Thanks for the tip
After doing another manual reset of the monitor in sax2, i opened up xf86config and changed the sections on monitor, screen, card etc to what was in xf86config.sax2
on a reboot my settings were maintained and i had a very pleasant half hour in suse before my wife came home...
regarding non-modifyable cd rom, i'm sure this is true, but on installing it, a few files are created in C:\ and i guess the files are stored there.
cheers for the help!!
