When you install Windows NT 4.0, the STB PowerGraph Video VLB adapter in your computer may be detected as a VGA-compatible display adapter.


The STB PowerGraph Video VLB adapter uses an S3-765 chip set. This chip set is supported with Windows NT 4.0 only on a PCI bus.


Windows NT 4.0 installs and uses the VGA-compatible display driver and functions correctly, but you cannot use any of the performance advantages of the display adapter.
