Hi,
Make sure you have the latest drivers – I just uploaded them and they may not
be available till Saturday. The file you need is VIB3DS.ZIP. Since there
already is a file called VIB3DS.ZIP, make sure you read the description to
confirm you download the latest one.
Also, make sure you are booting up without any CONFIG or AUTOEXEC when you are
trying to get the drivers to work with 3DS. We have had reports that some
files might interfere with the proper configuration and test of the driver
choices. 3DS4, for instance, should support your MGA card.
