Warning:
Intel 845GV chipset supports maximum
400MHz (100MHz*4) / 533MHz (133MHz*4) system bus
and 66MHz AGP clock; higher clock setting may cause
serious system damage.

Since the latest processor, Northwood,
would detect the clock ratio automatically,
you may not be able to adjust the clock ratio
in BIOS manually.
