Hello,
OK, booting from boot.flp, 2.1.5 CDROM distribution.  I have 2 HP scsi
disks (id 0 and 2) and scsi cdrom (id 2), and an ncr 53c810 pci scsi
controller.  The boot sequence detects the drives and prints the
manufacturers info, etc...

I get to the setup menu, go to create some partitons, and get a
message telling me I have no drives.

So I read the FAQ, find something regarding FreeBSD can't deal with
disk geometry translations, so use pfdisk.exe to 'tell' the
bios/contoller the real disk geometry.

I ran pfdisk and printed the geometry of one of the disks, 1019, 66,
63.  The HD manual says there are actually 3000 or so cylinders, not
1019.

My question is, after running pfdisk and changing the view my
controller has of the disk, what does this do to my data that is
currently on the disk.

Thanks,

Mark Crosland
