• What needs to be considered when setting up for Linux Development? [closed]

  - by user123586

  I want to set up a box for Linux development. I have a working linux install with the usual toolchain and an IDE. I'm looking for advice on how to approach structuring accounts and folders for development. As the Perl folks say "There's always more than one way to do it." Left to my own devices, I'll come up with several unproductive ways of doing it before figuring out what an experienced Linux programmer would think obvious. I'm not looking for instructions to follow for a specific set of tools or a specific software package. Instead, I'm looking for insight into what decisions need to be made and how to make them, with understanding of the advantages and disadvantages of each individual choice. These are some of the questions that come up: Where to put sources Where to put built object files and libraries where to install what to set in environment variables what compiler flags matter and how do you manage them across several types of builds what configuration entries to make in an IDE how to manage libraries to support multiple environments how to handle different build versions such as debug vs release, or cross platform builds If you are an experienced Linux developer, the answers to these questions may seem trivial and obvious. I'd like to learn to make decisions about these questions that result in as little manual configuration as possible, given some existing sources, a particular IDE, or no IDE at all, a paticular set of development libraries etc. At this point you're probably thinking: Can you be more specific? Sure. But remember that I'm trying to learn how to think about this stuff, not just follow a recipie for a specific set of results. Example: Setup a project that uses CMake for some of its components, autogen.sh followed by configure for others and just configure for a few more: debug builds without an IDE debug builds in NetBeans debug builds in Eclipse debug build in Visual Studio all of the above with release builds for Linux, Mac and Windows. So... **What are your thoughts on an approach that works for all four? Do you have any advice on what to read?**

• Can not connect remotely to MySQL Server on Ubuntu 10.10

  - by BobFranz

  Ok I have searched google for two days trying to get this to work. Here are the steps I have taken so far: Clean install of Ubuntu 10.10 Install mysql 5.1 as well as admin Comment out the bind address in the config file Create a new database Create a new user that is username@% to allow remote connections Grant all access to this user to the new database EXCEPT the grant option Login on the server is ok using this new user and database on the localhost Login on the server is ok using this new user and database on the server internal network ip Login from a remote computer is ok using this new user and database using the internal network ip Login is not working when logging in with this username and database using the external ip address from the server or the remote computer. I have port forwarding enabled for this port and it is viewable from outside as confirmed by canyouseeme.org I have nmap'd using the following command on the internal ip and get the below result: nmap -PN -p 3306 192.168.1.73 Starting Nmap 5.21 ( http://nmap.org ) at 2011-02-19 13:41 PST Nmap scan report for computername-System-Name (192.168.1.73) Host is up (0.00064s latency).

• Grub Installation Failed: Fatal Error ... now what I do?

  - by eklavya

  I know there are some threads that touch this but I feel I have done something uniquely stupid. hence the post and plea for help. I am a beginner @ Linux. So I have a PC with a HDD (hard disk drive) and SSD (solid state drive) It was running Linux Mint /dev/sda1 - HDD Partition 1 - 2 TB (mounted this is /home /dev/sda2 - HDD Partition 2 - 1 TB (separate back up drive, i was backing up files to this) /dev/sdb1 - SSD Partition 1 - 100 GB (OS) /dev/sdb2 - SSD Partition 2 - 20 GB (Swap) The operating system was Linux Mint and was installed on the /dev/sdb1 i.e the solid state drive. I had partitioned off the sda into 2 TB and 1TB and presented the 2 TB as the /home to the OS. Anyway last night I decided to make a return to Ubuntu via the path of Elementary OS. Everything went fine with the install until it stated that GRUB installed failed and this was a Fatal error (no kidding I said). No I am stuck. I have definitely done something wrong and don't know what it is... My biggest pain is the files on the /dev/sda2. I want to save these before I try something drastic like wiping off the /dev/sda completely. So I have the following questions... Can I use a liveCD USB to save these files ? I can see the /dev/sda2 but was unable to access the files in the liveCD last not least ... how do I fix the main issue here. Why could the OS not install GRUB 2b... why is my SSD the /dev/sdb ... and not /dev/sda. Does that have something to do with it that my master boot record sits on the HDD /dev/sda and not /dev/sdb

• Free Hosting control panel

  - by John Maxim

  Hello All, I'm in the mid of researching for one of the best hosting control panels. The server I run is Ubuntu and I have some experience with ISPConfig 2 & 3. Since I haven't explored any others available, what are the recommended ones for an Ubuntu server? I asked because I find that there seems to be some disabling and modifications required for an Ubuntu server if I need to use ispconfig which causes the server to change its actual way of running. It's quite good though, but any more recommended ones ? Something more organic? which doesn't require much breaking and changing. I'm not asking for the simple one, I don't mind going extra mile to install a powerful one but just try sticking with most Ubuntu's conventions will be an ideal one for me. And of course, if there happens to be something that meets the requirement as mentioned "Ubuntu conventions" and also simple to install at the same time, that'd be a bonus. Thanks in advance.

