Multi displays - onboard and seperate?
 

If you are running XP or 2K.... Set the PC to boot off of the AGP card,
and
when in Windows, set the PCI card to the primary in the display properties
dialog.

Good idea, unfortunately as soon as windows boots up win2k), the monitor
switches itself off - maybe its loading the wrong drivers - which I can't
really control. The other display remains switched off...
