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