Re: Problem with Installation
I would suggest that you copy the necessary files from the CDROM to an
Amiga partition (under AmigaOS). Then retry the installation and specify
that the file are on the Amiga partition.
If this works then it is likely that you are experiencing a SCSI problem
1. The original SCSI spec did not specify timing requirement for
initialization sequences (and the Amiga SCSI is about the fastest
controller there is when it comes to initialization).
2. There are problems with many of the Western Digital SCSI chips used
in the Amiga's. These problem seem to crop up with certain drive
combinations and are usually worse with Linux than with AmigaOS.
3. There is (was?) a bug in the ROM code that initially identified the
drives on the bus. The Amiga made an incorrect assumption about the
size of one of the inquire responses and also did not "clean" the
response buffer. The result was that the controller initialization
code could use part of one drive's response in the configuration
information for a later drive. It was a rare problem because
usually the drive responses were the same length. I do not know
if this particular problem can affect Linux at all however since
I do not know if Linux retains any of the Amiga's initialization
data for the SCSI bus or not.
4. Your termination sounds right if the controller termination resistors
are also installed.
Although my experience was on an Amiga A3K and I used a MagOptical instead
of a CDROM, I had exactly the same behaviour.