• Why is "start in" needed for Windows scheduled tasks?

  - by GomoX

  We develop a web application that can be deployed on Windows or Linux. The Linux implementation uses cron, and the Windows one uses scheduled tasks to run a single PHP script that processes all scheduled tasks for our system. The task is scheduled using schtasks during the install process, like: This has always worked both under W2003 and W2008. A week ago a customer reported that scheduled tasks were not running. He is running on Windows 2008. We checked over and over and finally solved the issue by entering the folder that contains the .vbs script as the "start in" folder for the scheduled task. This said, there is no way to set up the "start in..." value from schtasks without using an XML definition of the tasks. XML definitions don't work in Windows 2003, so I would have to add windows version detection to the installer, additional testing, etc (I'd like to avoid this if at all possible). The only atypical thing I noticed about the install is that the system is installed in D:\ as opposed to the default C:\Program Files (x86)\, but I don't see how this would matter. All the paths are absolute in all the scripts. Can anyone suggest a reasonable solution for this?

• Booting Windows from different partition than system

  - by szamil

  I have bought an SSD disk, but my laptop (Dell Precision M6300) refuse to use it as a target disk for windows (AHCPI on/off, BIOS up-to-date). I can't exchange the disk unfortunately... But fortunately, I've managed to install windows using USB disk case. The problem is, that when I put that disk as my internal drive it can't boot. (Disk read error, Three Finger Salute ... ) So I tried with Linux (openSUSE), I manage to install it as well, but when I tried to boot GRUB from internal drive I get errors again. (Should I try GRUB2?) I figured out that I can boot into that internal hard drive's openSUSE system using small USB drive with GRUB, kernel and image on it. So, I just run GRUB from USB drive, it loads necessary stuff from the USB drive and then continues from the internal drive. I want to do the same with Windows. But GRUB (rootnoverify and chainloader +1) does not boot my windows on internal drive. The question: is there any chance to copy the critical windows' boot files into the USB drive, to make it possible to boot from that USB drive, but continue booting from internal (different in general) drive? The USB drive would became a system hardware key! ;-) Disk: Plextor M5S 128GB Sata III, laptop has Sata II, but it's compatible anyway, right?

• Running Tor relay on personal server: can this hurt?

  - by rxt

  I would like to install TOR as relay on a hosted personal server. I have loads of bandwidth that I don't use. It's not an exit point. Can this hurt my server somehow? Possible problems I'm thinking of are blacklisting the IP-address, or something similar. I know that exit points get blacklisted on many servers. So if I'm using Tor as a client, I will probably use a blacklisted IP-address for the outside world, so cannot access those sites. However, I'm running this on a server, and as a public relay. Could this hurt the functioning of and access to websites on this server? I could install it as a bridge. I'm a little confused about the difference between bridging and relaying. If I understand correctly the only difference is that a relay is public. Does this mean that bridging only works if I know someone and give them my IP-address?

• In-Page RSS Reader (Flash? Javascript?)

  - by Jonathan Sampson

  Has anybody ever seen any (no-installs-necessary) solutions to listing any RSS feed on any page of a website? Ideally it would consist of HTML (javascript if necessary) and require no downloads or installs. I am thinking of twitter-style apps that you load up in an iframe or via Javascript and in turn they show your latest tweets on the page - same concept, different content. Just looking for a shiny gadget, not able to write my own solution for this particular project.

