This weekend, I experimented a little bit trying to put /etc/masterboot
at the beginning of /dev/hd00, but failed. Since I had prepared myself
for a full low-level reformat of the disk, I didn't try to hard and got
on with the low-level reformat. After that I reinstalled AIX and lo and
behold, it booted ok from the harddisk!
It seems doing a full backup, low-level format and restore was the
penalty I had to pay for even LOOKING at OS/2. Makes you wonder what the
penalty is for actually USING it :-)
Thanks to all the kind people who offered their advice on this one.
