I am using a Gigabyte GA-Z68MA-D2H-B3 motherboard on my computer. I wanted to migrate from Award BIOS to UEFI. I downloaded the binary file from the Gigabyte product page, but when I tried to run, it says the the executable is not compatible with 64 bit versions of Windows. (I am using Windows 7 Ultimate 64 bits).
I sent an e-mail to Gigabyte, and today I received an answer:
Thank you for your kindly mail and inquiry. About the issue you mentioned, to update BIOS, you should be able to update it under DOS mode. After flash BIOS to UEFI, a warning message will appear: “Please shutdown and unplug power cord then plug back in order to complete BIOS update” Need to follow this instruction to complete the update.
I don't know how to enter the DOS mode. Please, could anyone explain me?
