Yup, here you go

parameters extracted from in-core disklabel are:

Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=2020 heads=128 sectors/track=32 (4096 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:
<UNUSED>
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
sysid 165,(FreeBSD/NetBSD/386BSD)

beg: cyl 0/ sector 1/ head 0;
end: cyl 1023/ sector 63/ head 255
Hmmm... This last bit looks odd.
