currently, can't update BIOS by press F7 at POST.
I understand that you are trying to flash the BIOS on your Intel(R) Desktop Board DQ77MK.
In regards to your question, the BIOS version 0034 is the original release BIOS version, how can you be updating the BIOS to the original version that you already have on your motherboard?
Please provide more information regarding the procedure that you are trying to accomplish to be able to assist you further.
0034 is the first release, but the original BIOS version is 0026 (or 0024).
When i use executable file to run and flash the BIOS from Windows, it is OK.
My mentioned case is that: i want to update BIOS by press F7 at POST (EFI). When enter boot EFI, system is frozen.
Please let me know if you have any more question.
