Hi All:
<BR>
<P>Sorry if this is O/T, but I really need help. And I figure someone here
<BR>
must have gotten this combination to work. :)
<BR>
<P>I have a HP ScanJet IIc that came with an old SCSI card HP calls the
<BR>
C1750A... it's based on the NCR 53c400, and it is non-PNP, and that's
<BR>
about all I know about it. Here's the problem: Everytime I try to
<BR>
load the g_ncr5380 driver, I completly freeze the system (look Ma! I
<BR>
can crash Linux! :) ) On boot-up, Linux reports that it does not know
<BR>
of any SCSI hosts. I've read the documentation for that SCSI driver,
<BR>
searched this mailing list, danced in a circle around the scanner
<BR>
clapping my hands and chanting, and I can't figure out how to fix this!
<BR>
<P>My setup:
<BR>
PII-233, 96 megs RAM
<BR>
Running Redhat 6.0, kernel upgraded to 2.2.14
<BR>
<P>To load the driver, I type:
<BR>
<EM>&gt; modprobe sg (for the generic SCSI driver)
</EM><BR>
<EM>&gt; modprobe g_NCR5380 ncr_irq=255 ncr_addr=0xc800 ncr_53c400=1
</EM><BR>
<P>The card's dip switches are set so it uses address 0xc800.
<BR>
I also tried to set ncr_irq =254 for autoprobe.
<BR>
<P>The driver reports that the device is busy, then it freezes everything
<BR>
up.
<BR>
<P>I don't have any other SCSI devices, and have never used one under
<BR>
Linux, so if anyone can take me step-by-step to help get this thing
<BR>
going, that would be great!
<BR>
<P>Thanks for the help!
<BR>
