct time zone upon reboot

  - by Android Eve

  I have a standard PC running Windows 7 Ultimate (64-bit). For some reason, it refuses to keep the correct time zone (the BIOS battery is OK) when restarted. Note (1): The Time zone is correct. The "Internet Time" tab also shows "this computer is set to automatically synchronize with 'time.windows.com'. When I click the 'Change settings...' button, the 'Synchronize with an Internet time server' checkbox is checked. Still, upon reboot, the time is skewed by 6 hours... and doesn't correct itself even after waiting hours for this "automatically synchronize" to occur. Note (2): The BIOS time is set to local (i.e. not UTC). When I restart Windows 7 without booting to the other OS installed in dual-boot config (Ubuntu Linux), it seems to correctly remember the time. This may explain immediate time upon reboot, but it doesn't explain why Windows 7 won't automatically 'Synchronize with an Internet time server' even after an hour. Why is this happening and how do I correct this?

• Very Slow DSL (ethernet) speed

  - by Abhijit

  I 'was' on opensuse 12.2 when my dsl speed was normal. Yesterday I switched from opensuse to ubuntu 12.04 and speed decreased. It came to range of 7-10-13-20-25-kbps. Then I switch to linux mint, and then to fedora. Still slow speed. When I was in ubuntu I disabled ipv6 but still no luck. Now I am in fedora but this time with DIFFERENT ISP. And still I am getting very slow sped. So my guess is this is nothing to do with os. What can be wrong? Is this problem of NIC? Does NIC speed decreases over time? Does NIC life ends over time as with keyboard or mouse? Help please All the os I used are 64 bit and my laptop is Compaq Presario A965Tu Intel Centrino DUal Core. Interesting thing to notice is I get normal speed while downloading torrent inside torrent client softwares. This slow speed issue applied to download from any web browser or installing software using terminal.

• Monitor displays at 1024x768; scrolls screen for higher resolutions

  - by Matt

  I have a dual monitor setup. Normally, they both display at 1680x1050. They have been setup this way for about a year. I'm using Windows XP Professional 2003 x64 SP2. Today, out of nowhere, one of the monitors kicked back to a lower resolution. I was not playing with any configuration at the time.. in fact all I had done was close a window (maybe a browser). But the thing is that the resolution is still preserved partially by the fact that the screen will scroll when you move the mouse. So it's like looking through a 1024x768 window into a 1680x1050 world. The monitor itself does not appear to be damaged, because I also have it connected to my netbook (via KVM) and higher resolutions work fine. I tried uninstalling/reinstalling the drivers to no avail. System restore doesn't help either. I'm unsure of the exact ATI card I'm using.. Device Manager lists it as "Radeon X300/X550/X1050". There is no Catalyst Control Center software installed. I tried to install it, but there doesn't seem to be a way to install it by itself ... it forces you to install another driver, which breaks both of my displays, forcing me to go into safe mode and run system restore again. Any ideas? Thanks

