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.

I have a HP Scanner and a external SONY CDR with my Adaptec 2940 and Win98 works finely

DON'T Forgett the terminaisons

Sorry I don't speak english very well :-)
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.
