Unboot problem
Symptom: After changing power mode from ATX to AT, my system is just not
working.
Solution:
Due to ICH5 design, when you change your power mode from ATX to AT
or from AT to ATX, you have to clean your CMOS in order to make your
system boot up properly. To clean CMOS, please short 2-3 pins on JP2 for
a moment, and then change it back to its default setting.
Symptom: SBC keeps beeping, and no screen has shown.
Solution:
In fact, each beep sound represents different definition of error message.

Symptom: There is neither no beeps nor screen output.
Solution:
Indeed, you can do the stand-alone to identify the root cause by isolating
the board from other possible system devices such as PCI device,
backplane, and so on. If the system still cannot boot up, please fill out
RMA from which is provides on Portwell website, and then send back to
Portwell as a RMA. Besides, you also visit RMA site
(http://www.portwell.com.tw/rma/login.asp) to check RMA report if
necessary.
