Upgrade? And if so, what?

I noticed that the bios on my board allows you to increase the FSB speed
in 1 Mhz increments. I was sort of scared to try it, but basically
there's a menu item for +1Mhz or -1Mhz, and you apply it repeatedly. I
suppose one can't assume that this would actually work, but it's
interesting that the bios software allows it.

Yes, and newer boards lock the other buses down so that changing the FSB
doesn't get them out of spec. However older boards like yours didn't do
that so when you change the FSB, you also effect the other buses in the
system. Some boards allow setting the dividers of the bus speeds up to a
max the chipset supported. The divider for the via 266 chipset is 4:2:1,
at a 133MHz FSB. Meaning the FSB is divided by 4 for the nominal PCI bus
speed of 33MHz. The 2 representes a multipler of the PCI bus spee for the
nominal AGP bus speed of 66MHz and the 1 is for the ram bus speed. Divide
or multiply the FSB. Either way, it runs at the same speeds as the FSB.
Messing with the FSB speed gets tricky without a system lock on the other
buses, but it's possible to to raise it some on any system if it's allowed
in the bios.
