[comp.sys.ibm.pc] bypassing power on memory diagnostics

jdmce@ecsvax.UUCP (Duncan McEwen) (10/20/87)

In PC magazine, April, 1984, a computer wizard by the name of
David McManigal published a brief article documenting a method
for inserting a 55 byte memory checking program in the boot 
record of DOS 1,2 and 2.1.  This little program allows users
with archaic 8088 machines to have the full complement of 640 k. in
memory but set the system memory switches to 64k. thus bypassing the 
lengthy power-on memory diagnostics.

I've enjoyed the method under DOS 2.1, but since upgrading my DOS, I
haven't had any success playing with 3.2's boot record. 

Is there anyone out there who can help me?

For those interested in the technique with DOS 2.1, please refer to
McManigal's article.  I have never had any program incompatibilities
using his method of four years of computing.
