  • How to make a pxe bootable 10MegaByte or larger dos image?

    - by rjt
    Would like to make a "massive" DOS floppy disk image, say 10MegaBytes or more containing all the firmware updates i need for any system, harddrive, BIOS. i do not need the DOS image to be networkable as everything will be on the PXE booted image, but networking would be nice. Since ZipDisks were attached to the floppy disk controller and were over 100MegaBytes, this should be possible. i tried a long time ago to do this and spent too much time on it only to have it fail to boot. So if someone has reliable instructions on how to create such a nightmarish beast and edit it, please let me know. One image that can used for PXE and copied to a USB stick would be a plus. Too bad manufacturers don't supply a single bootable Linux ISO containing all their firmware updates, that would be easy to boot over-the-lan and have networking. HP servers do this and it is awesome.

  • How Do Online Virus Scanners Work?

    - by user185812
    I have seen a lot on free online virus scanners available online lately. I was considering trying one of them out, but I have a question. If I have company word documents, excel spreadsheets, etc on my computer, do these scanners just take a copy of everything on my hard drive, put it on their server, and search through them? Or do they just use virus definitions and scan through my computer without taking a copy of all my data?

  • LINQ 2 SQL: Partial Classes

    - by Refracted Paladin
    I need to set the ConnectionString for my DataContext's based on an AppSetting. I am trying to do this by creating a Partial Class for each DataContext. The below is what I have so far and I am wondering if I am overlooking something? Specifically, am I dealing with my DataContext's correctly(disposing, staleness, etc)? Doing it this way will I have issues with Updates and Inserts? Is the file BLLAspnetdb.cs useful or neccessary in the least or should all of that be in the generated partial class AspnetdbDataContext file? In short, is this an acceptable structure or will this cause me issues as I elaborate it? dbml File Name = Aspnetdb.dbml Partial Class File Name = Aspnetdb.cs partial class AspnetdbDataContext { public static bool IsDisconnectedUser { get { return Convert.ToBoolean(ConfigurationManager.AppSettings["IsDisconnectedUser"]) == true; } } public static AspnetdbDataContext New { get { var cs = IsDisconnectedUser ? Settings.Default.Central_aspnetdbConnectionString : Settings.Default.aspnetdbConnectionString; return new AspnetdbDataContext(cs); } } } My Created File Name = BLLAspnetdb.cs public class BLLAspnetdb { public static IList WorkerList(Guid userID) { var DB = AspnetdbDataContext.New; var workers = from user in DB.tblDemographics where user.UserID == userID select new { user.FirstName, user.LastName, user.Phone }; IList theWorkers = workers.ToList(); return theWorkers; } public static String NurseName(Guid? userID) { var DB = AspnetdbDataContext.New; var nurseName = from demographic in DB.tblDemographics where demographic.UserID == userID select demographic.FirstName +" " + demographic.LastName; return nurseName.SingleOrDefault(); } public static String SocialWorkerName(Guid? userID) { var DB = AspnetdbDataContext.New; var swName = from demographic in DB.tblDemographics where demographic.UserID == userID select demographic.FirstName + " " + demographic.LastName; return swName.SingleOrDefault(); } } see this previous question and the accepted answer for background on how I got to here... switch-connectionstrings-between-local-and-remote-with-linq-to-sql

  • ASUS P6X58D and 12 GB of RAM

    - by Hunter
    I just assembled my new PC and it screams, BUT it's only recognizing 8 GB of RAM in BIOS and OS rather than the installed 12 GB. In the BIOS the RAM was registering at 1066 MHz so I set it to 1600 MHz. I updated the BIOS to the latest non-beta release. http://www.asus.com/product.aspx?P_ID=wurRaDZ8lo4Ckukj OS: Windows 7 Ultimate 64-bit Motherboard: ASUS P6X58D Premium CPU: Intel Core i7 920 RAM: CORSAIR XMS3 12 GB (6 x 2 GB) 240-Pin DDR3 SDRAM DDR3 1600 HDD: Intel 80 GB SSD SATA II Power supply: Kingwin 1000 W Modular I've installed the Beta BIOS 0808 but no luck!

