BIOS Setup Information
WADE-8022 User’s Manual 4-1
Chapter 4
BIOS Setup Information
WADE-8022 uses AMI BIOS structure stored in Flash ROM. These BIOS has a
built-in Setup program that allows users to modify the basic system configuration
easily. This type of information is stored in CMOS RAM so that it is retained
during power-off periods. When system is turned on, WADE-8022 communicates
with peripheral devices and checks its hardware resources against the

Troubleshooting
This chapter provides a few useful tips to quickly get WADE-8022 running with
success. As basic hardware installation has been addressed in Chapter 2, this chapter
will primarily focus on system integration issues, in terms of BIOS setting, and OS
diagnostics.
5.1 Hardware Quick Installation
ATX Power Setting
Unlike other Mini-ITX board computer, WADE-8022 supports ATX only. Therefore,
there is no other setting that really needs to be set up. You must connect to J1 (12V DC
Jack) or J10 (ATX 4Pin 12V Power Connector) to let WADE-8022 power on.
ATX Power emulation AT Mode
You can adjust the JP5 to 1-2 short to emulation the AT mode.
It can let system auto power on when J1 or J10 has been detected your power source
directly.
JP5: ATX / AT Mode Select
PIN No. Signal Description
1-2 short ATX emulation AT mode
1-2 open ATX mode
Please note that you still need to use 12V adapter or ATX power supply to use!!
Serial ATA Hard Disk Setting for IDE/AHCI/RAID
Unlike IDE bus, each Serial ATA channel can only connect to one SATA hard disk at a
time; there are total four connectors, J33, J34, J35, J36 SATAIII (6Gb/s) ports on-board.
The SATA hard disk doesn’t require setting up Master and Slave, which can reduce
mistake of hardware installation. All you need to operate IDE, AHCI or RAID
(0,1,5,10) application for system, please follow up setting guide in BIOS
programming (Table 5-1); Furthermore, you can consult chapter 4.3
Advanced “SATA Configuration” part of the” SATA Mode Selection”.

5.2 BIOS Setting
It is assumed that users have correctly adopted modules and connected all the
devices cables required before turning on ATX power. 204-pin DDR3 SO-DIMM
Memory, keyboard, mouse, SATA hard disk, DVI-I connector, device power cables,
ATX accessories are good examples that deserve attention. With no assurance of
properly and correctly accommodating these modules and devices, it is very possible
to encounter system failures that result in malfunction of any device.
To make sure that you have a successful start with WADE-8022, it is recommended,
when going with the boot-up sequence, to hit “Del” or “Esc” key and enter the BIOS
setup menu to tune up a stable BIOS configuration so that you can wake up your
system far well.
Loading the default optimal setting
When prompted with the main setup menu, please scroll down to “Restore
Defaults”, press “Enter” and select “Yes” to load in default optimal BIOS setup. This
will force your BIOS setting back to the initial factory configuration. It is
recommended to do this so you can be sure the system is running with the BIOS
setting that Portwell has highly endorsed. As a matter of fact, users can load the
default BIOS setting any time when system appears to be unstable in boot up
sequence.
Improper Disable Operation
There are too many occasions where users disable a certain device/feature in one
application through BIOS setting. These variables may not be set back to the original
values when needed. These devices/features will certainly fail to be detected.
When the above conditions happen, it is strongly recommended to check the BIOS
settings. Make sure certain items are set as they should be. These include the Serial
Port1/ Serial Port 2 ports, USB ports, external cache, on-board VGA and Ethernet.
It is also very common that users would like to disable a certain device/port to
release IRQ resource. A few good examples are
Disable Serial Port1 to release IRQ #4
Disable Serial Port2 to release IRQ #3
Etc…
A quick review of the basic IRQ mapping is given below for your reference.
It is then very easy to find out which IRQ resource is ready for additional peripherals.
If IRQ resource is not enough, please disable some devices listed above to release
further IRQ numbers.
