I believe most AMI BIOS' allow you to change the division factor (CLKIN/6,5,4)
in order to change the bus speed.  Be careful when you do this however!!  Some
other boards cannot keep up with faster bus speeds.  For example, when my
brother changed the bus speed on his 486/50 from 8.33MHz to 12.5 MHz, he got
strange errors sporadically.  The only one he could replicate was during
installation of Ultima Underworld, and the error had something to do with
writing to the hard drive.  After Norton Disk Doctor could'nt help him we
finally realized that the error cam from a mismatched bus speed with the 
hard drive controller card.  Once the bus speed was changed back to 8.33 MHz,
there were no more problems.  Hence, the moral of the story is, you can try
to increase your bus speed, but if your cards can't keep up, and you get 
strange behavior from your computer, go back to the trusted old 8 MHz.
