I just purchased a zip drive to use on my Mac IIci with NetBSD and
am having some problems.  I followed the How-To (using silver lining
for partitioning) and managed to get illegal instruction traps over
and over again.

One question about the How-To, it has 6144 blocks for eschatology
which I thought we didn't need?  Also, I am planning on using the
disk for backups and archiving some old stuff so am I correct in
assuming I also don't need the swap partition either? (I guess thats
actually 2 questions).  Anyway, I have tried both the #'s from the
How-To and also

194036 blocks for A/UX Root&Usr Slice0
with the rest for HFS.

Mkfs (1.45) seems to run ok, I have tried the How-To numbers
(using the appropriate number for file system size) and also
tried what ever defaults came up.

When I boot NetBSD (single user)

NetBSD 1.3_ALPHA (GENERIC) #48: Fri Nov  7 16:25:23 PST 1997

^^^ This is with the zip ejected.  With the zip in, I get 96MB, 96cyl, 64heads,32sectors

Then 
disklabel sd2

prints out some of the right stuff, but gives a kernel panic (illegal instruction
trap) at about the point where the prompt should come back.

fsck -f /dev/sd2a

gives a kernel panic. after making it to the point of "marking file system clean"

newfs /dev/sd2a

gives a kernel panic. towards the end (after listing where the super block
backups are).

I will try and upgrade to 1.3beta to see if it fixes, but I had really hoped
to get the zip working so I could download 1.3beta at school and bring it home
on the zip instead of using my 14.4 modem to get it.

Anyone else have problems (or success?)?