  • Replacing stock Core 2 Duo heatsink fan (just the fan really) with a Dell CPU fan

    - by user647345
    My old heatsink fan broke and I'm trying to reconnect its plugs to a new fan. My Dell CPU fan has some custom Dell plug. I snipped the old fan's wire in half and kept the plug on the end of it. I want to connect it to the Dell fan wire to the plug. The motherboard is a P5Q-e, the stock Core 2 Duo fan was .20A and the dell is .70A. Is that going to matter? The wire from the fan has four wires, the wire with the plug has four wires. They share three, of the four colors: red, black, and blue. Dell's fourth wire is white, while the plug's fourth wire is yellow. Is it safe to assume that I just connect the yellow and the white plug together and match the rest up? I don't want to take any risk of damaging anything. It runs fine passively without a fan, but I have speedstep on, so I would like to use this fan and just fasten it to the heatsink with some twist ties and paperclips and call it a day.

  • How to get Windows 7 to automatically connect to an ad-hoc network?

    - by George Edison
    I have two machines - one is running Ubuntu 12.04 64-bit and the other is running Windows 7 Starter Edition (32-bit). The Ubuntu machine is connected to the Internet via the eth0 interface. That machine also has a wireless network interface (wlan0) that is currently functioning as an ad-hoc network. I can connect to the ad-hoc network just fine with the Windows machine but each time I wish to do so, I must manually initiate the connection and enter the password. Is there some way to instruct Windows to automatically connect to this network (an option I have for standard wireless networks but not ad-hoc networks)?

  • Set mouse or keyboard button to simulate left click and hold or rapid left click repeating in Windows?

    - by miahelf
    Does anyone know a way to configure Windows 7 or use third party software to do this? I would like to click my middle mouse button and have it tell Windows to left click and hold until I click the middle mouse button again. A keyboard key would be fine as well. Some games and apps have me holding down the left mouse button for a long time and I would like to reduce the stress on my mouse hand. Also, I would like to do a similar thing but have it repeatedly click the left mouse button automatically if possible. If none of that is possible, how about temporalily setting a keyboard key to achieve a left mouse button emulation?

  • Clonezilla restore from Samba - no 'restoredisk' option

    - by MT_Head
    I used a CloneZilla LiveCD to back up a couple of Windows machines to a Samba share. Now I'm trying to restore those images, and CloneZilla won't even give me the 'restoredisk' or 'restorepart' options on the menu. I'm guessing that this is because CZ isn't recognizing a valid image... but why? Here's a listing of the folder on the Samba share: -rwxrwxrwx 1 marc users 319 May 31 03:45 blkdev.list -rwxrwxrwx 1 marc users 5307 May 31 04:41 clonezilla-img -rwxrwxrwx 1 marc users 4 May 31 04:31 disk -rwxrwxrwx 1 marc users 16091 May 31 04:31 Info-dmi.txt -rwxrwxrwx 1 marc users 11029 May 31 04:31 Info-lshw.txt -rwxrwxrwx 1 marc users 1502 May 31 04:31 Info-lspci.txt -rwxrwxrwx 1 marc users 170 May 31 04:31 Info-packages.txt -rwxrwxrwx 1 marc users 80 May 31 04:41 Info-saved-by-cmd.txt -rwxrwxrwx 1 marc users 10 May 31 04:31 parts -rwxrwxrwx 1 marc users 2097152000 May 31 04:06 sda1.ntfs-ptcl-img.gz.aa -rwxrwxrwx 1 marc users 247361656 May 31 04:08 sda1.ntfs-ptcl-img.gz.ab -rwxrwxrwx 1 marc users 823182034 May 31 04:31 sda2.ntfs-ptcl-img.gz.aa -rwxrwxrwx 1 marc users 36 May 31 03:45 sda-chs.sf -rwxrwxrwx 1 marc users 31744 May 31 03:45 sda-hidden-data-after-mbr -rwxrwxrwx 1 marc users 512 May 31 03:45 sda-mbr -rwxrwxrwx 1 marc users 315 May 31 03:45 sda-pt.parted -rwxrwxrwx 1 marc users 285 May 31 03:45 sda-pt.parted.compact -rwxrwxrwx 1 marc users 259 May 31 03:45 sda-pt.sf (I've been experimenting with various permissions trying to get this to work; that's why they're currently all "rwxrwxrwx"...) I've got my CZ LiveCD stuck in a (different) machine with a 160GB SATA disk that I'm fine with overwriting; although CZ doesn't show a directory listing, it does show that the correct folder is mounted as /home/partimag. But a moment later, after selecting either Beginner or Expert, I'm only presented with the "savedisk", "saveparts", and "exit" options. What am I doing wrong? I am confident that the initial backup was successful; I can post the log if desired, or any other information that might be germane. Edit: I've copied the contents of the folder onto a 16GB USB stick and set THAT as /home/partimag. Still nothing. What the hell is CZ looking for?

