Well, I found the correct driver, I think. It was in the ATI System driver package, on this page: http://global.msi.com.tw/index.php?func=driverfile&dno=2427&i=1
However, I still can't get XP to recognize my drive by pressing F6 at install. Perhaps I'm not using the right files from this package (287MB!). I found what I thought might be the correct drivers in the following folder: ATIDrv/SBDrv/RAID4xx and copied all the files to a floppy. Windows sees this driver and loads it, but when it gets to the point of formatting a drive (or whatever the next step is after you hit F^ and load the driver), it says no HD found, hit F3 to restart (sure would be nice to have other options here, like load another driver).
So, here's more info about my system (read the posting guidelines since last time
mobo: RS480M2-IL BIOS 7093v39
RAM: G.Skill PC3200 1GBx2
HD1:Seagate Barracuda 7200.10 160GB
HD2:Maxtor Diamondmax20 160GB
Problem started when co-worker shut the machine off hard. On reboot, Invalid System Disk error and looking at RAID Bios shows drives in SYNC state. Removed the drives and attached to another machine, one looks fine so I clone it for good measure. The other is corrupted, XP wants to format as soon as it's mounted. Checking it with Filescavenger3 shows the files are still there, but I just reformat it since I have the good image of the other disk. Now I'm trying to fix the other drive, since it still comes up as Invalid System Disk, so I want to try either using the Recovery Console to FixMBR, or do a repair install of XP. I can't find the right driver to make this happen. I do have a disk with LastXPv2.11 that will recognize the drive, but it doesn't allow me to get into the recovery console or offer to repair xp. If you know how to extract the drivers from a slipstreamed disc, that might work too. Finally, I don't know if I've update the RAID bios, or if that happens when you update the mobo bios. I did update that to v39 and the RAID BIOS shows 4.2.50.
Sorry this is so long, any ideas to help get me going here would be fantastic
