If a card fails setting mode with the vesa driver, the problem is not bugs in the vesa implementation, but rather non-protect-mode clean. As VBE3 is protected mode code, that problem should not exist. I know my STB 128 has VBE3 support. more importantly, Banshee which has no driver, and does not work with the current VESA driver has vbe3 support. >From what I heard most new cards has this. > With Windoze domination, there is no interest in supporting VESA > specifications, anymore.

It can be done easily (assuming its a .COM), or with many hardships (if its an EXE). Is there a reason to do it? > If SciTech(www.scitechsoft.com) will decide to support Linux sistems... > because with Windows, they have no more hopes to survive. There is an SDD for linux, but currently only X server in the beta they released. They promised svgalib support, so I still hope on that one. Now the question: how do I give a specific address in asm I want something like __asm__ ("sgdt &base") it does work with "sgdt 12345678", but how do I put there a variable?
