Very Computer

- UDB 166 w/ 32 MBytes of  DEC parity RAM. No floppy. External DEC RZ26
1Gbyte disk
- CD drive was borrowed from a DEC Alpha I have running VMS
- RedHat 6.2
- CD-ROM booted w/ command boot dka500 -fi /kernels/generic.gz -fl
root=/dev/scd0

After the point in the boot process where unused kernel memory is freed I
get this.

SCSI : aborting command due to timeout: pid 55, scsi0, channel 0, id 5, lun
0 0x28 00 00 14 24 d0 00 001000
ncr 53c8xx_abort: pid=55 serial_number=61 serial_number_at_timeout=61
SCSI host 0 abort (pid 55) timed out - resetting
SCSI bus is being reset for host 0 channel 0
ncr53c8xx_reset pid=55 serial_number=61 serial_number_at_timeout=61
ncr53c810-0: restart (scsi reset)
ncr53c810-0-<5,*>: device did not report sync
sro: CD-ROM not ready. Make sure you have a disc in the drive
CD-ROM i/o error
Kernel panic: No init found

Should I just buy a floppy drive for this thing and install that way?  Any
others ideas?

Thanks,
Bob

Sorry for the double original post folks.  Usually my news server shows post
within minutes.  After 90 minutes, I didn't see the first one so I fired
another one off.

Gotta cut down on the caffeine. ;-)

Hope this helps.

Linux kernel does not have preassigned IDs for things like tape or CD.
Devices are scanned on boot.

There are older drives which has distinct problems with reading CD-RWs
(different reflectivity) and especially if there is more than 600 MB of
data on a disk.  And really often cables and terminations ARE the
problem.

Now that's interesting... this *could* be my problem.  I'm using a very old
DEC 1x or 2x CD player.  It's the only external one I have.  Me thinks I
will have to borrow a more recent vintage internal drive and try it.  Of
course I'll also have to figure out where to get 5 volts off the Multia/UDB.
