BIOS support for DVI

5 posts in this topic

I have an older motherboard from 2003. I've always used VGA for my monitor. Recently, my CRT monitor started showing signs of failing, so I was forced to buy an LCD monitor. The LCD monitor supports only DVI-D. I also had to buy a video card with a DVI-I port. Does the BIOS have to support DVI in order for the monitor to show the BIOS and boot-up screen? Or will my BIOS and boot-up screen show fine as long as my AGP graphics card doesn't have an issue? I don't want to run into trouble with the new monitor. All the quality LCD monitors use DVI-D, so I had to accept this forced upgrade.

I just want to be sure there's no gotchas since my motherboard is older and DVI is newer.

VERY simplified:

Your motherboard "talks" PCI or AGP (or PCIE)

*Any* video card "talks" either of PCI or AGP (or PCIe) internally and either of VGA, DVI, Video, S-Video etc. externally.

As long as you have drivers for the video card suitable to your OS, you are good to go, the BIOS sends *something* to the *whatever* bus, and the video card "translates" this *something* to *whatever* the video card is supposed to output, *any* video card is "compatible" with the *whatever* the motherboard sends through the bus (usually 80x25 text screen or low resolution frame buffer).