• Windows Update broke Wirless driver - Can't get it working again

  - by private_meta

  I naively installed a driver update incoming from Windows Updates yesterday. That caused my Wifi on my Notebook (HP ELitebook 2740p) to break. The network is working as I tried it with my other mobile devices. When installing said driver, it told me that the installation failed. I tried to do a system restore, which did not help getting wifi connectivity back. The device said it was working, but did not get any wifi connection and did not discover any networks. What I tried next was to uninstall the device from my Device Manager and install either the current drivers found through windows, then I tried the same with the current drivers on the HP driver page. both of those attempts failed. It always tells me that installation failed when I uninstall and reinstall drivers. If I try to update the broken driver via internet, it tells me it is up to date, and in the device manager it still views as broken. Next, I 'played' around a bit and reinstalled drivers, and I managed to install drivers from 2012, and when trying to update drivers manually and picking drivers that match the device, it lets me choose between drivers from 2010 and 2014. 2014 would be the current one, picking the 2010 driver leads to the driver being accepted. However, no wireless network can be found. I'm pretty much out of ideas by now, short of reinstalling. The only option I can still think of was that the device broke at the exact moment I installed the new windows driver, but I find that a bit unlikely. Any help would be appreciated fixing this issue.

• Trouble with Remote Desktop pulling through printers. Drive Redirection works, and the ports created but not the printers

  - by Windex

  I've run out of things to look into. All the support documents have been gone through and still provide no resolution. I've checked the service permissions, (sc sdshow spooler) they all match up with other systems and what is output on the support documents. I'm nearly positive that the issue can't be permissions anyway as the software requires all users to be an administrator, so all users are a local administrator. (I haven't looked into why yet but its on the list, I was just recently brought into this team and we've put procedures in place for quick recovery.) We've applied hot fixes relating to RDS and printing, though I'm not sure which ones they were. I've combed through group policy and no where is printer redirection disabled. It's setup with all default values regarding the use and redirection of printers and a quick install of W2k8 R2 shows that it works by default. This dev install was joined to the same domain, placed in the same OU, shows the same policies applied, etc, etc, etc, The server generates all the correct redirected ports but no printers are created. It will also redirect drives without issue, this would seem to rule out the usermode service that handles redirects being broken. No events are logged related to any of the events and there are no events from the TerminalServices-Printer source. There were local printers setup. I didn't think it would mattter but as I was running out of ideas I tried deleting them all with no change. The TS was configured for the software it will be running before we checked out the redirection of printers so the other team responsible to setting up new servers wants to find a fix instead of reloading a new server. I'm not sure where or what else to look for. Any ideas?

• Have some questions about setting up a VPN to my private cloud servers

  - by Pure.Krome

  I've got a number of Virtual Servers running at a pretty big Cloud provider. They are all running Windows 2008 R2. I have a CISCO ASA firewall in front of them. Currently, I've got all ports blocked except 80/443/21/3386 (for Remote Desktop). I asked to have a VPN enabled on the firewall and they said it's easy to do BUT I need to use the 3rd party Cisco software. Now, I don't want to get into a debate about it .. but we don't want to install anything extra on our -client- computers. We all use Windows 7 and we love using the built in VPN client to connect to other private LANS we have setup in other locations. So i'm wondering what options I have to create a VPN tunnel to our private cloud LAN? All our cloud servers are part of WORKGROUP, so there's no Active Directory .. nor do we want to install all that. Secondly, we know we can open up a firewall port - so any ports for starting a VPN is fine! Lastly, I was thinking of just using one of the existing servers as the VPN server (and using the Windows VPN software) .. but I'm not sure this is a good thing? Remember - we just want to use the baked in VPN software in Windows 7 .. which is PPTP or SSTP or L2TP/IPSEC. I would -LOVE- to use some free OSS software. For usernames/passwords? We'd probably just have one account .. like U:Hithere P:whatever.. so we don't need any hardcore account management, like Active Directory, etc. So does anyone have any ideas?

• ESX 3.5 refuses to update

  - by Speeddymon

  I have a set of ESX 3.5 servers in 2 different datacenters. One is DR, one is production. They are on the same vlan and so I can access any of them on the private network from my vCenter server. Last month, as a learning experience (I hadn't dealt with ESX much before), I updated the DR server. Other than finding out that a couple of bundles had to be installed manually in order to get the rest to install from vCenter, it went off without a hitch. Now, I'm trying to do the same for our production servers and it is not working. I've googled around for the error I get during scan, and investigate loads of different solutions (editing the integrity file, checking DNS, etc) -- I did install the 2 bundles that had to be installed manually already -- but scan from vCenter is just not working. Side note: I did just scan the DR server again and that scan works fine so shouldn't be a problem with vCenter that has cropped up recently -- it has to be something else. The error I get is: Patch metadata for (servername) missing. Please download updates metadata first. Failed to scan (servername) for updates. I'm all out of ideas on how to make this work, so any help would be hugely appreciated.

