It was the geometry stuff that had me worried that vnconfig was not
what I wanted.

This did the trick - provided that the last number was correct.
See below.

This almost works (again with correct number of cyls) but I got lots
of read errors - 512/32/64/* works better.

I had no trouble testing my iso images on a 1.3.2 box.

The following script - saves having to remember anything :-)


# mntisofs isofs [mnt [vnd]] 

set -- `du -s -k $isofs`
Mb=`expr $1 / 1024`

vnconfig -vc $vnd $isofs 512/32/64/$Mb
mount -r -t cd9660 /dev/${vnd}a $mnt
