AST PREMIUM 386

  *CUSTOMER REPORTS* that this 80386-based computer is compatible with Above
  Boards and Matched Memory Classic.  Customers report that this system has
  a standard 8MHz data bus and the discontinued Above Board AT and PS/AT and
  Above Board 286 are also compatible.

  If an AST Extended Memory board is being used, it must be completely
  filled, (4Mb), before any EXTENDED memory can be added by any other memory
  board.

AT&T 386 EWGS

  *CUSTOMER REPORTS* of compatibility with current Above Boards and Matched
  Memory Classic.

  Tech Notes:  This is an 80386-based system that has an option ROM at
  address DE000 that apparently cannot be moved.  If an Above Board or
  Matched Memory Classic board is being used to supply expanded memory, be
  sure the page frame does not overlap the option ROM address.

AT&T 386SX WGS

  *CUSTOMER REPORT* of compatibility with current Above Boards and Matched
  Memory Classics in this system.
  Tech Notes:  This system apparently has 384K reserved for system use.  The
  reported system had 2Mb on the system board and it was necessary to set
  the Above Board extended memory starting address to 2048K.

AT&T 60-386

  *CUSTOMER REPORT* of compatibility with Above Boards and Matched Memory
  Classic.

  Tech Notes:  This is 16MHz 80386SX-based system.  There is 1Mb on the
  system board, 640K conventional and 384K of "DEDICATED MEMORY".  The
  Dedicated Memory can be set up as Shadow RAM but doesn't have to be.  When
  setting up an Above Board or Matched Memory Classic board for extended
  memory, make sure the Dedicated Memory is set up for shadow RAM and that
  RECLAIMED MEMORY is set to ZERO.  At this point, run SETBOARD and set the
  extended memory starting address to 1024K.

COMPAQ
COMPAQ DESKPRO 386/16

  Compatible with current Above Boards and Matched Memory Classic.  Also
  compatible with discontinued Above Board 286, PS/286, AT and PS/AT.

  Tech Notes:  System has 1Mb of memory onboard.  It is configured as 640K
  conventional, 256K extended, and 128K reserved for system use.  It also
  has sockets for an additional 1Mb of extended memory, (address 1.0M to
  2.0M), which should be filled before using an Above Board or Matched
  Memory Classic for additional extended memory.  The 256K of Compaq
  extended memory,  (from the first 1Mb), will be automatically addressed
  AFTER other extended memory in the system.  This allows an Above Board or
  Matched Memory Classic to have an even starting address boundary, (i.e.
  2.0M).

  System comes with an expanded memory emulator called CEMM that makes the
  system's extended memory look like expanded memory to programs like Lotus
  123 Rel 2.x.  You cannot use both Compaq's CEMM and EMM, (Intel's expanded
  memory manager), at the same time.  You must either configure the Above
  Board or Matched Memory Classic for expanded memory and use EMM only, or
  you must configure the board for extended memory and use CEMM, (or some
  third party 386-control program).

COMPAQ DESKPRO 386/20

  Compatible with current Above Boards and Matched Memory Classic.  Intel
  has also tested the discontinued Above Board 286 & PS/286 in this system
  and they worked fine.  Customers have reported that the Above Board AT and
  PS/AT do not work reliably.  This computer operates an 8MHz bus.

COMPAQ PORTABLE 386/20

  LIMITED COMPATIBILITY with Above Boards and Matched Memory Classic.  In
  order to use an Above Board or Matched Memory Classic in this system, the
  system must have 2Mb of memory on the motherboard and the Above Board or
  Matched Memory Classic must be configured as extended memory.

  Details:
  The Compaq Portable 386 comes with 1Mb, which is set up as 640K
  conventional, 128K to "shadow" the ROMs, and 256K as "additional built-in
  user memory."  This last 256K is extended memory, but it is placed just
  below the 16Mb boundary so normal programs, (excepting CEMM), cannot find
  it.

  If an Above board or Matched Memory classic is installed while the
  motherboard only has 1Mb, it will not work.  TESTAB will show all chips
  bad, EMM will not find any expanded memory to manage, and extended memory
  will not show up.

  If the 1Mb Compaq upgrade, (two proprietory-looking 512K SIMMs), is
  installed, then any extended memory on an Above Board or Matched Memory
  Classic will work fine.  The jumpers in the Compaq should remain set on
  2Mb regardless of the amount of memory on the Above Board or Matched
  Memory Classic

COMPAQ 386/S (80386SX MACHINE)

  Compatible with current Above Boards and Matched Memory Classic.  The
  discontinued Above Board 286 PS/286 are also compatible.