• KeePass lost password and/or corruption due to Dropbox/KeePassX

  - by GummiV

  I started using Keepass about a month ago to hold my passwords and online accounts info. Everything was stored in a single .kdb file, only protected with a password. I'm using Windows 7. Now Keepass can't open my .kdb file with the error "Invalid/wrong key". I'm fairly confident I have the right password. Altough I might have mixed up a few letters I've tried about two dozen different combinations to minimize that possibility - but can't rule it out though. My guess is however that the .kdb file got corrupted, either due to Dropbox syncing (only using it on one computer though) or because I edited the file using KeePassX on Ubuntu (dual boot on the same computer, accessing a mounted Win7 NTFS partition), or possibly a combination of both. I have tried restoring older versions(even the original one) from Dropbox and trying out all possible passwords without any luck. (which does seem to rule out KeePassX as the culprit, since oldest copies are before I edited the file from Ubuntu) I have tried opening the file with the "Repair KeePass Database file" which always gives the "0xA Invalid/corrupt file structure" (the same error for when a wrong password is typed). I was wondering if there was any way for me to salvage my hard-gathered data. I know generally that brute force cracking is not feasible, but since I can remember probably more than half of the usernames/passwords, any maybe the fact that one of them does come up fairly often (my go-to pass for trivial stuff), that might simplify the brute force process to a doable time frame. Maybe the brute-force thing might incorporate the fact that I know the password length and what characters it's made from. (If we assume corruption, not a password-blackout on my part) I could do some programming if there are any libraries or routines that I could use. Other people seem to have had a similar probem http://forums.dropbox.com/topic.php?id=6199 http://forums.dropbox.com/topic.php?id=9139 http://www.keepassx.org/forum/viewtopic.php?t=1967&f=1 So hopefully this question will become a suitible resource for people when searching the web. Feel free to tell me if you think this should rather be a community wiki.

• Windows recovery partition with GRUB2

  - by Actorclavilis

  So I recently got a new Toshiba laptop and installed Ubuntu 12.04 on it. Since it is a "Windows 7 Enabled" machine or some other proprietary nonsense like that, a few hardware features are designed only to work with W7. Eventually I found a way to enable these hardware functions by booting into the W7 recovery disc; however, they sporadically stop working. I'm moderately surprised that I was able to get anything to work at all, so I don't especially want to spend more time fixing the problems in a different fashion. Now I don't actually own the recovery disc; it's my father's. Since it's a pain to have to go asking for the disc every time the features stop working, I made an image of the disc and was hoping to make a 'recovery' partition like some computers have. However, unetbootin and GRUB2 both want a kernel and initrd to point to on startup, and something like set root=(hd0,1) loopback lo /w7r.iso set root=(lo) chainloader +1 in the spirit of the makeactive/ chainloader +1 commands that I used to use to dual-boot Linux and Windows simply gives me a file-not-found error. My question, therefore, is: Is it possible to, having written a Windows iso to a partition (such as with dd if=w7r.iso of=/dev/sda4) to a partition, convince GRUB2 to boot from it? Thanks in advance.

• GA 8KNXP Rev1.0: 4GB installed, only 3.5 recognized by BIOS

  - by hurikhan77

  I've installed 2x 1 GB and 4x 512 MB memory into my GA-8KNXP system which would sum up to 4GB. The specs from the manual say: Maximum memory support: 4GB. If all six slots are utilized, slot 5+6 may only equipped with single-sided RAM modules. And so I did. Anyway: The BIOS counts up to 3.5 GB and finishes there. Also my linux system reports only 3.5 GB of memory although 4 GB memory support is activated in the kernel. So I suppose this is a memory mapping issue or a hardware issue. I've tried removing only on of the 512 MB memory modules leaving 5 modules in place. But that just stopped the system from powering on correctly (screen stays black although fans and leds come to live). Dual Channel was detected and enabled so the system technically found all 6 modules. "dmidecode" in linux reports only memory in slots 1 to 4 and ignores slots 5+6, so it only detects 3 GB of memory. It also says the system would support up to 16 GB of memory with 4 GB modules per slot. I think technically the chipset should be able to offer and utilize the complete 4 GB memory range. Any clues what else I could check? Or do I have just to live with 0.5 GB wasted memory?

• Ubuntu 12.10, Unity, AMD 12.11 beta drivers, AMD APP SDK 2.7 and OpenCL detection of multiple gpus

