Very gratefule for all the good advice.Here's the story so far.
First of all, I was able to boot a 7.0 kernel with no difficulty - and
in the process discovered that there have been 2 CPUs all along. But
the disk layout is sorely in need of revision. So I have tried
everything I can find: in summary, cutting a new install image CD
failed to producenything that worked in the CD-ROM drive. I have a
2.02 install CD that goes into sysinst, but skips the disk layout
process and goes straight to installing sets. Other bootable media I
have don't boot in this drive. I do remember the days when CD-ROM
drives could be very fussy about CD-R and CD-RW media.
The 3.0 machine has a much saner disk layout - very possibly because I
configured it, whereas the 2.0 was configured by data centre staff way
back when. So I think I can move that forwad straightforwardly.
Is the disk layout configuration tool accessible other than through
running sysinst, or will I have to bite the bullet and edit the disk
label by hand? I think there is a sensibly sized root partition on
the 2.0 machine, so it might be possible to leave that untouched,
adjust the (insanely small) swap partition, and set up a sensible
layour for the rest of the disk while keeping a bootable root
partition.
All thoughts welcome.
