I am trying to install FreeBSD on a compact flash drive. The drive manual
says the drive geometry is 250880 sectors, 8 heads, 32 sectors per track,
and 980 cylinders. The BIOS for the computer reports drive geometry as
980/8/32 C/H/S.
I read somewhere that this problem generally indicates a drive geometry
problem. I do believe I have my geometry correct. I am obviously missing
something. I followed the instructions for miniBSD for the most part.
Any other ideas on what could be causing this error? Gorey details
below.

My disktab entry is:
sd128:\
:dt=ESDI:\
:ty=winchester:\
:ns#32:\
:nt#8:\
:nc#980:\
:pa#250880:oa#0:ba#8192:fa#1024:ta=4.2BSD:\
:pc#250880:oc#0:bc#8192:fc#1024:tc=unused
I use the commands...
disklabel -Brw vn0 sd128
newfs -T sd128 -U /dev/vn0a
...to label and newfs the disk.
fdisk /dev/vn0c reports:
******* Working on device /dev/vn0c *******
parameters extracted from in-core disklabel are:
cylinders=980 heads=8 sectors/track=32 (256 blks/cyl)
parameters to be used for BIOS calculations are:
cylinders=980 heads=8 sectors/track=32 (256 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
