Hi, I've been building computers for several years for a living. I know how to install drivers for SATA/RAID/etc at the f6 prompt. I'm using the latest BIOS (f12, also tried f7 and f10 which are supposed to support 64-bit). When trying to install XP 64-bit from the MS trial CD, I load the RAID 64-bit drivers at the f6 prompt. Normally with 32-bit, if the drivers aren't loaded properly I can't get past the "agreement" page, as it will say no hard drive is found. However this is finding the hard drive, formatting it, and copying the setup files. Upon the first reboot, it loops back to the CD instead of finishing the installation. If I change BIOS boot back to the hard drive during the first reboot, it errors. (Can't recall exactly, but missing windows system file of some sort). Had XP Pro 32-bit installed previously with no problems and have it installed again afterward with no problems. Anyone else seen this and/or have a fix for it? Any and all help is much appreciated. :-) System Specs: Gigabyte K8NXP-SLI 3700+ San Diego 2 X 1g OCZ PC4000 Gold 2 X 200G WD SATA2 (RAID 0) 2 X 120G Seagate SATA (RAID 0) OCZ 600W Powerstream 2 X BFG 6800U (SLI) Exos2 Water Cooling on CPU and Vid cards
