underclocking or CPU frequency scaling

I have an older desktop:

motherboard:  SiS-661GX
CPU:          Intel(R) Pentium(R) 4 CPU 2.53GHz

and would like to set a "max" for CPU usage to prevent overheating.  
Generally, it's fine, but for some processes I want to set a sort of 
"nice" so that the CPU doesn't get pegged.  Longer compiles would be fine.

Frequency scaling and underclocking can only be done through supported 
hardware, generally the BIOS?
