BootCD Problem - DVI - XHD3000

I've got a ATI 2400 Graphics card and just got a xhd3000 and I've got a problem. That I kinda solved but .... Let me break it down.

With the DVI interface while booting to a cd or a normal boot some screens of the booting process and the winxp load screen do not show but when I use the vga interface I can see every thing but when I get to windows I must lower the resolution to view the start menu so I need help


I want to use the DVI cable but I want to see every thing.

I thought I would need to update the driver in the video card but then I thougt that only windows uses that and has nothing to do with the bios so ... I'm stuck and need help thank for any input on the problem.
