Okay. I did that. It doesn't work as for a 80 Gb hard disk, but
it works for a CD-R/W.

Well. I have been experimenting and a Firewire CD-R/W is found and
accessible. However, a 80 Gb Maxtor hard disk is not. I had to
copy from an RS-232C screen because the resounding crash(es) repeat
forever until I hit the reset switch. <EOL> == "end of line with
data missing after".

Startup messages continue without further references to either SCSI
or IEEE1394. The crash occurs when my SCSI root-file system is first
referenced after initrd completes (pivot_root).
When this 80 Gb drive is used under W$, on the same machine, I see
no evidence of "GHIJKLMN" or "OPQRSTUVWXYZ" although the device-manager
doesn't let you read physical device info like it does with SCSI.
Number 24, shown above, is ^X, not part of the obvious
"ABCDEFGHIJKLMNOPQRSTUVWXYZ" string that we see parts of above. So
it doesn't look like a read from the wrong offset during the device-
inquiry.
I'm using Linux-2.4.18. Maybe there is a more "mature" version
of sbp2 I should be using??
