280000000 So I assume it has found the CD, and the install is usually
this size IIRC.

I assume this means there is only the CDROM on the channel? Thta would
be expected.

This translates to 280000000 bytes @ 512 bytes/sector.

oops. The read failed?

^^^^^^^^^^^^^^^^^^^^^^^^^^^
I think it is safe to say your problem is here. The other report had
the same thing.
The first offset is 3FFFFFFE, the second is 7FFFFFFC00, which is interesting.

This is a sideshow, I think. The reads failed and it's just running
with bogus data.

not even the read @ 0 worked. You've got a problem with BIOS I/O. I
wonder what it is?
