  Hi All:

  Sorry if this is O/T, but I really need help. And I figure someone here
  must have gotten this combination to work. :)

  I have a HP ScanJet IIc that came with an old SCSI card HP calls the
  C1750A... it's based on the NCR 53c400, and it is non-PNP, and that's
  about all I know about it. Here's the problem: Everytime I try to
  load the g_ncr5380 driver, I completly freeze the system (look Ma! I
  can crash Linux! :) ) On boot-up, Linux reports that it does not know
  of any SCSI hosts. I've read the documentation for that SCSI driver,
  searched this mailing list, danced in a circle around the scanner
  clapping my hands and chanting, and I can't figure out how to fix this!

  My setup:
  PII-233, 96 megs RAM
  Running Redhat 6.0, kernel upgraded to 2.2.14

  To load the driver, I type:
  > modprobe sg (for the generic SCSI driver)
  > modprobe g_NCR5380 ncr_irq=255 ncr_addr=0xc800 ncr_53c400=1

  The card's dip switches are set so it uses address 0xc800.
  I also tried to set ncr_irq =254 for autoprobe.

  The driver reports that the device is busy, then it freezes everything
  up.

  I don't have any other SCSI devices, and have never used one under
  Linux, so if anyone can take me step-by-step to help get this thing
  going, that would be great!

  Thanks for the help!
  Mitch O'brien
