Are you sure the memtest program is compatible with the cpu and ram?

Fairly sure, but isn't that kind of irrelevant to my question? Again,
the Memtest program indicated that although there was 1.8+ GB of
unallocated RAM, XP Pro would only allocate about 1475 MB of that 1.8
GB to a single program. My question is, again, if my motherboard had
4 GB of RAM instead of 2 GB, would XP Pro permit more RAM allocation
to a single program or is this ~1475 MB a fixed limit in XP Pro?

Is it a program that runs from a floppy?

It is an exe with no support files and can be run from just about any
medium (floppy, hard drive, CD Rom, USB drive, Tape Drive...).
