(Um, please be explicit about the model of your video card and the video mode which you are attempting to change to.) It is probably either your video card is not VGA (this is unlikely nowadays), or... The mode parameter table in your VGA card's ROM is not organized the way the console driver expects. There are unfortunately such cards out there. You can still use other functions of the console driver (such as mouse pointer), but can not change video modes. (X is OK, in case you are wondering :-) To verify if this is the case with your card, boot the system with the "-v" option at the "Boot:" prompt and check the output from the `dmesg' command afterwards. You will see "sc0: VGA registers upon power-up" followed by 64 bytes of hex dump. If you don't see another hex dump headed "sc0: VGA registers for mode:xx", the console driver found the mode parameter table of your VGA ROM strange and decided not to use it. Kazu PS: You will see "Invalid argument" error, if you have not loaded an appropriate font set for the new video mode. You need to explicitly load font sets other than the 16 line font (which is the built-in default of the VGA card). video mode required font -------------------------- VGA_80x25 16 line font VGA_80x30 16 line font VGA_80x50 8 line font VGA_80x60 8 line font EGA_80x25 14 line font EGA_80x43 8 line font
