Restoring system to previous working configuration (WNT)

[Digiboy]

A problem arrived when I was updating the SCSI drivers on a functional Windows NT 4.0 system. I reboot after installation but find that the system is "broken" ( blue screen with some error message and memory dump). I realized that it is the wrong drivers for the SCSI card. Since the system boots from the SCSI card, I cannot start the OS and install the correct driver.

Is there a way in which I can easily (without doing a repair) restore the system to the previous working configuration? Is it necessary to use an emergency repair disk to repair a Windows NT system? If it isn't, how can I do it? Thx.

Does it boot far enough to give you the last known good option?

If not, is the partition NTFS or FAT. If it is FAT you can boot from a W9x boot disk and rename the system hive (C:\winnt\system32\config\system) to system.old and rename the system.alt file in the same directory to system. This may allow you to boot and make the required changes.
