Warning: Intel
®
845E chipset supports maximum
400MHz (100MHz*4) / 533MHz (133MHz*4) system
bus and 66MHz AGP clock; higher clock setting may
cause serious system damage.
Note: Since the latest processor,
Northwood, would detect the clock ratio
automatically, you may not be able to
adjust the clock ratio in BIOS manually.
