INSTALL THE INBOARD 386/PC (MOST SYSTEMS)

  Installing the Inboard 386/PC is a two-step process:

  1.   Putting the board into the computer

  2.   Copying and configuring the Inboard 386/PC software

  INSTALLING THE BOARD

  Before installing the Inboard 386/PC, verify that your computer is
  operating correctly.  Fix any existing problems before adding the
  Inboard 386/PC.  Once you know the computer is operating correctly,
  follow these steps to install the Inboard 386/PC.

  1.   Turn off the power switch on the computer and any attached
       equipment, and unplug the computer's power cord from the outlet.

  2.   Remove the computer's cover.

  3.   Remove any boards installed between the 8088 socket and the slot
       in which you're going to install the Inboard 386/PC.

  4.   Set the computer's system board switches to specify the
       appropriate amount of conventional memory.

  5.   Disable any conventional memory provided by add-in boards or
       remove the boards.

  6.   Remove the 8088 microprocessor.

  7.   If an 8087 is installed, remove it.

  8.   Align the Inboard 386/PC cable connector with pins over the 8088
       socket (not the 8087 socket) so that pin 1 on the cable is at the
       notched end of the socket.  Check for proper pin alignment before
       applying pressure.

  9.   Install the Inboard 386/PC into a full-length slot that is within
       reach of the cable.

  10.  Replace any boards you removed from the computer.

  11.  Route the Inboard 386/PC cable over (or, in some cases, under)
       other boards to the Inboard 386/PC.

  12.  Connect the free end of the cable to the Inboard 386/PC.

  13.  Replace the computer's cover, connect any cables you disconnected,
       and plug the power cord into the outlet.

  INSTALLING THE SOFTWARE

  Installing the Inboard 386/PC software is a two-step process:  copying
  the software to the root directory and setting up the software (by
  adding commands to the CONFIG.SYS and AUTOEXEC.BAT files).

  If you can't find the Inboard 386/PC software, you can download the
  latest versions from the Intel Bulletin Board System or from Compuserve.

  COPYING THE INBOARD 386/PC SOFTWARE

  Before you can use the Inboard 386/PC software, you must copy it to your
  hard disk's root directory or your system diskette.  Copy only the
  software you need.  Here's a short description of the software:

  INBRDPC.SYS     Controls extended memory and speed control keys.

  ISTATPC.EXE     Displays the status of the INBRDPC.SYS settings.

  ICACHE.COM      Controls the Inboard 386/PC's cache.

  ILIM386.SYS     Turns extended memory into expanded memory.

  ILIM386.COM     Displays the status of all memory in the computer.

  ISPEEDPC.COM    Changes computer speed from the DOS prompt or a batch
                  file.

INBRDPC.SYS PARAMETERS

  Add the following command to the CONFIG.SYS file:
  DEVICE = INBRDPC.SYS [SPEED=n] [EGACACHE] [NOCACHE][NODIAGS] [NOPAUSE]
