Felix....below are a couple of tables that might help.

Colors (depth) 640x480 800x600 1024x768 1280x1024 1600x1200
---------------+-------+-------+--------+---------+---------
256 ( 8 bit)| 769 771 773 775 796

The following table shows the mode numbers you can input at the VGA
prompt or for use with the LILO program. (actually these numbers are
plus 0x200 to make it easier to refer to the table)
Colours 640x400 640x480 800x600 1024x768 1152x864 1280x1024 1600x1200

Key: 8 bits = 256 colours, 15 bits = 32,768 colours, 16 bits = 65,536
colours, 24 bits = 16.8 million colours, 32 bits - same as 24 bits, but
the extra 8 bits can be used for other things, and fits perfectly
with a 32 bit PCI/VLB/EISA bus.
Additional modes are at the discretion of the manufacturer, as the VESA
2.0 document only defines modes up to 0x31F. You may need to do some
fiddling around to find these extra modes.
