Hi :
I got a 1.3GB MO (SHARP JY-802MP) recently, but I can't get it
working under FreeBSD (2.2-960801-SNAP).
I partitioned/formated one side (6xxMB) under win95 and use it fine.
Then I boot into FreeBSD and type "fdisk od0", fdisk complains
"can't read partition table", and the disk geometry seems wrong.
The MSDOS partition disappear and a FreeBSD partition appears. :(
======= fdisk od0 =========
fdisk: Can't read fdisk partition table
******* Working on device /dev/rod0 *******
parameters extracted from in-core disklabel are:
cylinders=335 heads=117 sectors/track=57 (6669 blks/cyl)
parameters to be used for BIOS calculations are:
cylinders=335 heads=117 sectors/track=57 (6669 blks/cyl)
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 0 is:
<UNUSED>
The data for partition 1 is:
<UNUSED>
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
start 1, size 2234114 (1090 Meg), flag 80
beg: cyl 0/ sector 2/ head 0;
end: cyl 335/ sector 1/ head 0

Here is the verbose boot message

it complains "device od0 not configured", and console print:
