 NEW SIMMS NOT RECOGNIZED

     For Above Board MC32 installed with ADP: If any SIMMS are bad, no
     memory will be recognized.  There won't be any error messages, the
     memory will simply not install. Run MCATEST to determine the
     misinstalled or defective SIMM.

     Tech Notes: With the ADP installation, the Above Board memory counts
     with the system memory when you power up the system.  With the iADF
     installation, the Above Board memory is reported in the Intel banner
     which displays right after the system memory count.

     For Above Board MC32 installed with iADF, follow these steps to rerun
     the Reference diskette and change the configuration whenever you add or
     remove SIMMS.

     1.  Boot to Reference Diskette.

     2.  Choose Set Configuration, Change Configuration.

     3.  Change the memory amount for the Above Board and press F10 to save.

 MEMCHECK LOCKS UP

     Customer reports indicated that this diagnostics program locked up
     after running in a 16-MHz IBM Model 80 with IBM DOS 4.01.  Customers
     with this version of Intel software should get the latest shipping
     version of the Above Board MC32 software, (which is available on the
     Intel BBS).  If you are experiencing this problem and the installation
     isn't complete and you need to get the memory installed before the new
     software arrives, you can follow these steps:

        Reboot to the hard disk (or DOS disk)
        Insert the Intel Setup diskette in drive A, and type A:SETUP.

     The Setup program will install the initializing ADF.  It's best to get
     the new software.

 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.

 USING TWO ABOVE BOARD MC32S IN ONE SYSTEM

     If you have two Above Board MC32s, each with 8M bytes, in the same
     computer, you must use the current installation software which utilizes
     an ADP (Adapter Description Program) to initilize the Above Board MC32
     instead of the old IADF (Initializing Adapter Description File).  With
     the ADP installation, the Above Board MC32 memory is counted with the
     system board memory on power up.  The older installation method where
     the memory on the Above Board MC32 was reported on an IADF banner just
     after the system board memory counted  won't allow two fully populated
     Above Board MC32s.

     NOTE           Some programs may malfunction with more than 16MB of
                    memory on a computer.

 111 ERROR ON A NEWER MOD 70

     If you experience 111 errors on boot or after loading a program that
     uses the Above Board MC32, your computer may not be compatible with the
     original MC32 board.  Check the location of the system board SIMM
     sockets.  If your system board is the newer design,  the SIMM sockets
     will be under the hard disk.

     Intel has identified and fixed the problem with a modification to the
     MC32 board.  The new Above Board MC32s have a manufacturing code which
     ends in 002 or higher.  The manufacturing code is on a small, white
     sticker to the right of the serial number.  Call Intel Customer Support
     if you have questions or need assistance.

 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.

 "DOS 123 ERROR: PROTECTED MODE REQUIRES VCPI WITHIN VIRTUAL 8086"

     This error message is produced with an Above Board MC32, ILIM386.SYS
     version 4.04, and software designed to conform to the Virtual Control
     Program Interface (VCPI) specification. ILIM386.SYS version 4.07 does
     not have this problem.

     Although ILIM386.SYS version 4.04 was designed to conform with software
     using the VCPI specification, a problem with the ILIM VCPI
     implementation causes Lotus 1-2-3 Release 3 to hang with the message:
     "DOS 123 ERROR: Protected mode requires VCPI within virtual 8086".

 "TOO MUCH EXTENDED MEMORY" ERROR

     This error occurs when Above Board MC32 ADP installation software is
     used on a system in which an MC32 was previously installed.  If the
     previous MC32 was installed using the iADF installation software but
     was never completely uninstalled, an error will be returned stating
     that there is too much extended memory.

     The solution is to completely uninstall the MC32 using the iADF
     software, then reinstall using the ADP software.

 IBM ADVANCED DIAGNOSTICS AND THE MC32

     Be careful in running the memory diagnostics from the reference
     diskette of a Model 70 or 80 when the Above Board MC32 is installed.
     The standard tests on the main menus will work fine, but the advanced
     diagnostics on a hidden menu will cause problems.  You activate these
     advanced diagnostics using the Ctrl-A command.  Do not run these memory
     tests!  We're telling you the command only so you know never to use it.

     The problem arises because these tests only see IBM memory.  Since they
     don't see the MC32 (or any other add-in board) the program remaps the
     IBM memory right on top of the MC32, thus creating a conflict.  The
     next time you reboot, you'll get a 164 error.  You may also see a
     message that says the system board is bad.

     To fix the problem, boot to the Reference diskette.  Select Set
     Configuration then Change Configuration.  Verify the Above Board MC32
     information, then hit the F10 key to save. Reboot to the hard disk and
     there should be no error messages.
