Oh is this really neccessary?
From one of my i386's:
# /dev/rwd0d:
type: ST506
[...]
7 partitions:
# size offset fstype [fsize bsize cpg/sgs]
a: 47376 0 4.2BSD 1024 8192 16 # (Cyl. 0 - 46)
b: 201600 47376 swap # (Cyl. 47 - 246)
c: 16406208 0 unused 0 0 # (Cyl. 0 - 16275)
d: 16406208 0 unused 0 0 # (Cyl. 0 - 16275)
e: 2119824 248976 4.2BSD 1024 8192 16 # (Cyl. 247 - 2349)
f: 6199200 2368800 4.2BSD 1024 8192 16 # (Cyl. 2350 - 8499)
g: 7838208 8568000 4.4LFS 1024 8192 7 # (Cyl. 8500 - 16275)
NetBSD disklabel disk geometry:
cylinders: 16276 heads: 16 sectors/track: 63 (1008 sectors/cylinder)
BIOS disk geometry:
cylinders: 1021 heads: 255 sectors/track: 63 (16065 sectors/cylinder)
Partition table:
0: <UNUSED>
1: <UNUSED>
2: <UNUSED>
3: sysid 169 (NetBSD)
start 0, size 16 (0 MB), flag 0x80
beg: cylinder 0, head 0, sector 1
end: cylinder 0, head 0, sector 16
And it boots real fine^TM (from that harddisc)...
Same is true for two other i386 (but with SCSI) and my laptop.
Why should I waste ~30 valuable kilobytes? My first computer didn't had much
more memory and I was able to do a lot with it :-)
