******* Working on device /dev/da4 *******
parameters extracted from in-core disklabel are:
cylinders=1440 heads=210 sectors/track=13 (2730 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=1440 heads=210 sectors/track=13 (2730 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 165,(FreeBSD/NetBSD/386BSD)
start 0, size 3933040 (1920 Meg), flag 80 (active)
beg: cyl 0/ sector 1/ head 0;
end: cyl 244/ sector 13/ head 209
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>
