Message-ID: <3B3A7E3D.394759D6@blueyonder.co.uk> (raw)
I attached an external SCSI disk to my 712/80 which has the
palinux-0.9 32 bit serial distribution installed on the internal
disk:
BOOT_ADMIN> sea
Searching for potential boot device.
This may take several minutes.
To discontinue, press ESCAPE.

scsi.6.0 QUANTUM FIREBALL1050S
scsi.2.0 SEAGATE ST32151N
BOOT_ADMIN> boo
Can anyone guess what happened next?

VFS: Cannot open root device "sda3" or 08:03
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 08:03
The code in drivers/scsi/sd.c assigns /dev/sda to the lowest SCSI
id and works up the way. Fair enough. IIRC SCSI id's are prioritised
7->0 for narrow SCSI and 7->0, 15->8 for wide. Should device allocation
reflect this pattern? Surely it has to for hppa where the internal
disk has id 6 preset?
Any suggestions?
Cheers
Donald
