Probably, but we make no guarantees...

The pmax is little-endian, and the Amiga is big-endian, so you could
conceivably have some trouble, depending on exactly what you try to
do.   Certainly, you won't be able to use the Amiga newfs.   If we had
a net-bootable miniroot, I'd recommend using that, but we don't have
one yet.   As it stands, your best bet would be to dd legitimate boot
blocks onto the beginning of the disk, dd the miniroot from
dsg.stanford.edu on at block 16, and try to boot.

BTW, 100 megabytes is probably too small to do anything reasonable
with.   You might be able to configure a very minimal system, but if
you can come up with the bucks for a 500 meg drive, I'd recommend it
- you can live fairly comfortably one one of those, assuming that
you're keeping your source tree on your Amiga.

NetBSD/pmax doesn't have shared libraries yet - once it does, 500 meg
should be plenty for a full install plus a source tree, and 100 meg
installs might be possible.   Nobody's working on shared libraries
for pmax right now, though.
