Warning: Intel
®
845G chipset
supports maximum 400/533MHz
(100/133MHz*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.
