I own an Alienware Area51 7500 and this morning the computer randomly froze up within the first minute of starting Windows (this happens from time to time) and I am always forced to reboot the computer, and it eventually works. This time, after the reboot XP didn't even boot up, and I got this error message, "Windows could not start because the following file is missing or corrupt: system32\DRIVERS\isapnp.sys"
After I googled this issue, I resorted to booting up with the Windows XP CD and using the recovery console. So I did, but once I pressed 'R' in the 'Welcome to Setup" screen, it told me that it was not able to find any harddrives on my computer...I have a RAID HD 250 each, working as a one 500 gig hd. I am out of ideas and hope, any kind of help will be appriciated.
Thank you for your time!

You need the driver disk for the RAID Controller, start up the computer with the XP CD, select the mass storage device when setup asks, insert the RAID floppy, then setup will see the drives.

You can let windows load its generic raid driver. Just watch for the prompt to press F6 to install raid drivers when you first boot from the cd.

So I should press F6 while the CD is loading, when it asks me to?
and this will enable me to access the Harddrive when recovery console is attempting to?
And will using the default Raid settings change or affect anything for the worse?

This should allow you to access the hard drives.

Nothing will be affected.

When I pressed f6 for the CD to load third party RAID utilities, it said, "Setup could not determine the type of one or more mass storage devices installed in your system, or you have chosen t o manually specify an adapter"
So, I am back to point zero :thumbsup:
I also use Acronis True Image, and I made a complete back up of my computer a few months earlier, yet I still do not wish to activate it, because I do not wish to loose the files I had added on in the past months. But, is there a way to use Acronis to just replace the missing isapnp.sys file? Just a thought...

To add on, the drives indeed do show in the BIOS, with RAID enabled.
But under the 'Onboard SATA-II Controller" option, SATA2 Mode is selected, and it
states that "Changing this might cause in data loss. If selected SATA2 Mode, the
system will not support RAID mode."
Then, I went on and checked out the RAID options, and this is what I saw.
Boot-N/A
ID-1
Status-healthy
Vendor-NVIDIA
Array-Stripe 465.77G

Your drives are OK. Windows XP cannot see this sata raid without the correct drivers. You need an external usb floppy, and the driver disk for this controller. dont mess with the bios settings, or the raid striping can get corrupted.

Alright that sounds simple enough. So let me get this straight. I can buy a Floppy Drive (preferably via USB) and download the correct drivers into a disk. Let the RC access the harddrive via the drivers in the floppy disk and hopefully put a new copy of the corrupt file.
But now I have some questions. First of all, how do I know what drivers to get? Also, once I do get the drivers into a disk, how do I make it work so that the RC can access the harddrives?

Through Alienware, here: http://4help.alienware.com/cgi-bin/alienwa...php?p_faqid=902

after you hit the F6 key, you will need to put the floppy in the drive and hit enter.

then the XP CD will be able to see the raid array.