    Hi there, I open a .doc file in Word 2007 (sorry I am unable to supply the .doc) which pops up with a message above the document "Security warning: Macros have been disabled" but there are no macros shown in the macros listing and no functionality displayed in the VBScript editor. Why does Word think this document contains macros and how can I remove them to prevent the warning? Thanks, Tom

  • Router reconfigures PC's and they can no longer access the internet via hardwired connection to DSL Modem

    - by zchads
    Router reconfigures PC's and they can no longer access the internet via hardwired connection to DSL Modem. Hardware Information: Buffalo Wireless Router/access point, Model: WZR-HP-G300NH-AP DSL Modem: Generic (actually not sure of manufacture). Service Provider: TOT (Thailand) Laptop-1: Windows XP and Belkin PCMIA Network Card Laptop-2: Windows XP unknown network card & Wifi Laptop-3: Windows 7 unknown network card & Wifi Outline of Problem/actions taken: After a recent power failure the router and laptop-1 connected to router were no longer able to access the internet. Actions taken to try and recover internet access: Using Laptop-1 tried to configure Router with PPPoe settings using software from Router Manufacture. During the installation process a Timeout error was experienced, unable to connect to WAN. Used Internet Explorer to communicate directly with Router using IP address. Changed settings to use PPPoe settings given by ISP. Router was not able to communicate with Internet. Repeated steps 1-4 again with no success. Reset Router and DSL modem. Repeated steps 1-4 again still no success. Tried connecting Laptop-1 directly to DSL to gain access to internet to research problem. No Network connection with DSL could be established…connection would be established for a second and then be lost and didn’t appear long enough to actually connect to DSL. Replugged LAN back into Router and connection was regained with laptop-1. Replugged Laptop-1 directly into DSL and again unable to establish network connection. Uninstalled network card and all of its drivers on Laptop-1. Reinstalled network card and drivers and tried connecting directly to DSL. Still unable to make network connection. Plugged DSL into Laptop-3 and Internet connection was established. Being Laptop-3 does not have a CD-Rom, Laptop-2 was tried to connect to the router. With Laptop-2 steps 1-7 ended up being repeated without success. Tried plugging Laptop-2 directly into DSL and again no network connection could be established. Using Laptop-3 with a direct connection to DSL downloaded latest Router FW. Installed router FW using Laptop-1. Tired the installation process again without success. Being desperate reinstalled OS on Laptop-1 still not success. Tried using “ipconfig” with router to see what was going on without success. With laptop-1 connected to DSL went through the “ipconfig /…” inputs to see if anything made a difference. Being the network card was not able to make a connection this provide very little information “media disconnected”. So now I have a router and two laptops which are unable to connect to the internet and sure could use some advice/help.

  • Two instances of Windows Vista on boot up after failed clean install

    - by Dwayne
    I tried to install a clean version of Vista but failed. I ended up with Windows and Windows.old on my C: drive and a dual boot option on boot up. I gave up and booted up the old version and tried to rename the Windows.old to Windows and was asked if I wanted to merge the two folders. I answered yes and all seemed OK until I booted up this morning and was given the choice of two versions of Vista. The first one is the one that failed to installed correctly and the second one is the old version. How can I get rid of the failed installation? I got rid of the bad boot via MSCONFIG. Here is my current situation: several hard drives installed Using C: as my boot drive a much larger drive (H:) for storing most of my files. I found a subfolder in my C:\windows folder named windows. Upon inspection I determined it to be older than the C:\windows folder and therefore it must be the older, working version of the boot. I renamed the C:\windows folder to c:\windows.bad and moved the sub windows to the C: root directory. I also copied it to the h: drive. Now MSCONFIG reports that the copy that is booting is the h: copy. How can I change it back to the C:\ copy and can I delete the C:\windows.bad file set?

  • New install indicator while install updating on Ubuntu

    - by Phuong Nguyen
    In the update manager of ubuntu I see several libraries marked with New Install. I don't know what is the benefit I can get from that New Install? What if I just want a normal upgrade, not a New Install? (I have 3 Linux Kernel versions right now (that I can see and select from Grub menu), and I think I don't need all of them since I always use the latest Kernel).

  • MacPorts, Fink, etc.

    - by Ben Alpert
    On my Mac OS X (10.5, soon to be 10.6) machine, how would you recommend I install various software that's been ported from Linux? I don't install such software very frequently, but I've been using MacPorts and it always seems quite slow, presumably because it has to compile the packages on-the-fly. I'd much prefer a package management system that has binary packages, saving me the need to compile things every time I want to download something new. I think Fink has binaries for some of the packages, but I usually see MacPorts recommended as the system to use. Which do you think works better and why? (Or is there another system that I haven't heard of?)