  - by junkie

  I'm using Ubuntu 12.10, AMD 12.11 beta drivers, AMD APP SDK 2.7 and OpenCL. I have three amd radeon 7990s plugged in each of which are a dual 7970 so I have six gpus altogether. I plan to go up to eight in a few days. Windows couldn't use even 4 but linux works fine with 6 so far. The strange thing is that the six gpus are only detected by OpenCL in unity (the ubuntu default window manager). If I switch to e17, blackbox or fluxbox or anything else for that matter OpenCL only detects one. I'm using a simple OpenCL program to list all devices to check. I've also checked the output of aticonfig --list-adapters, fglxinfo and clinfo. The first two always show six in all window managers wheras clinfo shows 6 in unity but 1 gpu in all other WMs. I'm also using an X config generated by aticonfig --initial -f --adapter=all. I'm also only using one monitor. I've also checked using lsmod that the fglrx module is loaded in all WMs. So I have two questions. Why does OpenCL see six gpus only in unity? How can I enable six gpus on other lightweight WMs? Basically I'm getting at what determines how many gpus the OpenCL runtime sees? Thanks.

• Am I getting the right memory for my motherboard?

  - by Daniel Carvalho

  Hi technophiles; I have a Gigabyte GA-EP45-DS motherboard. Also, the memory that came with my computer was two Transcend aXe RAM 1066MHZ 1GB modules. The thing is, I noticed that my motherboard has "DDR2 1200" written on it. This concerns me, have I bought slower memory than my computer is supposed to have ideally? Now, I'm not super concerned at a granular level about the best optimal RAM with the best CAS latency etc... but I do hope at least that I've got the right speed. Now, as far as I know, there is no such thing as ram at 1200MHZ? Am I right? You see, because I'm thinking of getting more RAM now, before I can't find the same type or speed any-more and just want to make sure it's the right thing. Furthermore, if the memory is slower than what I should be getting for my motherboard, what RAM should I be getting, and will that new RAM play nice with my old RAM? If I get new RAM at a different speed, would it be better / more beneficial performance-wise to omit the old RAM because of how the whole DUAL channel RAM thing works? I'm not too clued up on this area. Thanks chiefs.

• How do I install a different OS on a Compaq Presario cq56 with preinstalled SuSE 11?

  - by McCoy

  Thing is, I don't have a clue of Linux systems, I usually use WinXP. Bought a notebook with SuSE 11 on it, because I have my XP licence and thought I could install that if I found the chipset drivers for the hardware (which I'm not completely sure I have the right versions of). Then I thought I'd give it a shot with the SuSE, looked nice enough. But I can't get my external hd to work (tried force mount) and the banshee doesn't do anything like playing video. Since that is one of the two main purposes of this notebook, I need to get that to work. Tried downloading VLC player, but that only works with SuSE 11.1 upwards. So I downloaded a SuSE 11.3 and burned the iso. But surprise, no way the notebook would boot from cd. Same with the XP cd (considered setting up a dual boot). And no, I can't get to BIOS to reset to default, either. So I can basically do nothing else than going online with this thing and that's not enough for me (gamer in withdrawal, yikes!). I need at least to get to my firefox profile on the external hd and be able to watch video. Can somebody please help me? I think at this point I'd prefer to install XP and MAYBE the SuSE 11.3 after that. I'm not a native speaker, so please speak plainly, thanks. :) Edit: if this is impossible, could someone please help me with the external hd mount and video playback? Edit: Found out how to boot from cd by now. But still no XP, because I get bluescreen after bluescreen while setup is loading files. I guess it's the missing SATA drivers...

• Power issues Foxconn Barebones kit

  - by alpha1

  I have a Foxconn R20D2 bought about a year and a half ago. It ran fine for a while and then around last summer it started having power issues. I chalked it up to changes in electric current due to the overwhelmed grid when people turn on their AC units, but this problem has stayed for all year, shutting off randomly, shutting off when i turn on a vacuum and similar problems. Now that its summer again, the box basically sits there all day cycling itself, and now has gotten to the point it tried to boot and after 3 seconds, fails, shuts off and tried again. I know its power related, it runs opensuse linux and there are never any shutdown logs or anything of that sort. As the weather got hotter i noticed it happening more and more, and it most often happened in the morning, i presume as people woke up and turn on the AC. The power supply is a Chennel well technology co LTD model DSL-150. 150W max output. Its an intel atom dual core, with 2 sata drives, no CD/floppy etc, recently upgrades from 2 to 4gb of ram. It runs at 104 degrees Fahrenheit all the time almost. Any way i can test the power supply or anything else to try to fix it? Im a software guy, not hardware so im at a complete loss here, thanks for all assistance you can provide! EDIT: The switch on the back that says 230 or 115 is set to 230. If im in the USA, could that be causing the problems?

