This program is only useful in a single scenario.  If you have this setup:

  - 8086, 80186, or 80286 CPU
  - 640K low DOS RAM
  -  64K located at A000 (for example, provided by a Lo-Tech RAM board)

...but your BIOS won't recognize the extra 64K past the end of 640K, then this
program allows you to fix that by patching the boot sector to force the BIOS
Data Area "memory size" variable to 704K.  DOS will honor that size while
loading, giving you a total of 704KB free DOS RAM.

By making this adjustment before DOS or device drivers load, it is compatible
with anything that loads afterwards, such as EMM drivers, QRAM, etc.

The program is interactive (no command-line options).  The program also has
several safety checks to prevent mangling your boot sector, but just in case
I'm a moron, make a boot disk with SYS and FDISK on it before running this
program.  If you're nervous, you can test on a floppy disk before committing
to patching the hard drive.  But whatever happens, you use this program at
your own risk; I cannot be held responsible if you screw up your vintage PC.

Made with Turbo Pascal 7 and the A86 assembler.
