I was beginning to think I was the only one having problems with my new Abit KT7A Raid! Yours sounds like the usual missing boot disk BSOD. My problem is a bit different: I don't get as far as a BSOD, my install stops when it says "Please wait while Windows examines your hardware" (or something similar). The only escape is to switch off. After two weeks I have found that the cause is the Raid contoller itself. If I connect the disk to the standard IDE interface and disable the RAID Controller windows 2k installs and runs fine. If I leave the disk where it is and just enable the RAID then the machine won't boot. I've tried both the floppy boot and bootable CD installs but get the same effect. The BIOS is the latest one on offer on the Abit Web Site.
