oss653a: Initial VGA Recognition Supplement

Date Posted: 26-MAR-03

Brief Description: This supplement addresses the following problem:

Some systems incorrectly initialize the Primary Display Type bits in the CMOS Equipment Byte (0x14). This can cause OpenServer to incorrectly identify the video as CGA instead of VGA. OpenServer relies on reading the Primary Display Type bits to determine which video driver to use.

This can cause a variety of symptoms including:

  • Black or Blank screen
  • Invisible or unreadable fonts
  • Half letter fonts
  • Squished or Scrunched screen
