I installed Veritas Backup Exec 9.1, and afterward noticed that Backup Exec could not recognize my 4mm DAT tape drive. The drive was using Microsoft-provided drivers. I downloaded the Veritas drivers, rebooted, and my server is in a blue screen loop. It gets to the GUI boot screen with the 2003 logo & progress bar, then blue screens and reboots before I can read it.
I managed to catch part of the message: IRQ_NOT_LESS_OR_EQUAL_TO. A Google search turned up several similar situations, though the solutions are hard to find. In my case, I cannot even boot into Safe mode. I attempted a Repair via Windows Setup, but no luck there either.
Any help would be greatly appreciated!!!
