Resolution too high, stuck out of windows server 2003

Hey, I have CSS Video machine that runs windows 2003 server, Pheonix AwardBios.
I need to get this thing up and running within a day or so, however the resolution is set to somthing far above what a monitor, HDTV, or projector can handle. So now I need to find a way to get it to come back to some thing lower.
No I can not get into safe mode or VGA mode, its not available for some reason. Yes I have a wired keyboard.
The question for me is, maybe there is another way to get into safe mode or VGA mode, possibly from a boot disk? Any help is appriectated.
