 NETWORK BOARDS - GENERAL NOTES

     Network Boards - General  Notes     
     If an Above Board or a Matched Memory Classic supplies expanded memory,
     there could be a conflict with the RAM and/or ROM of a network board in
     the same system.

     Expanded memory requires that there be a contiguous 64K Expanded Memory
     Page Frame in reserved memory.  The Intel expanded memory manager
     device driver (ISAEMM.SYS or EMM.SYS) "seeks" for a contiguous 64K
     available space within the address range C000-DFFF at boot time.  Often
     the RAM or ROM of network cards is not active at boot time so the Intel
     expanded memory manager does not "see" it.  Consequently, the address
     space used by the network board is already being used by the expanded
     memory for the page frame.  Common symptoms are applications locking
     up, garbage in spreadsheet cells, or not being able to logon to the
     network.

     All current versions of the Intel expanded memory manager have
     parameters available that can exclude a certain range of address space
     from being used so that the expanded memory page frame will not
     conflict with the ROM or RAM of network boards.

 3-COM ETHERLINK

     Compatible with Above Boards. Memory address is at EC00h.  This should
     not be a problem with ABs providing expanded memory. In 8088- and 8086-
     based computers make sure EMM doesn't start at the E000h address.

     See 3Com's EtherStart User's Manual for other address settings.

 3-COM ETHERLINK II

     Compatible with Above Boards.

     Tech Notes: Etherlink II board can use addresses C8000, CC000, D8000,
     DC000 when optional EtherStart II PROM is installed on the board.

     "Disable" is an option to use when the ES II PROM is not installed.
     Addresses are set by jumpers on the board.

 ACER ARCNET

     *FIELD REPORTS* of compatibility with Above Boards.
     The ACER Arcnet 5210-003, has only two address options C000 and D000,
     this may not leave enough address space for the expanded memory manager
     to load in an 80286-based computer if there is also a EGA or VGA
     present.

 ALLEN BRADLEY VISTA LAN BOARD

     *FIELD REPORT* of compatibility with current Above Boards.  Can use
     D000 (I/O 2E0) or E000 (3E0), software INT 61 for Vines software

 AQUILA ARCNET

     *FIELD REPORTS* of compatibility with Above Boards.

     Tech Notes: Memory choices: E100, E000, DD00, DC00, D900, D800, D500,
     D400, D100, D000, CD00, CC00, C500, C400, C100, C000.  Switches on the
     memory I/O switch block (RAM & EEPROM). Apparently this board uses 8k
     of reserved memory space (the manual was unclear).

 AST PC-NET

     LIMITED COMPATIBILITY with Above Boards. This network is incompatible
     with all L/I/M EMS boards because it uses interrupt 67h, Above Boards
     set as EXTENDED memory should have no problem working with this network
     adapter.  AST has discontinued this network adapter and replaced it
     with the RSN Network.

 AST RSN NETWORK

     We have no compatibility information at all between this network
     adapter and Above Boards. We've learned that this is a replacement for
     the AST PC-NET, (which was incompatible with L/I/M EMS), but that's all
     we know at this time. We have had no customer calls with problems with
     this network adapter and Above Boards.

 AT&T STARLAN

     *FIELD REPORTS* of compatibility with Above Boards.

     Tech Notes: Has 7 different memory address locations which can be
     selected by jumpering the appropriate pins in the RAM MEMORY jumper
     block.  Setting choices are 8, 9, A, B, C, D, E.  This corresponds to
     memory addresses at 80000, 90000, A0000, B0000, C0000, D0000, E0000.
     Novell recommends address C0000.  If the C0000 block does not work, try
     experimenting with other memory addresses.  (The Starlan manual does
     not suggest using any addresses other than C0000.)

