3-3 Frequently Asked Questions
Question: What type of memory does my motherboard support?
Answer: The C2SBA+II/C2SBA+/C2SBA/C2SBE supports unbuffered, DDR2
667/800 MHz memory modules. See Section 2-4 for details on installing
memory.
Question: Why does Microsoft Windows XP (SP2) and Windows Vista show
less memory than what is physically installed?
Answer: Microsoft implemented a design change in Windows XP with Service
Pack 2 (SP2) and Windows Vista. This change is specic to the Physical Ad-
dress Extension (PAE) mode behavior which improves driver compatibility. For
more information, please read the following article at Microsoft’s Knowledge

Question: How do I update my BIOS?
Answer: It is recommended that you do not upgrade your BIOS if you are not
experiencing any problems with your system. Updated BIOS les are located
on our web site at http://www.supermicro.com/support/bios/. Please check our
BIOS warning message and the information on how to update your BIOS on our
web site. Select your motherboard model and download the BIOS (.rom) le to
your computer. Also, check the current BIOS revision and make sure that it is
newer than your BIOS before downloading. You may choose the zip le or the
.exe le. If you choose the zipped BIOS le, please unzip the BIOS le onto a
bootable device or a USB pen/thumb drive. To ash the BIOS, run the batch
le named "ash.bat" with the new BIOS .rom le from your bootable device or
USB pen/thumb drive. Use the following format:
F:\> ash xxxxxxxx.rom <Enter>
Note: Be sure to insert a space immediately after "ash" and use only the le
named “ash.bat” to update the BIOS.
