Well, I've determined that everything works fine under ms-dog so
it isn't the cable.  :)  However it still doesn't work under
386bsd.  :(

Would some kind soul with a 1542C tell me *exactly* how they have
it set up?  It was suggested that it may be a CPU cache problem
but I first disabled the external, then the internal and it
didn't have any effect.  

[For those who missed the original post, I've got a Adaptec 1542C
and Quantum P105s (among others) that I'm trying to get working
with 386bsd.  I'm using the 0.2.3 patched GENERICISA kernel from
agate.  Disk i/o get terribly mangled most of the time.  On two
occasions I got a kernel panic (and die).  I'm booting off an ide
drive that works fine.  The machine is a 486dx33 with 8 meg of
ram and a 256k external cache and vl-bus.  BIOS is AMI.
According to the little booklet, the motherboard is a UM 486V AIO
if that means anything to anyone.]
