OK, here's the configuration:

    16MHz NEATsx 386sx motherboard, w/4, 1M SIPPs
    Micropolis 1578-15 330Mb HD
    Hercules clone display adapter
    IBM PC-DOS 3.3

The other cards are apparently irrelevant, as the following troubles
occured with everything else removed from the system.

The 1542B is configured with BIOS enabled. I've tried DMA channels 5
and 0, and port addresses 330, 334 and 130 (the latter two with BIOS
disabled & ASPI4DOS.SYS installed). I haven't bothered to change the
interrupt/IRQ from the default 11, since the 1522 I'm using is setup
on 11 and works fine.

At bootup, the SCSI BIOS reports that it found the drive at 0/0, and
that it's been installed as drive C. OK so far.

When I try to partition the drive with FDISK, "Create a DOS partition",
the system reboots.

Next attempt, I start up the BIOS utility with debug, g=dc00:6.
 
It shows no devices, the 1542's LED and the drive's LED remain on for
a while, then it reports "TIMEOUT ERROR/SCSI INQUIRY COMMAND".

This seemed like a dead end, so that's when I tried disabling the BIOS
and installing ASPI4DOS /Paddress. When ASPI loaded, it said "Failed
scanning for SCSI devices" after a long wait.

So, any suggestions?

Oh yeah, there are no flashcodes being reported on the 1542's LED.
 
Don.
