The gx_vesa driver comes in four different modules.
gx_vesa is the normal one. It has 640x480, 800x600, 1024x768, and
1280x1024 support at 256 colors. The VESA BIOS is asked what
modes are supported. The BIOS should stop the driver from setting any
modes that can’t be displayed. This driver will use a linear display buffer
if the VESA BIOS is version 2.0 or greater and tells the driver that linear
buffers are supported.
gx_vesal will only work on cards with BIOS’s that support linear mode. It
is about 3 times faster than gx_vesa on supported hardware.
gx_vesah adds support for 15 bit high color modes. It looks for the
highest resolution high color mode. The color depth table is separate
from the resolution table.
gx_vesalh is a linear buffer only with high color support.
The descriptor is vesa and there are two cdb’s. cdb_vesa and
cdb_vesa_s. cdb_vesa is set up for a bus mouse and cdb_vesa_s is set
up for a serial mouse.
The gx_isabank driver comes in three modules depending on what
default resolution you want. gx_isabank1 has a default of 1024x768,
gx_isabank6 has a default of 640x480 and gx_isabank8 has a default of
800x600 all at 256 colors. The gx_isabank driver uses a data module to
tell it how to talk to different hardware. The data modules include are:
