Tried both ways - same result.

No. It does look strange, because it's booting from my main drive. But at
the boot stage NetBSD reports main drive as "wd1", instead of "wd0", as
usual.

Yes.

Yes. Unfortunately - as "wd0".

I'm afraid of messing a filesystem - it has different CHS translations on
the slow, and on the fast controller. Under Linux I could pass "chs"
parameter in the LILO boot-line. Not sure, it's possible under NetBSD.

You're right, never mind the transfer rate, I need just to transfer some
files, so I will survive - but the CHS translation does make it difficult.
