Troubleshooting
WADE-8075 / WADE-8076 User’s Manual 5-2
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. CPU, CPU Fan, 204-pin DDR3
SDRAM, keyboard, mouse, floppy drive, SATA hard disk , 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-8075, it is recommended,
when going with the boot-up sequence, to hit “DEL” 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 “Y” 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 COM1/
COM2 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 COM1 serial port to release IRQ #4
Disable COM2 serial port to release IRQ #3
Etc…
