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 produce this power on failure.
1. Check ROBO-698 jumper JP3. For ATX power supply or AT power supply
used for AT system, JP3 needs to be at 1-2. Otherwise, it needs to be at 2-3.
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 JP2
(CMOS clear Jumper), power on the system to clear CMOS, power off the
system, remove JP2 jumper, and power on again.
Q: 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-698 does not have switch or jumper to configure
CPU core/bus ratio. This is done through BIOS setting. Please check in the
“CPU Speed Setting” section of Chapter 4 (4-12) to adjust this core/bus ratio.
System default setting is “x5.5”, and hence you should always get a speed of 366
(66MHz FSB), or 550 (100MHz FSB) at boot up after load in the BIOS optimal
default.
Q : I connect two IDE devices over one IDE flat cable, but the system either
does not start or hangs from time to time. Why ??
A : Make sure that you have configured the two IDE devices as master and slave,
respectively.
