Hardware Installation
Q: How do I connect my keyboard and mouse?
A
: Users can always adopt the PS/2 keyboard and mouse over the PS/2 interface
(through Ycable), J18. However, it is also OK to adopt a standard keyboard over the
standard keyboard connector on the backplane, if provided. Users need to adopt a 5-pin
keyboard connection cable to line up the keyboard interface, J22, with the 5-pin
keyboard connector on the backplane.
Q: OK. I have finished up hardware installation, but nothing happens when I
power on the system. Why?
A
: Try the following solutions.
1. Check 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 settings will not allow you to power on the system.
2. Double check whether every connector is attached with the correct cable.
3. If you have changed processor with different system clock, please move JP2
(CMOS clear Jumper) to 2-3, power on the system to clear CMOS, power off the
system, move JP2 back to 1-2, 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 this
SBC does not have switch or jumper to configure CPU core/bus ratio. This is done
through your BIOS setting. Please check in the "Frequency/Voltage Control" section of
the BIOS chapter to adjust this core/bus ratio.
Q: I connect two IDE devices over one IDE flat cable, but the system either does
not start or hangs. Why?
A
: Make sure that you have configured the two IDE devices as master and slave,
respectively.
Q: I am using an ATA-66 hard drive, how can I know that ATA-66 function is
started?
A
: You need to use the 80-pin ATA-66 IDE flat cable to have this function ready. During
POST, you can see ATA-66 message while the hard drive is being detected.
