WARNING:
Please install BIOS F9i OFFICIAL version before installing this one
If you are already running BIOS F9i, then you may install the new BIOS directly
Double Warning:
YOU MUST BE RUNNING BIOS
F9i (
official version) BEFORE PROCEEDING. IF YOU FAIL TO MEET THIS CRITERIA, YOUR MOTHERBOARD WILL NOT BOOT.
Introduction:
When Gigabyte released their latest BIOS F9 (no letter after "9") they fixed some important security vulnerabilities and converted the BIOS into a "capsule" BIOS that we cannot downgrade.
@Elias64Fr has just released a new modified version of the F9i BIOS that includes the fix for "Major vulnerabilities" and also updates the Intel micro-code. More specifically, the modified F9i BIOS contains these changes:
The resulting file is called
Z390DESI_modMC_04282021_0906_Rev_0xEC_modME_12.0.81.1753.F9i, and it's attached below.
As always, the decision to use or not use this BIOS is up to you. It is entirely optional. I have tested the new BIOS for half a day now and found no issues.
Procedure:
This version can be flashed with
Q-Flash within BIOS Setup.
Once again, this you MUST be on BIOS F9i (official version) before you can install this modified version. Failure to follow this requirement will result in motherboard failing to boot. Install that version FIRST if you are not already on it.
If you are on the F9 (no letter) "capsule" BIOS, continue to use that version and do not install this version.