• What causes "system call failed" and there are hanging ie processes?

  - by TecBrat

  System: Windows 7 Home Premium IE: 11.0.9600.17107 When I have had many, many apps and windows open, sometimes I'll try to access a folder and get a dialog that says "System Call Failed". I have found the fix for it is to open the task manager and End Process Tree on iexplore.exe and iexplore.exe *32. Often times there will be several of these even when I have closed all my browser windows. Does anyone have any experience with this error?

• Revamping an old and unstable IT-solution for a customer?

  - by cmbrnt

  I've been given the cumbersome task to totally redo the IT-infrastructure for a customer's office. They are currently running Windows XP all over, with one computer acting as a file server with no control over which users have access to which files, and so on. To top it off, this file server also functions as a workstation, which means it gets rebooted every time the user notices some sluggish behavior or experiences problems with flash games. To say the least, this isn't working for them. Now - I've got a very slim budget, but I need to set up a new server, and I wish to run Windows Server 2008 on it. I also need the ability to access the network remotely via VPN. Would it be a good idea to install VMware ESXi 4.1 onto the new server, and then run Windows Server 2008 as well as a separate Debian install for openvpn on it? I don't like the Domain Controller for the future AD to also run a VPN-server, because of stability issues when something goes to hell with either of them. There will be no redundancy though. However, I'm not sure if there is something to gain by installing a VPN solution on the Windows Server itself, when it comes to accessing file shares on the network via VPN. I don't know how to enable users logging in via the VPN to access the remote files, since they will be accessing the network from their own home computers (which is indeed a really bad idea, but this is what I've got to work with). They won't be logged in to the windows Domain, but rather their home workgroups. I need to be able to grant access to files in certain directories based on the logged in AD-user, but every computer won't necessarily be configured to log into the domain. I'm not sure how to explain this in a good way, but I'd be happy to clarify if somethings not clear. Any help would be great, because I've got a feeling that I can't do this without introducing a bunch of costly new rules when it comes to their IT-solution. I'd rather leave that untouched and go on my merry way to the next assignment.

• Removing expired self-signed certificate in IE9 (created with IIS7.5)

  - by Itison

  Over 1 year ago, I created a self-signed certificate in IIS 7.5 and exported it. I then installed it for IE9 (it may have been IE8 at the time), which worked fine until a year later when the certificate expired. I have put this off, but today I created a new self-signed certificate in IIS, exported it, and attempted to install it in IE9. The problem is that for whatever reason, IE cannot seem to forget about the old, expired certificate. Here's what I tried initially: Accessed my ASP.NET application and see the Certificate error. Clicked "View certificates". Clicked "Install Certificate" and then Next/Next/Finish. At this point, it says the import is successful, but it still only shows the expired certificate. I've tried simply double-clicking on the exported certificate on my desktop. Initially I chose to automatically select the certificate store, but then I tried it again and manually selected "Trusted Root Certification Authorities". I've also tried dragging/dropping the certificate over an IE window and clicking "Open". The process is then exactly the same as it is if I had double-clicked on the certificate, but I had hoped that this would somehow specifically tell IE to use this certificate. I tried opening MMC and with the Certificate snap-in, confirmed that the new certificate was added under "Trusted Root Certification Authorities". It was also under my "Personal" certificates (I guess this is where it goes by default). Nothing worked, so I went through every folder in MMC and deleted the expired certificate. I also deleted the expired certificate in IIS. Nothing has worked. Any ideas? I see no clear resolution and I can't seem to find any posts related to this issue.

