Very Computer

  I have a scanner UMAX Astra 1220S with scsi card UDS-IS11 ISA on
DTC3118E
chipset, compatible to NCR5380, supported by Linux driver g_NCR5380.
This
card have not IRQ and DMA preffered.
  I compile SCSI support in module scsi_mod and module sg - support
generic
SCSI for scanner.

  Turn on modules:
insmod scsi_mod
insmod sg
->Ok.

 Then turn on module for SCSI card: (as wrinning in SANE site):

insmod q_NCR5380 ncr_irq=255 ncr_addr=0x240 dtc_3181e=1
ncr_irq=255 -> no IRQ, no DMA
and Linux halted. Reset on computer - single help for this situatuon.

SCSI device single - scanner. SCSI ID=1. Scanner have SCSI termitator.

  Before halt, Linux answer:
scsi0: interrupt not enabled. for better interactive performance,
scsi0: please jumper the board for a free IRQ
scsi0: at port 0x240 interrupts disable option CAN_QUEUE=16
CMD_PER_LINE=2 release=1
generic option AUTOPROBE_IRQ AUTOSENSE USLEEP, USLEEP_POLL=1
USLEEP_SLEEP=20 generic release=7
scsi0: Generic NCR5380/53C400 Driver
scsi: 1 host

Where the troubles?

I'd like to ask you some questions, because I seem to have nearly the
same problem as you had. By the way, did you get it running with the
DTC-card or did you buy another SCSI-adaptor?

I've got this DTC3181E-adaptor and an Mustek SP1200 attached to it. Did
your kernel recognize the SCSI-card on bootup and did you switch it to
PNP or to PNR (whatever this means)? My kernel always says:

scsi : 0 hosts.
scsi : detected total.

Then I tried to use pnpdump to get the io-adress of the card but pnpdump
didn't find the adaptor also my PNP-BIOS initilizes it correctly on
bootup.

On loading the dtc-module I got the message: resource is busy.

I could load the g_NCR5380-module but it didn't list any SCSI-card under
/proc/scsi/scsi.

Did you make similair experiences or did you even get it running?
