 PACKARD BELL 1518 FULL PAGE DISPLAY

     *FIELD REPORTS* of compatibility with Above Boards.

     Tech Notes:
     This board uses addresses A0000-AFFFF and B0000-C7FFF, which might be
     an issue if the Above Board is providing expanded memory.

 PARADISE

 PARADISE EGA AUTOSWITCH BOARD

     *FIELD REPORTS* of compatibility with Above Boards.

     Tech Notes
     Paradise tech support {ph: (800) 356-5787} supplied the reserved memory
     addresses this EGA uses. Memory Address: A0000 - C3FFFF

     NOTE:  If a memory size error occurs during IBM Setup program, try
     disabling the "AUTOSWITCH" feature of the PARADISE board, temporarily.
     There is a 5 position switch on the board to do this.  After completing
     the SETUP program, it can be re-enabled.

 PARADISE MONOCHROME AUTOSWITCH

     *FIELD REPORTS* of compatibility with Above Boards.

     Tech Notes:
     This board is apparently able to emulate an EGA or CGA board, as well
     as operate as a monochrome adapter.  It has ROM from C0000-C3FFFh, just
     like an EGA board, and uses the A0000-BFFFFh spaces for Video Ram.

 PARADISE MODULAR GRAPHICS BOARD

     *FIELD REPORTS* of compatibility with Above Boards.

     Tech Notes: One customer report that this board uses C0000 to C4000
     memory addresses.

 PARADISE VGA (8-BIT BOARD)

     Compatible with Above Boards.

     Tech Notes:

     Has ROM BIOS addresses C0000-C7FFFh.  This is an 8-bit board that works
     in PC/XT machines as well as AT machines.  It has no conflicts with the
     AB products except the addresses occupied by the BIOS, as noted above.

 PARADISE VGA PLUS 16

     *FIELD REPORTS* of compatibility with Above Boards.

     This board can be operated with the BIOS configured for either 8-bit or
     16-bit modes. The PARADISE manual clearly states that you cannot
     operate this board in the 16-bit mode if you have ANY other boards that
     have RAM or ROM in the C0000-DFFFF address range.  This board needs to
     be set for 8-bit mode if the Above Board is supplying any expanded
     memory.

     To set this Paradise board to 8-bit mode, move jumper W1, (located in
     the lower left corner of the board), so that it covers BOTH PINS.
     Additionally, SW1-4 on the switch block must be set to the OFF position
     to force 8-bit operation.

     Appendix B (pp 42-44) in the Paradise manual explains the restrictions
     in detail. Urge the customer to read this section if they are unhappy
     about having to put their VGA board in 8-bit mode.

 PARADISE VGA PROFESSIONAL 16 BIT

     Compatible with AB.  BIOS occupies C0000-C7FFFh.  AB will conflict with
     the VGA in 16 bit mode.  Put VGA in 8 bit mode by setting switch #4 to
     the OFF position.  Performance is not hurt because Paradise provides a
     caching feature for the ROM BIOS.

 PARADISE 8514

     Field report of compatibility with Above Boards.

     Tech Notes:
     8514 uses ROM @ C8800-C9FFF or D8800-D9FFF.

 PARADISE VGA 1024

     Field reports of compatibility with Above Boards.

     Tech Notes:
     Paradise manual says if using EMS board, place BIOS jumper 1 over both
     pins. Summary of Paradise manual Appendix B switch settings:

     Switch 4 on switch block allows selection of 8 bit mode  To force 8 bit
     mode: cover both pins of Jumper W1 and set switch 4 OFF  switch 4 ON
     lets the board automatically choose 8 or 16 bit. Jumper W1 controls
     automatic versus manual selection of 8 and 16 bit mode.  Both pins
     covered = automatic  One pin covered = manual (forces 16 bit always)

 PHOTON ULTIMA TURBO VGA

     *FIELD REPORT* of compatibility with Above Boards.  The Photon Ultima
     Turbo VGA is by Personal Computer Graphics Corp.  Tech support ph.
     (213) 216-0042.

     If you are using EMM.SYS for expanded memory, EMM.SYS will require the
     "16BIT=" parameter.  You must have EMM version 4.0 rev C, (disk label
     dated 5/89) or later.  For more information on the "16BIT=" parameter
     see the "16BIT=" Scoop Cell.

 QUADRAM

 QUADRAM COLOR PALLETTE

     Incompatible with ALL memory boards providing expanded memory, although
     it may work if providing extended memory.

 QUADRAM QEGA PLUS

     According to customer report, this EGA board is incompatible with
     Expanded memory.  ABs can provide conventional and extended memory in a
     machine equipped with this video board.

 QUADRAM QUADSTREAM

     *FIELD REPORTS* that this video adapter is INCOMPATIBLE with Expanded
     memory.
     Uses Hex addresses C0000-E0000 so AB has no place for page frame. Above
     Boards can provide conventional and extended memory in a machine
     equipped with this video card.

 RENAISSANCE

 RENAISSANCE RENDITION I

     The Renaissance Rendition I plus graphics engine is compatible to AB
     products. Renaissance makes extensive use of EMS memory so it is
     recommended that the user have LOTS of EMS.  Uses memory range A000-
     C400.

 RENAISSANCE RENDITION II

     *FIELD REPORTS* of compatibility with Above Boards.

     Tech Notes:
     The Renaissance Rendition II is a 16 bit board.  This board must be set
     for 8 bit reserved memory accesses in order to work with an AB.
     Renaissance makes extensive use of EMS memory so it is recommended that
     the user have LOTS of EMS. Uses memory range A000-C400 for ROM and C800
     and up for shared RAM. The Rendition user manual has a section on
     installing with the Intel AB.

     Tech Support ph: 800-422-7369

 RENAISSANCE RGX VGA

     **Field report** of compatibility with Above Boards. NOTE: the 16-bit
     ROM feature on the RGX VGA has to be disabled when the RGX VGA is
     installed into a 16-bit slot and an Above Board is set up for EMS.

     This is necessary because the RGX VGA doesn't do a true 16bit reserved
     memory access, it fluctuates between 8- and 16-bit accesses. If it did
     a true 16bit access there wouldn't be a need to force it into 8bit
     mode.

 VGA MEMORY USAGE

     Some general info:

     VGA's in general use ALL of A0000 to BFFFF for video data. These guys
     tend to be in EGA mode most of the time because software has to be
     rewritten to use REAL VGA capabilities. There are more and more REAL
     VGA applications being written daily.

     VGA mode itself has several modes i.e. 640 x 480 w/sixteen colors, 320
     x 200 w/256 colors (WOW the shading) and some others.

     The VGA board has TWO eproms located at C0000 to C7FFF which in effect
     is an extention of EGA (EGA used C0000 to C3FFF) so we can forget about
     the lower half of the C0000 area for use when providing expanded (LIM
     EMS) memory.

     Most VGA boards occupies (not necessarily always uses) the area from
     A0000 to C7FFF (160k!).

     IBM 's VGA in the PS/2 machines don't occupy the C0000 to C7FFF area
     because the BIOS supports it directly.
