WADE-8022 User’s Manual
5-3
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.
