Question: What type of memory does my motherboard support?

Question: How do I update my BIOS?
Answer: We do NOT recommend that you upgrade your BIOS if you are
not experiencing any problems with your system. Updated BIOS les are
located on our website 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 cur-
rent BIOS revision to 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
"ami.bat" with the new BIOS ROM le from your bootable device or USB
pen/thumb drive. Use the following format:
F:\> ami.bat BIOS-ROM-lename.xxx <Enter>
Note: Always use the le named “ami.bat” to update the BIOS,
and insert a space between "ami.bat" and the lename. The BI-
OS-ROM-lename will bear the motherboard name (i.e., CZ390)
and build version as the extension. For example, "C9Z390.115".
When completed, your system will automatically reboot.
If you choose the .exe le, please run the .exe le under Win-
dows to create the BIOS ash oppy disk. Insert the oppy disk
into the system you wish to ash the BIOS. Then, boot the sys-
tem to the oppy disk. The BIOS utility will automatically ash
the BIOS without any prompts. Please note that this process
may take a few minutes to complete. Do not be concerned if
the screen is paused for a few minutes.
When the BIOS ashing screen is completed, the system will
reboot and will show “Press F1 or F2”. At this point, you will
need to load the BIOS defaults. Press <F1> to go to the BIOS
setup screen, and press <F9> to load the default settings. Next,
press <F10> to save and exit. The system will then reboot.
Attention! Do not shut down or reset the system while updating
the BIOS to prevent possible system boot failure!