• Proxmox drbd configuration split brain [on hold]

  - by AudioDan

  I am planning a proxmox HA configuration with two Dell R710 machines (dual 6 core processors in each) with enterprise level drive raid arrays. I would be using DRBD with a quorum disk on a third machine. I would dedicate two 1GB nics on each server to the DRBD communications. We would have approximately 12 to 14 Virtual Machines running on this pair of servers. The proxmox manual recommends creating two DRBD resources - one for the Virtual Machines that normally run on ServerA and one for the Virtual Machines that normally run on ServerB. This is because of the Primary/Primary state in which this configuration runs. If both servers have VMs talking to the same DRBD resource and a split brain situation occurs, there is potential for data corruption that must be resolved. While I understand it would take more effort to create new virtual machines, can anybody foresee any potential problems with running a separate DRBD resource for each VM instead? Does anyone have experience running a setup that way and has it worked well? It seems to me that would allow more flexibility in moving machines back and forth.

• Ubuntu 10.10 - PC shutdown before boot shortly after BIOS loads

  - by clem

  Since installing Ubuntu 10.10 from Karmic I've started getting problems with starting up the PC. I've done a complete wipe (Boot and Nuke) of the hard drive and reinstalled Ubuntu 10.10 but the problem still occurs. There is no dual boot on the PC, just Ubuntu. Here is the problem: Each morning, when I turn the PC on from being off overnight, the PC starts up and loads the BIOS. I get the following message Verifying DMI Pool Data... K8 NPT Data Change...Update New Data to DMI!....... Then poof the computer shuts off. However, after switching the computer back on around 6 or 7 times after it's turned itself off, it will eventually boot up without any problem. Also, once up and running for a while, I can shutdown and restart the PC first time, without any issues. I have also noticed a problem with the USB mouse being recognised and once I finally get the computer booted up, I need to unplug and then plug the mouse back in to get it working. I've opened the PC up and checked the connections (cables, cards and memory) and it all seems fine. The main issue with troubleshooting this problem is I cannot test any suggestions or fixes until the next morning because once the computer is up and running it will remain so! I do not leave the computer on overnight to save energy. So.. Is this a hardware / boot software issue? This is a very odd problem and I have googled to no avail. Any suggestions?

• Linux Live CD only works when Windows is in Legacy mode?

  - by Vee

  I have asked a similar question before and no one was able to help me but I think it was because I wasn't phrasing it properly. This is a better restatement of the question. I have Windows 8 and Linux Mint dual booted on my pc. When I tried to boot the Linux from a CD ROM only, it would give me the following error: error: failure reading sector 0x0 from 'hd1' error: you need to load the kernel first. Press any key to continue... The Linux Mint works fine but otherwise, but it gives this error when I try to boot from CD. The boot Linux from CD only worked when I changed the Windows to Legacy mode in the BIOS settings. When I changed it back to UEFI, it would give the same error. Why is this? How can I fix it? I am somewhat new so is there anything else I should know about all of this? NOTE: I changed the Linux into UEFI mode using boot-repair but that still did not solve the problem when I tried to boot from CD ROM.

• Relaying to tech "support" that computer is actually broken.

