I can't get my XP Pro system to boot the RAID drive. Specs: Powerspec B647, Intel Core 2 Quad, 4 GB RAM, two 500 GB mirrored RAID hard drives (RAID controller drivers integrated into XP via nLite). The RAID BIOS setup utility shows the following: Boot: N/A Status: Healthy Vendor: Nvidia Array: Mirror Size: 465.76G When I boot to Safe Mode: computer reboots repeatedly after the *.sys enumeration list completes. When I boot to normal mode: got BSOD 0x000000BE with "An attempt was made to write to read-only memory." I performed a chkdsk /r in Recovery Mode and no errors were found. I performed a fixmbr in Recovery Mode and got some scary warnings as follows so I decided not to go through with it: 1.) "This computer appears to have a non-standard or invalid master boot record." 2.) "Fixmbr may damage your partition tables if you proceed. This would cause all partitions on the current hard disk to become inaccessible." 3.) "If you are not having problems accessing your drive, do not continue." Can someone make sense of the next steps I should take to get XP to boot properly? Thanks.
