 BASIC TROUBLESHOOTING

     1.  Make sure the power cord is plugged into the wall outlet.

     2.  Make sure all boards are replaced and reseated correctly and all
         cables are attached correctly.

     3.  Reseat the Inboard cable.  Check both ends of the cable for bent
         pins and misalignment in the socket.  Make sure the cable is
         installed with pin 1 in the correct corner of the socket.

     4.  Make sure the Inboard cable hasn't been creased and uncreased.
         Uncreasing the cable can damage it.

     5.  Move the Inboard to a different slot.  The slot it's in could be
         defective.

     6.  If the computer has an LCC socket adapter, check for a bent spring
         clip in the corner of the 80286 socket.  A bent spring clip will
         short the two corner pins of the cable, and the computer won't
         boot.

         First remove the cable from the socket and check the spring clip.
         If it's bent under the corner of the cable, bend it back.  (If it
         breaks, don't panic -- the socket clip should hold the cable
         securely enough. However, you must find the piece that broke off
         and remove it.)  Next, carefully push the spring clip out of the
         way and seat the remaining corners of the cable squarely in the
         socket.

     7.  Make sure the 80287 plug is installed correctly.  Check it for bent
         pins and misalignment in the socket.  Installing it backwards can
         cause computer not to boot.

     8.  Check the switch settings, system board jumper settings, and memory
         addressing on conventional and extended memory boards in the
         computer.

     9.  If the computer displays a memory size error even when memory
         settings are correct and Setup has been run, check for bent pins on
         chips or chips installed backwards.

     10. Note any beeps the computer sounds.  Record the number and type
         (long, short, different pitch).  Different beeps indicate different
         problem:

     Ŀ
      These sounds:               Indicate a problem with this:   
     ͵
      CONTINUOUS BEEP             The power supply

      1 LONG AND 3 SHORT BEEPS    Enhanced Graphics Adapter       
     

     11. Check the FaxBack compatibility documents for specific
         compatibility information about your computer and the other
         products you use.  These documents contain specific information
         that a general troubleshooting guide can't cover.

 ADVANCED TROUBLESHOOTING

     If the computer powers up correctly, but you experience software errors
     or lock ups after installation, try the following:

     1.  Change to another speed.  Try loading programs in Speed 1 and using
         them in Speed 4.

     2.  Check switch and jumper settings that configure memory.  Look for
         two different boards set up to supply memory at the same addresses.

     3.  If the computer displays a memory size error even when memory
         settings are correct and Setup has been run, check for bent pins on
         memory chips or chips installed backwards.

     4.  Remove ILIM386 from CONFIG.SYS if it is installed.  If this
         resolves the  problem, the ILIM386.SYS program may be corrupted.
         Delete ILIM386.SYS from your hard drive and reload it from your
         original Intel diskette. The latest InBoard 386/AT software is
         available on the Intel BBS (503) 645-6275 8 data bits, no parity,
         one stop bit, up to 9600bps. If new software does solve the
         problem, it may be necessary to try another 386 specific memory
         manager (like QEMM386.SYS by Quaterdeck or 386ToTheMAX by
         Qualitas).

     5.  Be sure there are no interrupt conflicts between other hardware in
         the computer (for example, between a mouse and a network card).
         The Inboard doesn't use interrupts, but it can accentuate conflicts
         that already exist.

     6.  Remove INBRDAT.SYS from the CONFIG.SYS file. If this resolves the
         problem, the INBRDAT.SYS program may be corrupted. Delete
         INBRDAT.SYS from your hard drive and reload it from your original
         Intel diskette. The latest InBoard 386/AT software is available on
         the Intel BBS (503) 645-6275 8 data bits, no parity, one stop bit,
         up to 9600bps.

     7.  Check the Inboard cable for bent legs that are making intermittent
         contact.

     8.  Check the FaxBack compatibility documents for specific
         compatibility information about the programs with which you're
         having trouble.  These documents contain specific information that
         a general troubleshooting guide can't cover.
