This code is simple MASM code that can be used to size the DRAM of the
NS486SXF evaluation board.  This is done automatically with versions
2.4 and newer of the Flash Loader.  However, this code could serve as
an example of sizing DRAM on a proprietary board.

This code is similar to the "Boiler Plate" code in the BOILER directory.
You may wish to become familiar with that code before using this code.

This code is very specific to the evaluation board.  That is, it
will only size 1, 4, and 16MB 72 pin SIMMs connected to the ns486sxf
as on the evaluation board.  Similar techniques could be used for
other board designs, but the code will need to be modified.

The provided .FLC script will allow you to program and boot this program
from the Flash Loader.  It will size the DRAM, configure the DRAM, and
then jump to a user definable area (0xFFFCFFF0).

This is version 1.1.  The only change between this version and the original
is that this version restores the original DRAM contents to DRAM after
each check, so no DRAM locations are changed by this program.