• Folder Sharing NTFS permissions with Share Permission

  - by Muhammad Adly

  i have a problem on my domain, the history starting from when i had a server with WIN 2008 r2 installed with the following roles installed on it (AD, DNS, DHCP, File). From 1 month i decided to install a new server 2008 r2 server to get (AD, DNS, DHCP) and leave the file server on the old one. i did the following exactly: 1) robocopy all my data on external HDD 2) Install a new server with 2008 r2 3) transfer all 5 roles to transfer the domain to the new server (MainDC) 4) issue (NETLOGON, SYSVOL) not transferred but i decided to reinitialize them again an now they are operating (MainDC) 5) re-create and re-configure a new GPOs and link it to my OUs 6) reinstall Old server operating system with a fresh installation of WIN 2008 R2 (FileServer) 7) join my domain with my domain credentials. the issue when i tried to share folder on \fileserver the permissions that i had set in sharing permissions are applied on the main shared folder and subfolders. the security settings are not applied. i.e. Say i'm sharing \fileserver\MainFolder with sharing permission for Authenticated Users that can read, so every one can read this main shared folder, if i set security permission for \fileserver\MainFolder\User1 that User1 can Read\Write\Modify. User1 can not perform this processes when accessing it from Network Share, i tried alot of steps from topics online get ownership for folder, remove inheritance from parent folder, applying changes for child objects, i tried also to construct a new folder structure but also the same issue, i tried another host PC, also i get the same issue.

• fglrx-legacy-driver not seeing Radeon HD 4650 AGP

  - by Rocket Hazmat

  I am running Debian Squeeze on an old Dell Dimension 8300 box. It has an AGP Radeon HD 4650 card. I use this machine to mine bitcoins, and today I noticed that the machine had rebooted! My precious uptime! Anyway, my miner wouldn't start, so I figured might as well update my graphics driver, maybe that would fix the issue. I went to amd.com and downloaded the newest driver (12.6 legacy), but after installing it, aticonfig gave an error: aticonfig: No supported adapters detected I uninstalled the driver and figured I'd try to install it from apt. AMD has dropped support for the HD 4000 series in fglrx, forcing me to use fglrx-legacy-driver (currently only in experimental). In order to install this, I had to update libc6 (and some other important packages, like gcc), I had to use their wheezy versions. I finally got glrx-legacy-driver installed, but I still got: aticonfig: No supported adapters detected Why isn't the driver finding my video card? I have a hunch it has something to do with the fact that it's an AGP video card. Here is the output of lspci -v (why does it say Kernel driver in use: fglrx_pci?): 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV730 Pro AGP [Radeon HD 4600 Series] (prog-if 00 [VGA controller]) Subsystem: Advanced Micro Devices [AMD] nee ATI Device 0028 Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 16 Memory at e0000000 (32-bit, prefetchable) [size=256M] I/O ports at de00 [size=256] Memory at fe9f0000 (32-bit, non-prefetchable) [size=64K] Expansion ROM at fea00000 [disabled] [size=128K] Capabilities: [50] Power Management version 3 Capabilities: [58] AGP version 3.0 Kernel driver in use: fglrx_pci

• 2.6.9 Kernel on virtual server (non upgradable) - any expected problems?

  - by chris_l

  Hi, I'm considering to rent a virtual server (for me personally). The product I'm currently looking at offers IMO fair pricing, very good hardware etc. The only problem is, that I won't be able to do an upgrade to a newer kernel than 2.6.9 (running Debian Etch). Also, I can't install my own kernel modules. (The server runs with Virtuozzo, so as far as I understand it, it just does some chroot instead of a real virtualization (?)) I want to run GlassFish, Postgres, Subversion, Trac and maybe some other things on it. It will also have to employ a firewall, and provide OpenSSL for https. Ideally, it would also be able to do AIO (asynchronous IO), which could speed up some server I/O. Should I expect problems with that old kernel version, in conjunction with the software I want to install (I'd like to use current versions of the software)? One thing I already found out, is that you can't do everything with iptables, since some kernel modules are missing/things are not build into the kernel. GlassFish v3 appears to run fine at first glance. I was able to test the server for a few hours. Installing my whole setup wasn't feasible in that time, but what I can say is, that it's amazingly fast for an entry-level vserver, especially hard disk and network performance (averaging at ca. 400MBit/s). So if the kernel won't be a problem, I'd really like to take it. Thanks, Chris PS Exact kernel version: 2.6.9-023stab051.3-smp

• On ubuntu 10.04, what is the recommended RoR stack?

  - by Kurucu

  I can't find clear answers / methods on this. As seen elsewhere, passenger and RoR under apache gobble up ram on my VPS. I've tried a multitude of stacks and implementations, currently resting on a sub optimal apache/cgi/rails configuration, which has swapped my ram usage for CPU time and slow response to requests. Can anyone recommend an efficient and preferably simple to administer method of setting up rails apps in ubuntu 10.04 server?

