Hi - recently, I acquired an Ultrastor 34F (local-bus SCSI) to replace
my Adaptec 1542 (which is going into my non-LB machine). I've had the
devil's own time getting it to the point where I can boot Linux (most
problems were due to my motherboard not supporting bus-mastering, but
that's another tale).
At any rate, it now recognizes the SCSI chain, and everything on it.
I'm having the following problems (and, yes, my PL10 kernel is
configured to support the Ultrastor family of boards):
PL10 hard disk boot:
LILO gets out "LI" and hangs, sometimes with colorful garbage on
the screen
PL10 floppy disk boot:
LILO loads the (compressed) kernel just fine, and finds the
character devices. Then I get the following series of messages
(obviously from the filesystem determination attempts):
SCSI disk request error: invalid device
ll_rw_blk: trying to read non-existent block_device 0801 (1)
MINIX_FS - unable to read super_block
SCSI disk request error: invalid device
ll_rw_blk: trying to read non-existent block_device 0801 (1)
EXT_FS - unable to read super_block
SCSI disk request error: invalid device
ll_rw_blk: trying to read non-existent block_device 0801 (1)
EXT2_FS - unable to read super_block
SCSI disk request error: invalid device
ll_rw_blk: trying to read non-existent block_device 0801 (0)
MSDOS bread failed
SCSI disk request error: invalid device
ll_rw_blk: trying to read non-existent block_device 0801 (32)
isofs_read_super: bread failed, dev 0x801 iso_blknum 16
kernel panic: VFS: unable to mount root
*However*, PL5 boots from floppy just fine and comes up. So, I'm
quandarized. I'm about to leave for about 4 hours, and I'm hoping
some kind soul out there has some ideas/pointers on what to try. I'd
really like to get this to work, as I have other plans for the
Adaptec. And I'd really like to keep the Linux machine local-bus, as
it's my main machine for doing lots of things at once.
Thanks in advance. Please respond to me directly to save net.bandwidth.
I'll summarize/remail if there's interest.
Bob