  • Remotely push DNS server to client via OpenVPN

    - by wishi
    Hi! When I try to push a DNS server via the OpenVPN server-config I don't get that server to be the first DNS server on the connected client system. It ends up being specified as an alternative DNS server. push "dhcp-option DNS 89.238.75.146" # DNS-Server 1 (local djbdns) To overcome certain network restrictions, if they're at place, I use 443 TCP. - That means that my DNS queries are sent via TCP (if I manually reconfigure the DNS server), which doesn't scale very well from a performance perspective. Are there any kewl solutions for that? Marius

  • Ignore mapping when in text input box

    - by Art
    I have AutoHotkey set up in a way that is recognises Cmd-Left and Cmd-Right keystrokes as back/forward navigation in Chrome. Problem is that it also recognises those keys being pressed while I am entering text in textboxes. However when entering text, I'd would like those key combinations to carry out different function - jump to beginning/end of the line, similar to Ctrl-Left/Right. Is there a way to have one mapping working for text boxes and another mapping for everything else in AutoHotkey?

  • DVI vs VGA on Windows 7

    - by Joe Philllips
    I have a 3 monitor setup (each monitor is exactly the same). Two videocards, each with one splitter (one DVI and one VGA). I have two monitors hooked up using DVI and the third is connected through the VGA connection. I am running Windows 7. If I resize a window from one DVI monitor to the other, it's not a problem. It does so very smoothly. If I resize a window on the VGA monitor it is extremely choppy. Why? It's not choppy on other machines with only VGA connections. Has anyone else noticed this?

  • Downloads on Vista Home Premium start off fast but slow down to 0 Kb/s and hang

    - by user66265
    I have Windows Vista Home Premium on my computer and everytime I go to download something, it starts out at about 1.5 Mb/s and stays there for about 3 seconds, then it slows down to 800 Kb/s and continues to drop until it gets down to 0 Kb/s and hangs. I've tried just about everything I can find such as uninstalling all firewalls/antivirus, doing the netsh rss,autotune, and chimney disable, and updating everything but it still continues to happen. I'd prefer not to reinstall but if I have to then I have to... EDIT: Figured it out, the router needed a firmware update

  • Why is windows 7 rejecting my key?

    - by acidzombie24
    I'm extremely confused. I have a genuine key and CD (I can take photos) and I am trying to install windows on my new tower. I believe this would be the 3rd PC i installed it (old, laptop now new tower). However i did change the HDD once but i doubt windows would think its a different computer bc of that. After going through phone activation it said i installed it on to many pcs..... i'm extremely confused. I'll be happy to deactivate it off my old tower if i knew how. I already grabbed all the files off of it. I tried to look up the amount of boxes i can install windows home premium on and found this http://en.wikipedia.org/wiki/Windows_7_editions What stuck out was this Maximum physical CPUs supported[40] 1 1 1 2 2 2 My new tower has 4cores (its the intel i7) but has two threads each so it sees 8. Does that have anything to do with this? But apparently ultimate supports '2'. I'm sure windows support more than 2 cpus so... what gives? Actually its physically one CPU so i guess the number of cores doesn't matter? Why is windows 7 rejecting my key?

  • How to mark received sites as read in StumbleUpon toolbar?

    - by Prashant
    In stumbleupon toolbar for Firefox there is a "92" text is displayed in above pic, these are basically sites sent to me by my stumbleupon friends, so whenever I have sites from my friends, there in the toolbar and when I clicks the Stumble button then it shows those sites to me instead any new site. You can say these are link are like new mails, so there are 92 new mails for me, but I don't want to check those I just want to mark them as read in a single click, and move further to read other old mails. So Is there any option to mark these sites (sent to me by my SU friends) as read, so that when I click Stumble button then new sites will be shown instead sites which are sent by my friends??

  • Is it possible to use a dual processor computer as your desktop?

    - by Ivo
    I've seen some people suggesting to get a motherboard that supports two processors and stick two Xeon Nehalem processors in it. Could you use this system as a desktop PC or is this useless or even impossible? It's more hypothetical question if Windows 7 would support such a set-up. I know you could just take an i7, but wouldn't two of those processors be a whole lot more awesome? Like the previous generation Skulltrails? The idea would be to have a motherboard like this ASUS Z8NA-D6C Dual LGA 1366 Intel 5500 ATX and two Xeons (since I don't think i7's could be used) Intel Xeon E5405 Harpertown to run something like Windows 7 Ultimate.