  - by Sion

  First some background: I have a Dell Inspiron 15R M050, it is still under the Dell limited warranty and the Best Buy Extended warranty. I am currently dual booting Debian Squeeze and Windows 7, the only reason I go into Windows is to play video games specifically steam games. Issue: When I play my games in Windows I am capable of playing for anywhere from 5 minutes to 2 hours before I suffer a hard-lock. I cannot alt-tab, ctrl-alt-delete, ctrl-shift-escape do anything for 2-3 minutes. After this hard-lock period everything runs fine, I can continue the game for probably another hour at least before I suffer another lock. Games: Borderlands, Splinter Cell: Chaos Theory, Starcraft 2, Garrys Mod What I have tried: Running the diagnostic suite in the dell bios, restoring the OEM Windows recovery partition on the HD, fresh installing Windows 7 Professional, updating BIOS, Calling tech support and having them run a software Hardware Diagnostics suite. The question: I think from the research that I have performed that it might be a lack of thermal paste on the CPU, would I be able to go to Best Buy and have them do a hardware diagnostic from the hardware level then have them be able to tell Dell that there is a hardware issue? Or would there be a different problem?

• Intel Ethernet Bottlenecking Internet?

  - by Donald Darma

  I'm having trouble with my internet speeds. So I just recent build a pc and everything is fine. I installed the Intel drivers and connected to the internet. It connects but I'm only half the speed I should be getting. My normal speed is 20mbps but speedtest.net is only showing 10. It can't be my ISP (which is TWC if anyone is asking) because my other devices like my laptop and my smartphone are showing 20 down. Heres my system: CPU: i5 4430 HSF: Stock cooler Mobo: Gigabyte Z87MX-D3H GPU: x2 MSI R7950-3GD5/OC BE RAM: Crucial Ballistix Tactical Tracer 8GB dual channel PSU: Silencer High Performance Power Supply 750 Watt 80+ (It's a subdivision of OCZ) HDD: Seagate Barracuda 7200RPM 3TB SSD: Samsung 840 Evo 120 GB Case: Corsair Obsidian 350D Edit: I am using the stock adapter that is on the motherboard. I know for a fact that the cable is good because I used it on my laptop and it ran fine. Its a CAT5E cable. I also ran IPERF and its giving me the same results, 10 mbps.

• How can I setup a Proxy I can sniff traffic from using an ESX vswitch in promiscuous mode?

  - by sandroid

  I have a pretty specific requirement, detailed below. Here's what I'm not looking for help for, to keep things tidy and on topic: How to configure a standard proxy Any ESX setup required to facilitate traffic sniffing How to sniff traffic Any changes in design (my scope limits me) I need to setup a test environment for a network-sniffing based HTTP app monitoring tool, and I need to troubleshoot a client issue but he only has a prod network, so making changes to the config on client's system "just to try" is costly. The goal here is to create a similar system in my lab, and hit the client's webapp and redirect my traffic - using a proxy - into the lab environment. The reason I want to use a proxy is so that only this specific traffic is redirected for all to see, and not all my web traffic (like my visits to serverfault :P). Everything will run inside an ESX 4.1 machine. In there, there is a traffic collection vswitch in promiscuous mode that is not on the local network for security reasons. The VM containing our listening agent is connected to this vswitch. On the same ESX host, I will setup a basic linux server and install a proxy (either apache + mod_proxy or squid, doesn't matter). I'm looking for ideas on how to deploy this for my needs so I can then figure out how to set it up accordingly. Some ideas I've had were to setup two proxies, and have them talk to eachother through this vswitch in promiscuous mode, but it seems like alot of work. Another idea is a dual-homed proxy, but I've never seen/done that before so I'm not sure how doable it is for what I'd like. I am OK with setting up a second vswitch in promiscuous mode to facilitate this if need be, but I cannot put the vswitch on the lan (which is used so my browser would communicate with the proxy) in promiscuous mode. Any ideas are welcome.

• How can I remotely display images on my computer?

