Front Side Bus (FSB) Speed Auto Config. Setting
(JP16 and JP14)
AV14 provides jumper JP14 and JP16 to set auto configure front side bus at
66MHz, 100MHz and 133MHz. Inserting mini-jumper caps on JP16 and
leave JP14 all open as below to identify automatically the FSB speed.
When the FSB auto config. function is enabled, the user may still adjust CPU
Host clock on each FSB from Chipset Feature Control of BIOS Setup pro-
gram.
For experienced users, AV14 mainboard provides an alternative hardware
configure function to adjust Front Side Bus (FSB) manually. Before you adjust
FSB frequency by jumper, you need to remove all jumper caps from JP16
and insert jumper caps properly on JP14 and set CPU Host/PCI Clock to
default
in Chipset Features Control of BIOS setup program.
