I already did, but don't mind doing it again if it gets me closer to
understanding what's going on ...!
The motherboard is a micronics "mpower 4" with a 486DX-33 processor, 8MB of
memory, a localbus ide controller (the manual refers to an "on board super i/o
controller (smc 665)" but I'm not sure whether that is the ide controller or
not), localbus mach-32 video, Conner CP30254 240MB disk, 256kb external cache.
I've tried turning the cache from write-back to write-through and off
completely but I still see the errors.
The problem also happens on a machine with the same motherboard, but with
a 486dx2-66, 16MB of memory, and two Conner CP30344 340MB drives.

I have heard this is the case too. Can anyone name names...?
I have seen a news article somewhere that claimed that micronics motherboards
were pretty reasonable, but could well have been a different model, and anyway
was probably refering to it's performance running DOS...
I did try running the test perl script that triggers the problem under OS/2 on
the same hardware without seeing any problems, but I'm not sure that that
really proves anything.