  - by Jakob

  What I Have: A laptop booted with Ubuntu and a stationary computer dual-booted with Ubuntu and Vista, both connected through a wireless ad-hoc network. What I Want: I want a way to display images in fullscreen on my stationary, using my laptop as a "remote control". I want to be able to choose another picture at any time and have my stationary computer remain in fullscreen mode at all times. Preferably, I should also be able to display just an empty (black) screen. How can I arrange for this? What I Have Tried: I have tried simply SSH:ing into my stationary computer and opening the image files using an image viewer, but all of the ones that I have tried (Eye of Gnome, Mirage, Gwenview, and others) open a new window for every new image. I don't know how to force them into using a single instance. I have tried using the VLC remote control command line interface, but apart from seeming somewhat unreliable (exiting with segmentation faults at one point), it also displays some images with a green border and forces me to pause playback in order for the image to remain on screen. Bonus Question: In my final setup, I also need to play music through my stationary computer's speaker and have the ability to switch to another track at any point, like with the images. Preferably, I would like to control the images and the audio through the same interface. How can I best achieve this?

• Windows 8 Fails to install with corrupted graphics

  - by Andy

  I am trying to install Windows 8 Pro Upgrade via the download method on an older PC (07-08). It is a Dell Dimension E521 but it has been upgraded with a 3.0 Ghz Dual Core AMD Processor, 120 GB SSD, and 4 GB of RAM. The Windows 8 upgrade assistant did not detect any issues or concerns with upgrading other than I don't have DVD software installed. The system install Windows 8 but on the first boot, corrupt graphics are present. Eventually, the monitor will go into sleep mode and then roll back to Windows 7 Pro X64 which runs fine. I wouldn't be upset over not being able to install Windows 8, but I already paid for the software since I thought there would be no issues upgrading. The Graphics card in the system is the Geforce 7300LE and it has the latest NVidia drivers for Windows 7 loaded. I saw this solution which is similar to my problem: Corrupt graphics during Windows 8 installation However, I have downloaded Windows 8 and I am not sure how to go about modifying the install that resides somewhere on the hard drive. Thanks in advance for any assistance.

• A router that supports connecting with 2 different wifi networks

  - by Allan Deamon

  I Have the following setup in one place: We have a small local ISP through wireless. I have a external parabolic antenna, connected to a external usb wifi radio, connected through USB to a desktop old PC. The pc connects do the ISP wiki network, then do a Dial Up (PPPoE) connection through the this wifi setup. This will expand with others mobiles devices to be used. When I need, I take my home wireless router and connect though Ethernet in the PC, which is shares the internet. The problem is that the PC must be always ON and working. I would like to buy a wireless router which could be an AP to the mobile devices, notebooks, etc, as also could connect to the ISP Wifi/PPPoE network. So, this device must: Have one radio with detachable antenna to connect to the external antenna. It must connect as client to a network and then dial up the PPP Have another radio serving as AP (infrastructure) to the local place This can't be very expensive. I found a candidate: ( http://www.tp-link.com/en/products/details/?categoryid=1682&model=TL-WR2543ND ) It have 3 deatachable antennas, working with dual band. Officially, his firmware doesn't support it. My supposition: If internally there is 3 or 2 distinct wlan ports (like wlan0, wlan1), and there is support, i could use a OpenWRT, DD-WRT or Tomato to make this works. It also have 1 USB port, which I cold use to connect my actual USB Wifi card on it instead to the old PC. Another alternative, is a router that can do this out of box, with the original firmware. But I don't think this is a easy thing to find.

• Software raid 0 with six disks performance

  - by user134880

  I have some problems with disk performance. I have 6 x WD 500Gb RE4 disks. Each disk gives 135Mb/sec throughput. All measurements are made with hdparm with options "-tT" (I know that it is just synthetic test, but I need some start point to make measurements). I have controller with Sil3124 x 4 ports PCI Express 1x So... RAID0 on controller with 2 disks gives 200Mb/s - ok, pcie limit. RAID0 on motherboard with 2 disks gives 270Mb/s - niceeee :) RAID0 on contorller with 4 disks gives 200Mb/s - ok, pcie limit. RAID0 on controller with 4 disks + 1 disks on motherboard = 340Mb/s ... :( RAID0 on controller with 4 disks + 2 disks on motherboard = 300Mb/s .... why? Any ideas? Maybe need more cpu power? Now there is Pentium D Dual core 2.8Ghz, 4Gb RAM. It is dedicated box for storage.. no other activity.

