3-3 Frequently Asked Questions
Question: What are the various types of memory that my mother-
board can support?
Answer:
The motherboard has six DIMM slots that support 184-pin, regis-
tered ECC DDR-266 or DDR-200 SDRAM DIMM modules. If using 533 MHz
processors, you must use DDR-266 memory (DDR-200 is not supported at a
533 MHz front side bus speed). It is strongly recommended that you do not
mix memory modules of different speeds and sizes. Unbuffered SDRAM,
non-ECC memory and PC100/133 SDRAM modules are not supported.
Question: How do I update my BIOS?
Answer:
It is recommended that you
do not
upgrade your BIOS if you are
experiencing no problems with your system. Updated BIOS files are located
on our web site (http://service.advantech.com.tw/eservice). Please check
our BIOS warning message and the info on how to update your BIOS on our
web site. Also, check the current BIOS revision and make sure it is newer
than your BIOS before downloading. Select your motherboard model and
download the BIOS file to your computer. Unzip the BIOS update file and
you will find the readme.txt (flash instructions), the phlash.bat (BIOS flash
utility), the platform.bin (platform file) and the BIOS image (xxxxxx.rom) files.
Copy these files onto a bootable floppy and reboot your system. It is not
necessary to set BIOS boot block protection jumpers on the motherboard.
Flash the boot block and enter the name of the update BIOS image file.
Question: Why can't I turn off the power using the momentary
power on/off switch?
Answer:
The instant power off function is controlled in BIOS by the Power
Button Mode setting. When the On/Off feature is enabled, the motherboard
will have instant off capabilities as long as the BIOS has control of the
system. When the Standby or Suspend feature is enabled or when the
BIOS is not in control such as during memory count (the first screen that
appears when the system is turned on), the momentary on/off switch must
be held for more than four seconds to shut down the system. This feature
is required to implement the ACPI features on the motherboard.
