 DAC HIGH-RES PGA CARD

     We have customer reports of compatibility with this video adapter and
     Microchannel Above Boards.

     Tech Notes:
     This board uses 1K byte at address C600.  This address cannot be
     changed.  The DAC technical support phone number in the United States
     is ph (617) 439-0160.

 IBM 8514

     We have customer reports of compatibility with this video adapter and
     microchannel Above Boards.

     Tech Notes:
     This board uses addresses C680 to C7FF and CA00 to CA7F.  These
     addresses can't be changed.  If expanded memory is used, the expanded
     memory page frame could start at CC00.

 PARADISE VGA

     We have customer reports of compatibility with these video boards and
     microchannel Above Boards.

     Tech Notes:
     This board, with a ROM BIOS area larger than other Paradise boards,
     uses memory addresses C0000 to CBFFF.

 VGA MEMORY USAGE

     In general, VGA boards use the entire area from A000 to BFFF for video
     data.  VGA boards have several modes (for example, 640 x 480 with
     sixteen colors and 320 x 200 with 256 colors), but they frequently
     operate in EGA mode because few programs use true VGA capabilities.

     In ISA systems VGA boards use addresses C000 to C7FF, which in effect
     is an extension of EGA (EGA uses addresses C000 to C3FF).  Most ISA VGA
     boards reserve, though not necessarily use, addresses from A000 to
     C7FF.

     In Microchannel systems, IBM's standard PS/2 VGA doesn't occupy the
     C000 to C7FF area because the BIOS supports it directly.

 VIKING PS/2 VIDEO ADAPTER

     We have customer reports of compatibility with this video card and
     Above Boards.

     Tech Notes:
     This is the adapter for the Viking Moniterm high-resolution, full-page
     monochrome monitor.  It uses a ROM address space of 16K bytes that you
     can set for any 16K-byte interval starting at address C000.  These are
     the available addresses:

                    C000-C3FF            D000-D3FF
                    C400-C7FF            D400-D7FF
                    C800-CBFF            D800-DBFF
                    CC00-CFFF            DC00-DFFF

     This board is reported to use DMA Channel 6 and I/O Port address 3E8.