• Installing Ubuntu guest crashes Hyper-V host

  - by Grant

  I have a weird problem that I don't even know where to begin diagnosing. Trying to install Ubuntu to a VM locks up the host system! My setup is: Dell R715 server, dual 16 core AMD opteron processors, 96GB RAM Dell MD3600f SAN Server 2008 R2 Datacenter System Center VMM 2012 There are 5 windows virtual machines running that have had no problems. This is the first linux VM I've tried to create. I setup a VM through virtual machine manager, set the CD drive to a Ubuntu 12.04 server x64 iso, and started it up. It boots up the normal ubuntu install menu, but the second I hit enter on "Install Ubuntu Server", I get disconnected. The HOST machine stops responding to pings. So do all virtual machines on it. It locks up entirely - keyboard on the host won't work, mouse won't move, numlock light won't change. There's no blue screen - the host is sitting at the login screen completely unresponsive. I can't find any relevant logs in event viewer after rebooting. What could cause the host machine to freeze like that? It's not a one time occurrence - it happens every time at the exact same point. Thank god this server isn't in production yet!

• How to verify power provided to processors is clean

  - by GregC

  Once in a blue moon, I am seeing a blue screen of death on a shiny new Dell R7610 with a single 1100 Watt Dell-provided power supply on a beefy UPS. BCode is 101 (A clock interrupt was not received...), which some say is caused by under-volting a CPU. Naturally, I would have to contact Dell support, and their natural reaction would be to replace a motherboard, a power supply, or CPU, or a mixture of the above components. In synthetic benchmarks, system memory and CPU, as well as graphics memory and CPU perform admirably, staying up for hours and days. My questions are: Is power supply good enough for the application? Does it provide clean enough power to VRMs on the motherboard? Are VRMs good enough for dual Xeon E5-2665? Does C-states logic work correctly? Is there sufficient current provided to PCIe peripherals, such as disk controllers? P.S. Recently, I've gone through the ordeal with HP. They were nice and professional about it, but root cause was not established, and the HP machine still is less than 100%, giving me a blue screen of death once in a couple of months. Here's what quick web-searching turns up: http://www.sevenforums.com/bsod-help-support/35427-win-7-clock-interrupt-bsod-101-error.html#post356791 It appears Dell has addressed the above issue by clocking PCIe bus down to 5GT/sec in A03 BIOS. My disk controllers support PCIe 3.0, meaning that I would have to re-validate stability. Early testing shows improvements. Further testing shows significant decrease in performance on each of the x16 slots with Dell R7610 with A03 BIOS. But now it's running stable. HP machine has received a microcode update in September 2013 SUM (July BIOS) that makes it stable.

• sudo fdisk in a live session does not show all hard drives

  - by cornbread

  I am having Grub2 issues in my Ubuntu 10.04 dual boot, 2 hard drive system. So I am attempting to follow the standard grub2 reinstallation guide (cant post link because of spam filters allowing only one... ?_?) Don't know if this is the root of my problem, but my speedy internal HD with my OS on it is not showing up anywhere in a live session. Not in nautilus, behind fdisk.... no where. When I can get the main system to boot, there is no issue seeing all available partitions. But the live session sees only the 1TB internal media/backup hard drive. I need access to the other hard drive and it's partitions to finish the grub2 re-installation but I am not sure anymore that is the underlying issue. Anyone have experience with this? The issue I have identified as a grub2 issue is fully described here. SandPvvr describes it exactly. Some notes: I do not see the grub2 menu for my os's holding down the shift key after my bios screen works maybe 10% of the time Not related to reinstalling a windows os. havent been touched in a year do some web development. issue may have started when I was playing with ruby and django. not sure on this. Could a dev environment do this? fdisk in live session ubuntu@ubuntu:~$ sudo fdisk -l Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0001d518 Device Boot Start End Blocks Id System /dev/sdb2 1 121601 976759939 5 Extended /dev/sdb5 487 110765 885816036 83 Linux /dev/sdb6 110766 121601 87040138+ b W95 FAT32 /dev/sdb7 1 486 3903700+ 82 Linux swap / Solaris Partition table entries are not in disk order

