hello,every one.
I need some documents about video card(such as how to use the video card ports and the general principle of video card driver),would you pls give me some links about this?
Thank you very much!

try out the VGA/SVGA section in Bona Fide (from .:QuickLinkz:.) ... but don't expect any low-level info for 3D accelerated card or high-resolution mode, because manufacturer don't provide it. high-resolutions (from 640x480x256 to 1600x1200x(16M+alpha) ) are available through the VESA bios extensions ...

Thank you very much,just the information I needed!
But you say:don't expect any low-level info for 3D accelerated card or high-resolution mode...
Does it mean that I can't accomplish high quality graphic representation(such as 3D) by myself?it means that the REAL video card driver can only be made by the manufacturer?

indeed ... except maybe for GLIDE (3DFX) cards for which i think some info have been distributed (as it dates from MS-DOS days where it was harder to distribute a separate driver) ...

having hardware-accelerated 3D graphics in an OS actually implies the support of a manufacturer-distributed driver by your OS. The only solution i can envision so far is the support of windows' drivers or linux drivers ...

note that there might be some interresting things to reuse from Linux drivers (ftp://download.nvidia.com/XFree86/Linux-x86/1.0-4363, for instance), for which the driver core is closed, but uses an open-source interface to Linux, so i guess it should be possible to replace the glu between the closed driver core and the linux kernel by another glu that would interface it with your own OS ...

not sure of it, though.

Alcatel drivers for SpeedTouch ADSL modem uses the same approach : closed driver and open-source GLU ...
