There are two files I have contained in the zip file you downloaded. First you will need to unzip these two files from the zip file. The two files contained are the reference drivers for a Voodoo Graphics card. These drivers should work with most Voodoo Graphics cards. Also included is the lastest copy of minigl for Voodoo cards. The setup of both is simple, simply run the program and it will install. Before you install the Voodoo reference drivers, make sure that you change your display adapter type to VGA and restart the computer. The file rkvg.exe is the Voodoo reference drivers, and the file miniinst.exe is the MiniGL file. Make sure you install the referenced drivers before the MiniGL drivers.
