How do I adjust timer latency?

[scourge]

The System:
FIC VA-503+ version 1.2a (BETA BIOS JE4330)
AMD K6-3+ @ 504 (112x4.5)
128meg PC100 Kingston ValueRAM (CAS 2)
Diamond Speedstar a200 (8meg AGP savage4)
Soundblaster 16 or S3 sonicvibes
Win ME

Anyway, I've been having annoying pauses during games. I keep GLQuake around to run quick and dirty benchmarks because it loads so quickly and you can get a fps score real quick. I've been getting these intermittent pauses (at any resolution) in any 3D game I play (UT, HL, ST:Armada, Tachyon). I thought it was the sound card at first, but I swapped it out and had the same problem.

So I ran Sandra 2000 and it says that my timer latency for using the PCI/AGP bus is too high which can cause problems with sound/network cards because the video card is hogging the motherboards bandwidth. Right now it reports my timer latency is 248. It suggests a setting of 64 or 128 with the possible range being 32 to 255. The help file told me to go into the BIOS and change it. Which I tried, but I don't see that setting anywhere. I searched the registry, etc. I don't know where this value is or how to change it. Please help!!! Thanks!!!

I don't know about FIC mobos but any mobos that have the Softmenu for bios have an option for that in the same sub-menu where you change the system bus speed and such.
