Question: What type of memory does my motherboard support?
Answer: Please see Section 2-2 for a comprehensive answer.
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 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 current BIOS revision to make sure that it is newer than
your BIOS before downloading. 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 BIOS-ROM-lename
will bear the motherboard name (i.e., B1SA4) and build date code as the
extension. For example, "B1SA41.218". When completed, your system
will automatically reboot.
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.
Warning: Do not shut down or reset the system while updating the BIOS
to prevent possible system boot failure!
Note: The SPI BIOS chip installed on this motherboard is not removable.
To repair or replace a damaged BIOS chip, please send your motherboard
to RMA at Supermicro for service.
Question: I think my BIOS is corrupted. How can I recover my BIOS?
