 LOTUS 123 & SYMPHONY KEYBOARD ERRORS

     Earlier versions of the Above Board QUIKBUF program (versions earlier
     than 2.1A), may cause random keyboard errors (such as characters
     appearing in empty cells or shifting to capital letters) in 1-2-3 and
     Symphony.  If this happens, remove QUIKBUF from the AUTOEXEC.BAT file.
     Then contact Intel's customer support BBS to get the current version of
     QUIKBUF.

 TROUBLESHOOTING - MEMORY CONFLICTS

     The following two step process has cleared up most of the EMM
     compatibility problems Intel has run across:

     1.  Add the EXPF=D000 parameter to the EMM line in the CONFIG.SYS file
         to       force EMM to use only the D000 64K-byte block of memory.

     2.  Examine your "view configuration" command for anything using
         addresses in the D000 area.  If something is using these addresses,
         move it down into the C000 area.

 DETECTING/LOCATING A BAD SIMM

     If you receive a 164 memory size error or a 201 memory type error,
     either the Above Board contains a bad SIMM or the Above Board itself is
     bad.  There are three ways to determine whether the board or a SIMM is
     causing the problem:

     1.  MCATEST will test the SIMMs on all Intel Micro Channel boards;
         Above Board MC, Above Board 2 Plus, Above Board MC32, and Above
         Board 2.  To check without MCATEST, see the two suggestions below
         for only the Above Board 2 and 2 Plus.

     2.  The 164 or 201 error message lists the failing address as well as
         the pattern of failing data bits.  If you reverse the affected SIMM
         pair and reboot the computer, you can compare the new pattern with
         the previous one.  If the pattern moved with SIMMs, the SIMM is
         probably bad.  If the pattern didn't move, the Above Board is
         probably bad.

     3.  After receiving the 164 error, press the F1 key to allow  EMM to
         install.  If EMM detects a bad SIMM, it will display a message
         indicating Memory module number x on the board in slot x is
         missing, misinstalled, or defective.  If you reverse the affected
         SIMM pair and repeat this process, you can see whether the
         defective module number moved (indicating a bad SIMM) or stayed the
         same (indicating a bad board).

     If one of the Above Board's original SIMMs goes bad, Intel will replace
     it.  If a SIMM that Intel didn't supply goes bad, you should return it
     to the place of purchase.

 RD PARAMETER DOESN'T WORK

     If you use the EXPF=D000 parameter, you can't use the RD (relocate
     driver) parameter.  When EMM loads, it will return a message indicating
     that EMM can't relocate the driver.  The computer will lose 16K bytes
     of expanded memory and won't gain any conventional memory.

 QUIKBUF PROBLEMS

 QUIKBUF POP UP MENU & ABOVE BOARD 2

     If you want to disable QUIKBUF's pop-up menu, remove the V from the
     QUIKBUF command in the AUTOEXEC.BAT file and replace it with O (for
     other).  SOFTSET doesn't support this feature.

 MORE THAN 16MB OF MEMORY IN AN 80386DX-BASED PS/2 COMPUTER

     CAUTION!  Some programs will not work correctly with more than 16MB of
     memory in the computer.  If you have more than 16MB in your computer,
     follow these guidelines:

        DISK CACHES: Don't use disk caches.  Not only will your data get
         corrupted, your hard disk format can get destroyed as well.

        RAM DISKS: Don't make one larger than 15MB or your data  can get
         corrupted.  DOS VDISK is one that will not work.

        OTHER PROGRAMS:  Ask the manufacturer if the program will run
         correctly in a computer with more than 16MB of RAM.  Some programs
         may corrupt their own data files if used with memory above 16MB.

     NOTE:   The latest MC32 option diskette must be used when installing
             two MC32's with 8MB each in the same system.   This diskette
             has the software part number 302477-001A.  The memory on boards
             installed using this diskette will be counted along with the
             system memory during boot up.

 PACKED FILE IS CORRUPT MESSAGE

     This message can be displayed when you install two of the discontinued
     Above Board 2's in the same computer at the same time.  To avoid this
     message, install one Above Board 2 at a time, allowing each to set up
     their memory without conflicting with the other.

 PARITY ERRORS - CHECK EXTENDED MEMORY START ADDRESS

     If the extended memory start address isn't correctly specified
     in the EMM.SYS command, a parity error can result.  EMM 4.0
     revision C requires the EXTF=xxxx parameter to specify the Above
     Board extended memory start address.  Earlier versions of EMM do not
     require this parameter.  SoftSet will determine this address for you,
     but here's how to determine that address yourself:

         POST + 384 = xxxx Extended memory start address

     Some computers (such as the Model 70 and 55sx) use 128K bytes
     for caching, so the count is only 896K bytes on a 1M-byte system
     board.  Here are some examples:

        1M-byte system board, no caching:  1024 +  384 = 1408
        1M-byte system board, 128K bytes cached:  896 +  384 = 1280
        2M-byte system board, no caching:  2048 +  384 = 2432
        1M-byte system board, 2M bytes on Above Board installed earlier:
         1024 + 2048 + 384 = 3456

     The Model 55SX and 70 computers map the EPROMs into RAM, so there is
     128K bytes less extended memory available.  Choosing the 70 setting in
     older versions of SoftSet that don't have a model 55SX option will
     provide the correct extended memory start address in a model 55SX.
     Choosing 50 will create a 128K-byte gap, and accessing memory will
     cause a parity error.

     An older version of SoftSet (ver 1.2) had a bug; every time it's run it
     will add the amount of memory on the Above Board to the existing
     starting address and make a higher start address. Manually edit the
     line to show the correct address.

 SYS 1198 ERROR MESSAGE

     This error can occur when the ILIM386.SYS command is in the CONFIG.SYS
     file for OS\2.  You must remove the iLIM386.SYS command.  Both OS\2 and
     ILIM386 are memory managers, and they can't co-exist in the same
     computer.

 ZERO WAIT STATES WITH ABOVE BOARD 2 AND 2 PLUS

     To run the Above Board 2 or Above Board 2 Plus at 0 wait states in an
     IBM model 50 or 60, you must use 100ns SIMMS, run SOFTSET and specify
     the "disable" or "mappable conventional" feature.  This disables the
     system board memory which is slower than 150ns memory.

     The IBM model 50z is designed to run only with 0 wait states and will
     not benefit from this procedure.

 MISSING OR WRONG DISK AND MANUALS

     If you receive the wrong diskettes or manual with your Above Board, do
     the following:

     1.  Note whether the Above Board box was unopened before you bought it.

     2.  Gather the following information:
         a.  Serial number of the Above Board
         b.  Date on outer label of Above Board box
         c.  Name and address of the dealer who sold the Above Board
         d.  List of missing items

     3.   Call Intel Customer Support