  Tech Notes:  This is a 16MHZ 80386SX-based system.  It has 1Mb of memory
  on the system board.  Intel recommends running SETBOARD for a 10MHz bus
  speed when configuring an Above Board or Matched Memory Classic.

  The system has a special slot for a Compaq proprietary memory board.  If
  this board is installed, it must be fully populated before any other
  memory board can supply EXTENDED memory.  If the Compaq memory board is
  not installed and extended memory is desired, set the Above Board or
  Matched Memory Classic extended memory start address to 1024K, (1Mb).  The
  384K of motherboard extended memory re-maps itself to where the Above
  Board or Matched Memory classic extended memory ends.

  If you should ever need to know the motherboard switch settings:  remove
  the cover and there's a diagram on the side of the chassis.

COMPAQ 386/N (386SX MACHINE)

  Compatible with current Above Boards and Matched Memory Classic.

  Tech notes:  This is an 80386SX-based system with 640K conventional, 384K
  expanded built in.  To provide extended memory using an Above Board or
  Matched Memory Classic, choose an extended memory starting address of
  1024K in SETBOARD.  Be sure Compaq's CEMM memory manager is not loading if
  using an Above Board or Matched Memory Classic as expanded memory.

  System specs:  System has two full-length 16-bit expansion slots and one
  dedicated Compaq proprietary memory slot.  VGA is built in.  Two SIMM
  sockets on system board that can take 1, 2, or 4Mb SIMMs.

  Compatible with 387SX-16 or 387SX-20 match coprocessors.  Dip switch
  setting required.  Switch block should be clearly marked and accessible.

COMPUADD 386-25

  *CUSTOMER REPORT* of compatibility with Above Boards and Matched Memory
  Classic.

  If an Above Board or Matched Memory Classic is being used to provide
  exPANded memory in this system, the Compuadd VGA ROM caching feature must
  be turned off or the EMM.SYS driver will report "All memory is either
  conventional or extended, cannot find any expanded memory to manage."

DELL 310

  *CUSTOMER REPORTS* that this 80386-based system is compatible with current
  Above Boards and Matched Memory Classic.

  Tech Notes:  Shadow RAM may cause problems with expanded memory.  Shadow
  RAM can be eliminated by disabling 'Fast ROM' and 'Fast Video' in the Dell
  SETUP program.  Keyboard controllers with versions lower than #20575 may
  also cause EMM problems.  Call Dell Tech support for a replacement.

  There is also an error in some revisions of the Dell 310 manual. The Dell
  manual states that the extended memory start address for an add-in memory
  board (like an Above Board) IF the Dell 310 is fully populated to 8M-
  bytes, is 8576.  In all actuality, the starting address if there is
  already 8M-bytes on the Dell motherboard is 8192 (there is 384K-bytes of
  cache on the motherboard).

DELL 325D (386/25)

  *CUSTOMER REPORT* of INCOMPATIBILITY with Above Boards and Matched Memory
  Classic.  Apparently all extended memory must be provided by the
  motherboard.  There is room on the motherboard to provide 16 Megabytes of
  memory, (using 1Mb SIMMs), and any additional memory would need to be
  provided through their proprietary 32-bit daughterboard.

EPSON 386/20

  Compatible with current Above Boards and Matched Memory Classic.  Must run
  MANUAL SETUP in SETBOARD and specify a 10MHz bus or the system will not
  recognize any Above Board or Matched Memory Classic memory.

  Tech notes:  This system comes with 1Mb on a proprietary 32-bit board with
  SIMM sockets to expand up to 4Mb using 256K SIMMs, or 16Mb using 1Mb
  SIMMs.  Of the initial 1Mb, 640K is conventional and 384K is reserved for
  system use so an Above Board or Matched Memory Classic can start supplying
  EXTENDED memory at the 1.0Mb address, (1024K).

  Behind a door on the front panel is a switch that sets the computers speed
  at either 8MHz or 20MHz.  There's also a reset button, speaker volume
  control & video select switch there.  Like an AT, it also has a keyboard
  security lock (make sure it's unlocked or no input gets through from the
  keyboard!).

  The system seems to have a keyboard problem similar to the Wyse,
  (keystrokes come out "shifted" to uppercase even though you don't hold
  down the shift key), though not as bad.

