Quick Review

The PS/2 keyboard communicates with the keyboard controller on the motherboard via a serial data link. The speed of the data link depends on the clock signal generated by the keyboard controller. The higher the clock speed, the faster the keyboard interface. This translates into a more responsive keyboard although not all keyboards can work with higher clock speeds.

This BIOS feature allows you to adjust the keyboard interface clock for a better response or to fix a keyboard problem. It is recommended that you select the 16MHz option for a better keyboard response. But if the keyboard performs erratically or fails to initialize, try a lower clock speed.
