> functions inside via_ums.c. In particular, made sure
> that UniChrome Pro or later graphics will all run
> through a certain code path within the function.
> Previously, some chipsets with UniChrome Pro or later
> graphics were going through the code path meant for
> UniChrome graphics.     The compiled device driver
> was tested on the following computer.
