Your post makes no sense whatsoever.

1) WTF does "I replaced the original pentium" [/sic/] mean? You have
*NEVER* had a Pentium chip - Pentium is a trademark applied to certain
*Intel* CPUs, you've never had an *Intel* CPU in that box, you've had AMD
CPUs. A Pentium CPU will *NOT* fit in a board designed to accept an Athlon
CPU.

2) Nor has this anything to do with Windows, it is a BIOS issue and the
BIOS has nothing whatsoever to do with the operating system. The simple
answer is you have the FSB set incorrectly.

3) It really irks me when people refer to the BIOS as "the CMOS" - the
two terms are mutually exclusive and *NOT* interchangeable. It just shows
your ignorance: -

CMOS: - Complementary Metal Oxide Semiconductor, and is the name appiled to
the chip where the BIOS information is stored.

BIOS: - Basic Input Output System - this is where the basic information
about your computer is, when you save, it is *written* to the CMOS.
However, you do *NOT* "enter the CMOS".

4) Suggest that you need to change the multiplier. AthlonXP chips are
locked at a multiplier of 15, therefore you need to make sure the FSB is set
to 133 (133 x 15 = 2000 give or take (it's actually 1995, but the FSB has to
be a whole number; you cannot set it to 133.33 recurring)).
