Working with the Riva TNT video chipset
If you’re having problems with the Riva TNT video chipset, there are a few things you should check before giving up.
Look in your system’s BIOS for a setting called “video bios shadow.” Turn that off. Set your AGP graphics aperature size to 16mb. That should allow it to boot and work like a charm.
If after making the BIOS setting changes and installing the RIVA TNT driver, a blank screen still comes up, remember that [ALT + CTRL + SHIFT + F12] will restore the default resolution of 640 x 480 x8bpp, which you can then change to your preferred resolution.
