At least, that's what my experience suggests (and I'm sure I read it in either the Hitchhiker's Guide to the BIOS or in ST Internals). I have a feeling that you will have to directly manipulate the screen address register (listed in ST Internals, and probably elsewhere). -- - Jonathan Fischer (jafischer@watrose) or: watmath!watrose!jafischer or: jafischer%watrose@waterloo.csnet or: jafischer%watrose@waterloo.csnet@csnet-relay.arpa
