Q: How can I build up an AT system using ATX power supply
A:
Do not forget to move JP3 of ROBO-8712VLA back to 1-3 short and 2-4 short
(support AT function).
If the ATX power supply has a switch, such as ORION-300ATX, 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 do I connect my keyboard and mouse ?
A:
Users may always adopt PS/2 keyboard and mouse over the PS/2 interface
(through Y-cable), J13 on ROBO-8712VLA.
However, it is also fine to adopt a standard keyboard over the standard
keyboard connector on backplane, if provided. In this way, users need to adopt a
5-pin keyboard connection cable to line-up, external keyboard interface, J14 on
ROBO-8712VLA with the 5-pin keyboard connector on backplane.
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-8712VLA jumper, JP3. For AT power supply or ATX power
supply used for AT system, JP3 needs to be at 1-3 and 2-4. Otherwise, it needs
to be at 3-5 and 4-6. 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 move JP1
(CMOS clear Jumper) to 2-3, 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), power off the system, move JP1 back to 1-2, and power on again.