• Windows XP Freezes

  - by Jim Fell

  Hello. I'm running a machine with Windows XP Professional 64-bit. Every so often, it will freeze for no apparent reason. That is, everything stops responding, except the mouse. I can move the mouse around, but I can't click on anything. Keyboard input is also not accepted/received when this problem occurs. The three-finger salute fails to bring up the Task Manager. Even pressing the power button on my computer fails to shut it down. The only way out of this that I have found is to hard-reboot the machine (i.e. pull power or hold power button in for 10 seconds). This problem was occurring on the system when it had all its updates and after a fresh install when not everthing was quite yet updated. I've run the Scandisk utility and the latest version Memtest86 that supports 64-bit architecture; neither found any errors. The last time this happened was on a fresh install of Windows. Only Nero Essentials, Avast antivirus (disabled), Firefox, and Spybot were installed. I was not running Nero, Firefox, or Spybot at the time, and Avast was disabled, so I'm pretty certain this is a Windows issue. Is anybody familiar with this problem or have any pointers? Thanks.

• Designing a persistent asynchronous TCP protocol

  - by dogglebones

  I have got a collection of web sites that need to send time-sensitive messages to host machines all over my metro area, each on its own generally dynamic IP. Until now, I have been doing this the way of the script kiddie: Each host machine runs an (s)FTP server, or an HTTP(s) server, and correspondingly has a certain port opened up by its gateway. Each host machine runs a program that watches a certain folder and automatically opens or prints or exec()s when a new file of a given extension shows up. Dynamic IP addresses are accommodated using a dynamic DNS service. Each web site does cURL or fsockopen or whatever and communicates directly with its recipient as-needed. This approach has been suprisingly reliable, however obvious issues have come up and the situation needs to be addressed. As stated, these messages are time-sensitive and failures need to be detected within minutes of submission by end-users. What I'm doing is building a messaging protocol. It will run on a machine and connection in my control. As far as the service is concerned, there is no distinction between web site and host machine -- there is only one device sending a message to another device. So that's where I'm at right now. I've got a skeleton server and a skeleton client. They can negotiate high-quality authentication and encryption. The (TCP) connection is persistent and asynchronous, and can handle delimited (i.e., read until \r\n or whatever) as well as length-prefixed (i.e., read exactly n bytes) messages. Unless somebody gives me a better idea, I think I'll handle messages as byte arrays. So I'm looking for suggestions on how to model the protocol itself -- at the application level. I'll mostly be transferring XML and DLM type files, as well as control messages for things like "handshake" and "is so-and-so online?" and so forth. Is there anything really stupid in my train of thought? Or anything I should read about before I get started? Stuff like that -- please and thanks.

• Can I have a single solid state drive and a RAID array on the same machine? [closed]

  - by jaminto

  Hi- To summarize, i'm looking to use a single solid state drive as my primary drive, and two conventional sata drives in a RAID 1 configuration for data. I am trying to install 64-bit Windows 7 onto this configuration. Is this possible? Here are the details: I built a desktop that has been running 64-bit Vista on two 500Gb in a RAID 1 array for a few years. I just purchased an Intel X25-M 80Gb Sata Solid-State Drive, and was planning on using this a my primary drive, and keeping the RAID 1 array as my data drive. I added the SSD drive and in the RAID setup, configured it as a RAID 0 array of only one disk. Then, I tried to do a clean install of windows 7 64-bit, but got stuck in the "Missing driver for CD/DVD drive" black hole of selecting driver files and Windows telling me that i don't have the appropriate driver for my hardware. The missing hardware is NOT a CD/DVD drive, since i'm installing off of my only CD/DVD drive. Plus at one point i was able to point it at a driver for my raid controller, and then my hard drives magically showed up as browsable sources for finding drivers for some other unnamed device that setup couldn't recognize. After a few hours of trying drivers (this was a very slow process) i decided to reboot and look at the BIOS settings. I'm using an ASUS M2A-VM motherboard which has an ATI SB600 RAID controller on board. I switched the "On board SATA Type" setting from "SATA" to "AHCI" thinking that since AHCI is an Intel thing, this would help. Unfortunately, this abandoned my RAID configuration, and my previously mirrored drives are showing up as separate drives when i boot into my current windows installation. Am i trying to do the impossible here? Should i just buy a separate SATA/RAID PCI card and plug the SSD into that? Any help would be greatly appreciated.