EVEREX
EVEREX 386-20  2800 SERIES

  *CUSTOMER REPORTS* of compatibility with current Above Boards and Matched
  Memory Classic.  Also have reports that the discontinued Above Board 286
  and PS/286 are also compatible.

  This is an 80386-based system with a BUS SPEED of 8MHz.

EVEREX SYSTEM 3000 MODEL A (386-16)

  *CUSTOMER REPORTS* of compatibility with current Above Boards and Matched
  Memory Classic.

  Tech Notes:  System bus speed is 8MHz.  To prevent floppy/tape-backup
  problems on some machines, the customer MUST obtain a PAL CHIP UPGRADE KIT
  (ask for part# ICP-00102-03) from Everex's Customer Service Department.
  (This chip would replace U69 on their mother board and is currently
  available at no charge.)

EVEREX 3000C

  *CUSTOMER REPORTS* of compatibility with Above Boards and Matched Memory
  Classic.  The Everex 3000C is a 16MHz 80386SX-based computer.

EVEREX 3000D

  *CUSTOMER REPORTS* of compatibility with current Above Boards and Matched
  Memory Classic.  The Everex 3000D is a 20MHz 80386-20 based computer.

EVEREX 3000I

  *CUSTOMER REPORTS* of compatibility with current Above Boards and Matched
  Memory Classic.  The Everex 3000I is a 25MHz 80386-25 based computer.

FALCON (FTC) 386

  *CUSTOMER REPORT* of INCOMPATIBILITY with Above Boards and Matched Memory
  Classic.  Apparently this system has a 0 wait state bus with no way to set
  it to 1 wait state.  A system running at 0 wait states violates the IBM
  specification of 1 wait state and is not fully IBM compatible.  Intel
  Above Boards require the IBM standard of 1 wait state.

GATEWAY 386 WITH MICRONICS 386 CACHE 5.0 MOTHERBOARD

  *CUSTOMER REPORTS* of INCOMPATIBILITY with Above Boards and Matched Memory
  Classic in Gateway 386 computers built around the Micronics CACHE 5.0
  motherboards.

  This is a Zero Wait state motherboard with no way to conform with the IBM
  Standard of One Wait State in the Data Bus. According to Micronics
  Technical Support the only way to add extended memory to this computer is
  on a proprietary Micronics/Gateway daughterboard.

H/P VECTRA 486

  *COSTOMER REPORTS* of compatibility with current Above Boards and Matched
  Memory Classic as extended memory.  This system has a shadow RAM which has
  been reported to conflict with an exPANded memory page frame.  It is
  unknown whether the shadow RAM can be disabled or not.

  Tech Notes:  This system has an 8MHz data bus and has a memory board
  capable of holding up to 64Mb.

HYUNDAI 386T

  *CUSTOMER REPORT* of INCOMPATIBILITY with Above Boards and Matched Memory
  Classic.  This computer runs its bus at a non-IBM-compatible 0 wait
  states, with no way to set it to the IBM-compatible 1 wait state.  A
  system running at 0 wait states violates the IBM specification of 1 wait
  state and is not fully IBM compatible.  Intel classic bus memory boards
  require the IBM standard of 1 wait state.

INTEL
INTEL 301 {INTEL 386 MOTHERBOARD}

  Compatible with current Above Boards and Matched Memory Classic boards,
  also with the discontinued Above Board 286, PS/286, AT, and PS/AT.  This
  computer operates an 8MHz bus speed.

  Factory setting has motherboard jumpers set for the 2Meg extended memory
  board that OMS (in Hillsboro) makes. It's a 32-bit board.

  To use an Above Board or Matched Memory Classic with the Intel 301 2MB 32-
  bit board as extended memory, set the Intel 301 system board jumpers as
  follows:  E29-E30, E32-E34, E35-E36.

  To use Above Boards or Matched Memory Classics as extended memory WITHOUT
  other boards in the system set jumpers on system board to connect pins E35
  & 36; E34 & 32; E28 & 30.  This sets motherboard for 512K and no 32-bit
  boards.  Install AB in 16-bit slot.

  Backfilling conventional memory from 512 to 640 will degrade system
  performance significantly.  Expanded and extended memory work fine.

INTEL 302 {INTEL 386 MOTHERBOARD}

  Compatible with current Above Boards and Matched Memory Classic boards,
  also compatible with the discontinued Above Board 286, PS/286, AT, &
  PS/AT.
