If while your loading all your ide and scsi drivers during text mode win2k setup and right before the screen font change you get 0x0000007f BSOD with with the next number being all 0s, check for a Dynamic Drive Overlay on the Primary Master drive. Dynamic Drive Overlays allow older DOS based Windows operating systems to access big hard drives that the BIOS can't. I was using Maxblast 7.04 I spent 3 days trying to figure out why windows 2000 refused to install.
