Win 98 does not start with external SCSI-devices connected to the Adaptec 2940.

When I start Win 98 with external SCSI-devices, like a scanner and an EZ-Drive, the system hangs up when Win 98
launches. The problem does not occur, when there is no
external cable connected to the scsi-host-adapter.
When I reboot without connected peripherals, windows corrects the registry and after a restart without a connected cable, everything works properly.

Do you have both internal and external devices attached to adaptec card?  Have you tryed going into ctrl a for scsi bios and disabling the onboard bios of the adaptec card.  A possible conflict in the bios memory range, see if this works.

1) Show if SCSI Bios map the disk and the external device rigth when you boot your PC

2) If yes, you may have a interrupt (Change on your card) problem or win98 try to boot on the smallest number. You need to set your boot disk to position 0 or 1

3) Install dos SCSI driver and after WIN98 (Don't forgett to update your drivers (aspicam and..)

Instead of looking at all the driver files and such, first check your SCSI Ids and make sure they don't conflict. The drivers shouldn't really matter, your PC should boot up just fine with no drivers so there is probably a conflict with the SCSI IDs or you haven't terminated the last device properly.