• How far should we take the N+N redundancy craziness ?

  - by Brann

  The industry standard when it comes from redundancy is quite high, to say the least. To illustrate my point, here is my current setup (I'm running a financial service). Each server has a RAID array in case something goes wrong on one hard drive .... and in case something goes wrong on the server, it's mirrored by another spare identical server ... and both server cannot go down at the same time, because I've got redundant power, and redundant network connectivity, etc ... and my hosting center itself has dual electricity connections to two different energy providers, and redundant network connectivity, and redundant toilets in case the two security guards (sorry, four) needs to use it at the same time ... and in case something goes wrong anyway (a nuclear nuke? can't think of anything else), I've got another identical hosting facility in another country with the exact same setup. Cost of reputational damage if down = very high Probability of a hardware failure with my setup : <<1% Probability of a hardware failure with a less paranoiac setup : <<1% ASWELL Probability of a software failure in our application code : 1% (if your software is never down because of bugs, then I suggest you doublecheck your reporting/monitoring system is not down. Even SQLServer - which is arguably developed and tested by clever people with a strong methodology - is sometimes down) In other words, I feel like I could host a cheap laptop in my mother's flat, and the human/software problems would still be my higher risk. Of course, there are other things to take into consideration such as : scalability data security the clients expectations that you meet the industry standard But still, hosting two servers in two different data centers (without extra spare servers, nor doubled network equipment apart from the one provided by my hosting facility) would provide me with the scalability and the physical security I need. I feel like we're reaching a point where redundancy is just a communcation tool. Honestly, what's the difference between a 99.999% uptime and a 99.9999% uptime when you know you'll be down 1% of the time because of software bugs ? How far do you push your redundancy crazyness ?

• Fedora installed in Legacy mode, how to make it work in UEFI?

  - by TryntaLearn

  I am trying to install a linux distribution on my new laptop. It's an MSI GE40 which comes preinstalled with windows 8. It's a UEFI machine. I have tried installing Ubuntu and Fedora with limited success. I've tried: running it in UEFI, UEFI with CSM mode, with secureboot enabled, ... with secureboot disabeled, ... with secureboot enabled but in user mode. I have had no success with any of these methods. With Ubuntu the grub loader shows up, but when I pick 'try ubuntu', or 'install ubuntu', it's just a blank screen(I've been using liveusb's btw). With Fedora, it'll show me the next screen on which it says 'binary authorised by vendor certificate' or 'Secure boot not enabled' and then stop doing anything. The closest thing to success I reached was switching to legacy mode to install Ubuntu, in which case I was able to get to the ubunutu installer but it wouldn't recognize windows 8 on my computer, so instead of continuing on I rebooted, and removed the USB pendrive to find my computer couldn't find windows 8. After a little dicking about I got it to find windows 8 again. Any ideas on how I should go about trying to install a distro on my computer? UPDATE:- So I ended up installing fedora using Legacy mode. To use both it and Windows at boot, I manually enter automatic repair so I can get to my UEFI settings and switch boot mode to UEFI to boot windows 8. I guess my question needs to be modified as to how do I get all of this to work in UEFI mode, so I can dual boot via selection through a bootloader, and not by repeatedly switching boot mode.
