- 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.
