ROBO-8712E Series User’s Manual
5-8
For example, when using the DDR333MHz SDRAM Memory with FSB400MHz
CPU, the board will down grade the memory clock frequency to DDR200MHz.
Q: In addition to the above description, is there anything to do to finish up an
ATX system?
A:
Yes. ROBO-8712E needs to be configured to support ATX function for the above
cabling. Please move jumper JP3 to 3-5 short and 4-6 short (support ATX
function).
Q: How can I build up an AT system using ATX power supply
A:
Do not forget to move JP3 of ROBO-8712E back to 1-3 short and 2-4 short (support
AT function).
If the ATX power supply has a switch, such as ORION-330ATX-12V, do not
remove the jumper of Backplane connector in step 1, and use the power supply
switch as the system power on switch.
In all cases, users may apply a 2-pin AT (on/off) switch over pin-3 and pin-4 of
the Backplane connector in step 1. However, power supply switch needs to be
moved to “on”, if there is one.
Q: How to use Standard PS/2 Keyboard and Mouse?
A:
Users may always adopt the USB Keyboard/Mouse though the USB ports on the
back bracket.
Also, Users may adopt PS/2 keyboard and mouse over the J4 connector interface
on ROBO-8712E. The PS/2 extension cable is the optional device for the ROBO-
8712E, which is only made for ROBO-8712EVG2A.
