Just to clarify, and for a second opinion:

The processor you have is most likely a 400mhz FSB chip. This is NOT upgradable, unless you buy a new processor, or overclock the processors FSB frequency speed. To overclock it, you would do this with the motherboards BIOS.

In order to get a better FSB, you would need a motherboard that supports at least 400mhz FSB. Most boards now will come with at least 533FSB, as that is the most popular among high-performance machines (800mhz FSB is still generally new.)

quad-rate means its 4X the Bus speed, so 100mhz X 4 = 400mhz, so your mobo is a 400mhz FSB board. Upgrading your board to 533 would not make a difference, since the chip is still 400mhz. if it IS 533, it would. The way to tell is to take the chip out and remove the heatsink, and look on the steel heat spreader, the metal peice the heatsink lays on that is attached to the processor. If it is not 533mhz FSB, then don't worry about upgrading unless you have the cash to spend on the processor.
