                          INSTALLING AEMM.SYS
==========================================================================

First, follow the instructions for installing your AT&T enhanced
memory expansion board.  Next, copy the file AEMM.SYS from
the Utilities 1 Disk to your fixed disk.  Then add the following
command line to your CONFIG.SYS file:

device=[drive:][path]AEMM.SYS [/X=mmmm-nnnn]

The /X parameter allows you to exclude certain address ranges of 
your expanded memory from being used for mapping.  To exclude a range
of memory, you should replace mmmm with the hexadecimal segment
number representing the beginning address, and nnnn with the
hexadecimal segment number representing the ending address of the
memory you wish to exclude.

With either a full version of Windows or with the run-time version 
included with Microsoft Excel, you should exclude that part of memory 
required by your graphics adapter.

Following is a list of the appropriate beginning and ending
segment numbers for those AT&T display adapters included in the
Microsoft Excel package.  If Microsoft Excel does not include a 
driver for your display adapter, then consult your display's 
documentation or manufacturer to determine what range of memory 
the display adapter uses.

device=[drive:][path]AEMM.SYS [/X=mmmm-nnnn]

For the AT&T DEB color display, use /X=A000-BFFF.
For the AT&T monochrome display, use /X=B800-BFFF.
For the AT&T VDC 750 (640x400) color display, use /X=A000-BFFF.
For all other AT&T color display adapters use A000-BFFF.
