This program will enable you to change the Front Side Bus on your Abit BP6 dual Celeron motherboard; it works in Windows98, WindowsME, WindowsNT, Windows2000, and WindowsXP.
Warning: Overclocking puts more stress on hardware and can lead to hardware failure. If you are new to overclocking browse the message board for more information before attempting to squeeze any more juice out of your computer.
Because this program is so old, support is very limited. If you have read through the "help" in the program and still cannot find an answer to your question the best thing to do is read through the message board.
If you have some time, and are experienced enough, you may want to take a look at the source code too!
