Thread: NCR SDMS SCSI hanging? (EDS / DRS LXI Military Laptop)

    Default NCR SDMS SCSI hanging? (EDS / DRS LXI Military Laptop)

    Hi All,

    I've just acquired a late 90s military laptop, but on boot-up it hangs after loading the SCSI BIOS. The last message to appear on the screen is:

    NCR SDMS (TM) V3.0 PCI SCSI BIOS, PCI Rev 2.0
    Copyright 1993 NCR Corporation
    NCRPCI-3.05.03

    I've tried comparing the BIOS settings to an identical machine and saw nothing different, and I've also tried adding a terminator to no avail.

    Does anyone have any idea what could be going on?

    Thanks
    -Tom

    What happens if you disable the SCSI device(s)?
    If you're looking for DS/DD or DS/HD 3" or 5" floppy disks, PM me. I've got some new, used, and factory over-labeled disks for sale.

    There aren't any SCSI related options in the main BIOS. Is there a key combination to enter this SCSI BIOS, or does it need a boot floppy to change the settings?

    I'm not sure if NCR BIOS has any key combination. It seems to be very simple in comparison to Adaptec etc. IIRC NCR SCSI is implemented differently to most other addon controllers. I think the BIOS is weirdly tacked onto the system BIOS. Have you tried connecting a drive to it? I had a controller once that would hang for minutes before it timed out if there wasn't a drive connected to it.

    I don't suppose you have any pictures of it...
    Current projects: reassembling a Hero 1, fixing another Hero 1, fixing a spare VIC-20, among other things...

    I have, it detects it but doesn't continue beyond that point.

    Will do when I find my SD card.
    Here's an identical machine though

    Turns out the issue was caused by the BAMS controller card. I assume it was an IRQ conflict, but I have no documentation for the card.
