  Note: The Infiniti Video Memory Display Adapter is configurable to work
  with 8 or 16-bit Video Memory Data Paths. If an 8-bit video memory is
  selected, an 8-bit BIOS is also selected. If a 16-bit data path is
  selected, the user can enable BIOS autodetect to automatically detect
  the proper BIOS setting. When the BIOS autodetect is disabled, an 8-bit
  BIOS is automatically selected.
