I'm trying to install 386bsd (the distribution kit) on my home
machine, a 486DX 33Mhz clone, ISA bus and a LomgShine LCS-6631(F)
SCSI controller emulating a WD 1003/1006.

My installation disk is a Fujitsu M26225-512 320Mb, that my
controller see as a 731 cyl, 16 tracks, 55 sectors (I checked
with pfdisk). On this disk there is already a DOS partition
going from Cyl 0 to Cyl 311 (for 134Mb).

There is something of geometry remapping going on in the
controller, but I think (from other OS experience) that
is completely masked to the SW.

The dist.fs boot weel and the install program finish fine,
installing 386BSD on a 180Mb partition going from Cyl 312
to Cyl 730 (the 386BSD part is the 4th in the MBR if I
remember correctly).

When I try to boot from HD, 386BSD come up, but saying that 
it is unable to mount the root and obviously it panics.

OK. I checked the partition using the fixit diskette and
disklabel. Using disklabel I discovered that the label
have wrong block labels and the geometry is wrong (1024 Cyl,
instead of 731). I relabeled the disk using disklabel and
the correct geometry and I was able to mount /dev/wd0a from
the fixit diskette. 

At this point I thaught I found the problem, but at the next
boot again paning. Rebooting the fixit and the label was
again wrong.

What may be a correct strategy to install 386BSD on my system?

Thank in advance,  Peppe
