Since you asked :-)
bra@BAPhD ~ #fdisk /dev/ad0
******* Working on device /dev/ad0 *******
parameters extracted from in-core disklabel are:
cylinders=3D1027 heads=3D255 sectors/track=3D63 (16065 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=3D1027 heads=3D255 sectors/track=3D63 (16065 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 6,(Primary 'big' DOS (> 32MB))
start 63, size 2056257 (1004 Meg), flag 80 (active)
beg: cyl 0/ head 1/ sector 1;
end: cyl 127/ head 254/ sector 63
The data for partition 2 is:

beg: cyl 128/ head 1/ sector 1;
