Well,
I have discovered that I am very confused on how FreeBSD handles its
boot stages... Now I have managed to hose the drive to the point that
it will not boot with drives on either controller.
I did did a boot0cfg -B on both drives and then moved them to the new
controller and rebooted. I get to the first two stages fine:
>> FreeBSD/i386 BOOT
Default: 0:ad(0,a)/boot/loader
boot:
I can issue the following:
boot: 0:ad(0,a)/boot/?
and see the listing of the files including loader.
However, once the loader tries to go my machine hangs with the following:
BTX loader 1.00 BTX version 1.01
Consoles: internal video/keyboard
BIOS drive A: is disk0
BIOS drive C: is disk1
BIOS 640kb/490432kB available memory
FreeBSD/i386 bootstrap loader, Revision 1.1
(root@x64.samsco.home, Thu Nov 3 07:33:10 UTC 2005)
-
And the machine goes no further...
At this point I have pulled one of the mirrored disks so hopefuly in
the process of learning whats going on I keep one valid drive.
I can boot with fixit CDROM and mount the drive and see all the data
is fine and dandy, just cant boot.. Seems there is a config issue with
the loader??
Any help would be appreciated! Im pulling my hair out reading the man
pages trying to figure this out...
Thanks,
Brent
