Why do I get the feeling that what you REALLY want to do is to go out and
buy yourself half a dozen 2GB drives?

I have some Microp's here which work just fine. I follow one of the normal
conventions and force fdisk to use X/64/32 geometries..
******* Working on device /dev/rsd10 *******
parameters extracted from in-core disklabel are:
cylinders=8681 heads=64 sectors/track=32 (2048 blks/cyl)

sysid 165,(FreeBSD/NetBSD/386BSD)
start 32, size 17778656 (8680 Meg), flag 80
beg: cyl 0/ sector 1/ head 1;
end: cyl 1023/ sector 32/ head 63
I always start at sector 1 head 1, end at 32/63

That bsize looks a tad wild.

8 partitions:

e: 17778656 0 4.2BSD 0 0 0 # (Cyl. 0 - 8680*)
This is a bit different, usually I start 'e' at cylinder 1 and end at the
last full cylinder (i.e. Cyl. 1-8679)
