mmm, ESDI

Hmm.. Might be, but if you have a (wd front-end?) ethernet card that
isn't configured as the INSTALL says, it's probably that.  I didn't want
to rejumper mine, so I just lived with the messages until I recompiled
a custom kernel to match it.

Cyrix or IBM "Blue Lightning" CPU?

hmm.. you might try turning off the cache on your controller card.

Also, I don't know if it would make a difference, but have you tried giving
NetBSD the `remapped' drive parameters?  I don't think the params are used
for anything but disktab(5), but it's a shot-in-the-dark.  (help?)

As for DPT, I have no idea (I didn't know they manufactured ESDI cards).
I'm running an Adaptec ESDI controller card, and love the thing.  No cache,
though.
