- In order to answer this question, I need to know what version of LINUX you
- are running? When LINUX boots, do you see a line indicating VESA support
- in your video card? Followed by your video mode choices? If so, then
- when you select a mode, LINUX make a VESA BIOS extension call to set your
- video mode. If it fails, then there is a problem with your video card.
-
- My card gives me 4 choices. The first two are hard coded (80x25, and 80x50)
- and appear in EVERYONE's VESA list. 80x25 is the standard MODE-3, while
- 80x50 is the same mode with an 8x8 font loaded instead of the default 8x16
- (or 8x14) font. The rest of the modes in the list come from the VESA modes
- list returned by the Get VESA information call. On my card they are 132x25
- and 132x43. These modes both work for me.
-
- IF you are running version 0.96c at patch level 1 or greater and
- IF YOU DO NOT HAVE A VESA BIOS, or
- IF you are running any version before 0.96c-pl1, then you get a list of
- "standard" modes put up specific to your video card,
- which for a Trident card would be: 07, 50, 51, 52, 57, 58, 59, and 5A
- which are 80x30, 80x43, 80x60, 132x25, 132x30, 132x43, and 132x60. These
- are stadard Trident Video modes, and are set by an INT 10 video bios call
- to the Set Video Mode function using the mode number from the list.
-
- Unless I have screwed up the old functionality badly with the VESA support,
- which you can check by building a LINUX kernel with an old boot/setup.S
- file, then your mode set call is failing and you possibly have a faulty
- video board. I'll double check the compatibility code when I get home
- tonight, but I would have thought that there would have been more complaints
- by now if I broke the old stuff.
-
- Please let me know if I can be of any more help.
