VESA Connector
The Video Electronics Standards Association (VESA) defines a standard
video connector, variously known as the VESA
feature
connector,
auxiliary
connector, or
pass-through
connector. The integrated video
controller supports an output-only VESA
feature
connector. This connector
is integrated directly on the system board, and is connected directly to the
pixel data bus and the synchronization signals.
To use the VESA feature connector in DOS, or Windows 95, the FCON.EXE
utility must be executed. This utility configures the system.
WARNING
Use of the VESA feature connector will disable the 1 MB video
memory upgrade, if one is installed. Only the standard 1 MB of
video memory will be used.
