Re: PowerPC Debian install on IBM 43P boot problems...

there were two types of scsi controller on the 43P systems
the onboard is/was 53c810 which has a SE/LVD drive interface.
optional was 53c825 which is a HVD drive interface.
just check to see is any of the disks have the termination set on.
and there are termination resisters installed on drive (SE?)
(possibly terminator on and terminator power on)
there should only be one set on and it should be at the end of the scsi chain.
(drive address does not matter)
if no drives have the ability to terminate the scsi chain, then you need to get a
SE/LVD terminator and put it at the end of the chain.
 hope this helps

  Thanks for your reply.   Even though the SCSI disk partitioning went perfect and all partitions are fully initialized, and the base Woody (3.0) is installed, I still get this forever reported message at boot time:


SCSI host 0   abort   (pid 0)  timed out ? resetting

SCSI bus is being reset for host 0 channel 0

Ncr53c8xx_reset : pid = 0  reset_flags = 2  serial_number=(increasing numbers)   serial_number_at_timeout= (increasing numbers)


I have three disks (9 gig, 9gig, 17 gig) and a CDROM.  No external SCSI bus terminator is being used.  Should I add one?


  Thanks, and kind regards,

Dear all,


  I`m trying to revive an old IBM 43P for a customer into using it with Debian 3.0 (that`s the only version I was able to get bootable floppy images).


  After the successful partionning and installation of the base OS, during boot, it is stuck displaying infinite messages about the SCSI Controller 0, trying to reset it, and never ends.


  Has anyone been successful in such an installation on an old IBM 43P?
