FSB Speed Auto Configure Setting (J1, JP5, JP3)
ME21 provides jumper J1, JP5 and JP3 to set auto configure front side bus at
66MHz, 100MHz, 133MHz. Insert mini-mini jumpers on JP5 and JP3 and
leave J1 all open as below to identify automatically the FSB speed.
Default
When the FSB auto config. function is enabled, the user may still adjust CPU
Host clock through the option "CPU HOST/PCI Clock/PC133" in seb-menu
of "Frequency/Voltage Control" of BIOS setup program.
For experienced users, ME21 mainboard provides an alternative hardware
configured function to adjust Front Side Bus manually. Before you adjust FSB
frequency by jumper, you need to remove all mini jumpers from JP5, JP3 and
insert mini jumpers properly on J1 and set "CPU HOST/PCI Clock/PC133"
option in seb-menu of "Frequency/Voltage Control" of BIOS setup program.
