6. JP9 & JP10 Setting CPU EV6 Bus Frequency
8. Connecting IDE and Floppy Cables
9. Connecting Front Panel Cable
This motherboard comes with the AMD-761 system controller that supports 200/266MHz
EV6 bus speed. Please set the proper CPU EV6 bus frequency by JP9 and JP10.
The DDR SDRAM interface allows zero wait state bursting between the DRAM and the
data buffers at 100 or 133MHz. The two 184-pin sockets, four banks of DDR DRAM can
be composed of an arbitrary mixture of 64M/128M/256M/512M/1GB DRAMs and
maximum up to 2GB.
Connect 34-pin floppy cable and 40-pin IDE cable to floppy connector FDC and IDE
connector. Be careful of the pin1 orientation. Wrong orientation may cause system
damage.
Warning:
The wrong jumper
setting may cause the CPU or
system has unexpected damage.

item in BIOS Setup, the ACPI & Power LED will keep
flashing while the system is in suspend mode.
Locate the power switch cable from your ATX housing. It is
2-pin female connector from the housing front panel. Plug
this connector to the soft-power switch connector marked
