Onboard hardware installation
Q1: How do I connect my PS2 keyboard and mouse?
A:
PS2 Keyboard and mouse cable is an option kit of ROBO-8911. If you have PS2 kit
please connects it to J33 of ROBO-8911.
Q2: 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-8911 jumper, JP9. For AT power supply or ATX power supply used
for AT system, JP9 needs to be opened. 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. Please move JP6 (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 JP6 back to 1-2, and power on again.
Q3: I power on the system, but the CPU speed is not correct. Why?
A: This applies to Engineering Sample processor ONLY.
If you have ever loaded
the BIOS optimal default, thank you for doing so. However, this will force the
BIOS to pick up the default CPU core/bus ratio as well. It needs to be emphasized
again that ROBO-8911 does not have switch or jumper to configure CPU core/bus
ratio. This is done through BIOS automatically. Please check in the
“Frequency/Voltage Control” section of Chapter 4 (4-11) to adjust this core/bus
ratio (only available when you plug in the engineering sample processor from
Intel). System default setting is automatically setting when you plug in
commercial processors from Intel and you will not see the CPU Clock Ratio item in
the BIOS setting screen.
