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 fi les are located on our website at
http://www.
supermicro.com
. 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
fi le to your computer. Also, check the current BIOS revision to make sure that it is newer
than your BIOS before downloading. You can choose from the zip fi le and the .exe fi le. If
you choose the zip BIOS fi le, please unzip the BIOS fi le onto a bootable USB device. Run
the batch fi le using the format FLASH.BAT fi lename.rom from your bootable USB device to
fl ash the BIOS. Then, your system will automatically reboot.
Question: Why can't I turn off the power using the momentary power on/off switch?
Answer: The instant power off function is controlled in the BIOS by the Power Button Mode
setting (in the Advanced submenu). When the On/Off feature is enabled, the motherboard
will have instant off capabilities as long as the BIOS has control of the system. When the
Standby or Suspend feature is enabled or when the BIOS is not in control such as during
memory count (the fi rst screen that appears when the system is turned on), the momentary
on/off switch must be held for more than four seconds to shut down the system. This feature
is required to implement the ACPI features on the motherboard.
