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 files are located on our website at
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
file 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 file and the .exe file. If
you choose the zip BIOS file, please unzip the BIOS file onto a bootable USB device. Run
the batch file using the format FLASH.BAT filename.rom from your bootable USB device to
flash 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 BIOS by the Power Button Mode
setting. 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 first 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.
3.4 Returning Merchandise for Service
A receipt or copy of your invoice marked with the date of purchase is required before any
warranty service will be rendered. You can obtain service by calling your vendor for a Returned
Merchandise Authorization (RMA) number. When returning to the manufacturer, the RMA
number should be prominently displayed on the outside of the shipping carton and mailed
prepaid or hand-carried. Shipping and handling charges will be applied for all orders that
must be mailed when service is complete.
For faster service, RMA authorizations may be requested online
support/rma/).
