Rescuing an MS-5185 Super-Socket 7 board with on-board ATi Rage PRO and Creative Audio-PCI

We are repairing a Gateway MS5185 motherboard based on the ALi Aladdin V chipset, that has both an ATi Rage PRO Turbo AGP graphics chip with 8MB of RAM and a Creative ES1373 Ensoniq PCI audio chip on-board.
Then we are trying out a few DOS games, including Duke Nukem 3D, Jazz Jackrabbit, Quest for glory Shadows of Darkness, and Monkey Island.
We are also adding the unpopulated ISA slot along with its 74ALS245 transeiver chip, and testing an OPTi 82c931 sound card.
We are also testing 3D Mark 99 and 2000 on a K6-2+ 550Mhz.
