That one flashes but it's from 2018 and appears to not add anything new...
Looking at the file in Award Bios Editor it looks no different than OEM to me.
C0A9 on line 26 there is Micron NVMe Controller...
Just a interesting note to add.
I tried some of the other modded Gigabyte X58 BIOS's posted here just to see what they'd do and they show up as "BIOS ID check error" vs the "Invalid BIOS Image" that the correct one for GA-X58-USB3 shows up as in Q-Flash.
@İsmailTPC_Hastanesi I'm at a loss here.
FLASHSPI and Q-FLASH won’t flash it. They say it’s corrupt. They flash F5C from Gigabyte’s site just fine.
I've tried extracting the download with 7z, 64-bit WinRAR, and 32-Bit WinRAR all with the same "!!! Bad BIOS Image !!!" result while using a MS-DOS and FreeDOS boot USB made with Rufus...
After I flash this with @bios in Windows 10 and reboot I get a "checksum error" and my system reboots and loads the backup BIOS.
Am I doing something wrong or is there a issue with this file? I read in a previous post that someone else was having the same problem.