 BANYON

     Banyon has reported compatibility with ABs

     Banyon SW has a PCCONFIG file that has a menu to set Interrupt level,
     check hex address space, etc. for several different boards including
     two selections for the Token Ring board: "Token Ring" &  "Token Ring
     with LAN support (TOKREUI)".  The "Token Ring" option DOES NOT require
     the Token ring drivers in either the CONFIG or AUTOEXEC files.
     Changing the RAM address in PCCONFIG is sufficient to eliminate the
     EMM/Network conflict.

     If the user has the Token Ring drivers in either the CONFIG or AUTOEXEC
     files, they need to choose "Token Ring with LAN Support" option, change
     the shared RAM address AND append the new address onto the end of the
     Token Ring command line (ie. "DXMC0MOD.SYS ,C800" or "TOKREUI ,C800").

 CORVUS

     Compatible with AB per field reports.

     Two customers report that TESTAB will not run correctly when a Corvus
     board is installed (TESTAB returns patterns of bad chips). By pulling
     the Corvus card they were able to get accurate results with TESTAB, (at
     which point they reinstalled the Corvus card). This would seem to be a
     conflict between the TESTAB program and the Corvus card, NOT between
     the Above Board and the Corvus card.

     Field report that Corvus uses D0000 ROM address, but we don't know if
     that's movable or if it uses the entire D0000 range.

 CORVUS OMNINET

     *FIELD REPORTS* of compatibility with Above Boards.

     Tech Note:The address of the Remote Reset PROM is not given in the
     Novell manual.  If conflicts occur with EMM when the Remote Reset PROM
     is installed, have user check his Corvus documentation for the PROM
     address.

 DATA AQUISITION CONTROL

     *Customer Reports* of LIMITED compatibility with Above Boards. There
     are no reported problems if the Above Board is providing Extended
     memory, however in 80286-based computers there won't be enough reserved
     memory address space to provide expanded memory.

     This proprietary Network Board resides at D000-DFFF, system will also
     have Hi-Res PGA Board at C600 and uses 1K.   Neither are switchable.

 DEC ETHERNET BOARD

     Field reports of compatibility with Above Boards.
     Tech Note: The DEC Ethernet board uses 64K of memory addresses starting
     at either D000 or E0000.

 DEC PATHWORKS ETHERWORKS BOARD

     *CUSTOMER REPORT* of compatibility with Above Boards.

     Tech Notes:  The DEC Pathworks Etherworks board defaults to using 64K
     of reserved memory at D000.  It can be set to a size of 32K and
     alternate reserved memory addresses available are C800-CFFF, D000-D7FF,
     and E000-E7FF.

 DECNET

     *FIELD REPORTS* of compatibility with Above Boards.

     This board is now shipped with new software and new jumper settings
     available from DEC. The board can now be used with the following
     reserved memory page frames:

                Primary mode - 64K page frame   D0000-EFFFF
              Secondary mode - 64K page frame   E0000-FFFFF

                Primary mode - 32K page frame   D8000-DFFFF
              Secondary mode - 32K page frame   C8000-CFFFF
     -Old boards used primary address: D0000-DFFFF.  AB would not find
     enough reserved memory address space to install expanded memory with
     both the older Decnet and an EGA or VGA in the system.

 DEC DEPCA CARD

     *FIELD REPORTS* for revision "E" Depca card and Above Boards.

     This board has 64K & 32K mode.  Jumpers W7 & W8 control memory size and
     address.  When the board is set to 32K mode, 32K of conventional memory
     are locked out for the board's use.

     For the revision "E" board, jumper settings are:

     W7   W8    Size  Address
     ---  ---   ----  -------
     ON   ON    64K   D000
     OFF  ON    64K   E000
     ON   OFF   32K   D800
     OFF  OFF   32K   C800

     * Note: The jumper functions vary with the board revision & network
     software version. Refer to DEC documentation.

 DEC DEPCA LC BOARD

     This board can use a 32k or 64k block of reserved memory. It is
     configurable by its switch block that has 12 switches.

     The reserved memory location can be set by the following switch
     combinations:

     SW1    SW2     SW3     SW4      ADDRESS        BUFFER SIZE
     Off    On      On     On     C0000-CFFFFh        64kb
