Question: How do I update my BIOS?
Answer: We do NOT recommend that you upgrade your BIOS if you are not ex-
periencing any problems with your system. Updated BIOS les are located on our
website at http://www.supermicro.com/support/bios/. Please check our BIOS warn-
ing 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. You may choose the zip 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.bat BIOS-ROM-lename.xxx <Enter>
Note: Always use the le named “ash.bat” to update the BIOS, and
insert a space between "ash.bat" and the lename. The BIOS-ROM-
lename will bear the motherboard name (i.e., X10SRH-CF/CLN4F) and
build version as the extension. For example, "X10SRH-CF/CLN4F.115".
When completed, your system will automatically reboot.
When the BIOS ashing screen is completed, power off to reboot the
system. Power on and at this point, you will need to load the BIOS de-
faults. Press <Del> to go to the BIOS setup screen, and select "Restore
Defaults" to load the default settings. Next, press <F4> to save and exit.
Then reboot the system.
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.
