Q: How can I build up an AT system using ATX power supply
A:
Do not forget to move “JP1” of ROBO-6710/6730 back to short on 1-3, 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 the Figure 5-2, 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 the Figure 5-2. However, power supply switch needs
to be moved to “on”, if there is one.
Q: OK. I have finished up hardware installation, but I got nothing when I power
on the system. Why?
A:
There are thousands of different reasons to get this power on failure.
1. Check ROBO-6710/6730 jumper, JP1. For AT power supply or ATX power
supply used for AT system, JP1 needs to be at 1-3 and 2-4. Otherwise, it needs
to be at 3-5 and 4-6 for ATX mode. Incorrect power setting will not allow you
to power on the system.
2. Double check if every connector is attached with the correct cable.
3. If you have changed processor with different system clock, please short JP7
(CMOS clear Jumper), and power on the system to clear CMOS (move on/off
switch from off to on for AT mode, or toggle the switch for ATX mode); then
power off the system, remove JP7 jumper, and power on again. This way to
process the action for “Clear the CMOS Setting”.
