I forgot to say that computer starts working regularly as soon as the
scan is over, I don't need to reset it.
After some experimenting, I found something strange: my modem-fax wasn't
working anymore. When I sent a fax, it sent part of the first page then
hung up.
Removing the SCSI controller fixed the problem.
Modem was on COM 3 IRQ 5, and that IRQ had been reserved in BIOS as
"Legacy ISA".
I load the scsi module with the command:
modprobe aha152x aha152x=0x140,11
The SCSI Adapter has been set with its utility 1505ACFG.EXE to IRQ 11,
SCSI ID 7 (default) and "NO DMA" (I tried with DMA 5 or 6 but nothing
changes).
When scan begins, everything freezes until scanning is over. Then
system goes back working.
If I am connected with X-Windows, I get disconnected.
I moved the modem on COM-4 IRQ 2/9.
Ethernet card is a PCI P&P NE-2000 clone set on Interrupt:5 Base
address:0xe800.
I also have a ISA ISDN card set on 0x180, IRQ 10.
Should I get a different SCSI card?
Thanks.
