Question: How do I update my BIOS under UEFI Shell?
Answer:
It is recommended that you do not upgrade your BIOS if you are not experiencing
any problems with your system. Updated BIOS files are located on our website at
www.supermicro.com/ResourceApps/BIOS_IPMI_Intel.html
. Please check our BIOS warning
message and the information on how to update your BIOS on our website. Select your
motherboard model and download the BIOS file to your computer. Also, check the current
BIOS revision to make sure that it is newer than your BIOS before downloading. To update
your BIOS under the UEFI shell, please unzip the BIOS file onto a USB device formatted
with the FAT/FAT32 file system. When the UEFI shell prompt appears, type fs# to change
the device directory path. Go to the directory that contains the BIOS package you extracted
earlier. Enter flash.nsh BIOSname#.### at the prompt to start the BIOS update process.
Reboot the system when you see the message that BIOS update has completed. Refer to
UEFI BIOS Recovery and/or the readme file for more information
