Re: GIGABYTE Modified Bios

Hi Stasio,

Is there a modified BIOS for Gigabyte Z77X-UD5H, which includes patches against Spectre / Meltdown vulnerabilities ?
The latest official BIOS F16j (released on 2017-11-14) only fixes the MATS table for installing MacOS.
I know this board is pretty old now, but I hope you or someone else were able to insert the new Intel microCode to fix those vulnerabilities.

I am new to this forum and registered just so I can ask: could I get a modded bios for my Z97X-UD3H?

+1 Looking for the exact same modded BIOS here for that mobo. Any one willing to mod it would be highly appreciated :).

GA-Z77X-UD3H Meltdown+Spectre

A few days ago and confirmed tonight, it doesn't look like Gigabyte is going to patch the old GA-Z77X-UD3H motherboard I have here for Meltdown and Spectre beyond F20e. I hope I am wrong though.

I have not tried it yet but figured out how to patch the BIOSs myself. Am going to keep waiting a bit to see if MS patches it in Win 10 but in the mean time figured I would offer these up if anyone has a spare PC to try it on please do so and let me know. I have the original F20e BIOS and the modified BIOS from the first page; sha256 and md5 checksums are in the folder here but I'll repeat them just so you know for sure:

If this works then great; I will eventually pick one and replace mine as well. If your computer has problems let me/us know, I tried...

Re: GIGABYTE Modified Bios

Greetings!

I have an older motherboard & CPU. a Gigabyte GA-78LMT-S2P F4b (REV 5.1) [ USB 2.0 ]
Chipset:AMD 9600 rev 0 / 780G
SouthBridge: SB700
LPCIO: IT8728
Processor: AMD FX 4100 Family: F Model: 1 Step: 2 Ext Family:15 Ext Model: 1 Revision: OR-B2 (4 Cores x 4 Threads)
BIOS Type: Award ID:04/26/2013-RS780L-SB710-7A66CG0QC-00
I have disabled the Internal GPU and have an AMD R7 360 (2GB) installed (PC PARTNER).


Orig Bios HERE

The entire line of bios nerfs AMD-V's One is unable to select the correct options. It shows as ready but is not active. Virtual box, Hyper-V complain.
{I think the MSR's are not set correctly, and there is no Bios option enabled to be able to set the buggers.}
I would like to request some help and or some information to be able to alter my bios.
First, I would like to enable the options to enable the damn AMD-V and its kin.
Second, to possibly update the microcode. This computer acts 'weird' at times, the USB hub likes to reset, I've had to clear the DMI a few times...

I hope this board is not too old...

Re: GIGABYTE Modified Bios

Hey there stasio!

I have the GA-Z97MX-Gaming 5 motherboard. Saw you posted a moded F4 bios in this thread but I updated to F6 and can't downgrade to F4. Can you please mod the latest F6 bios for this motherboard? Also, seeing your F4 bios notes, what does it specifically mean? Like, you updated the killer network from 2.1.1.1 to 2.1.1.5? Is it a driver on the motherboard?

Thanks in anticipation!!!

Re: GIGABYTE Modified Bios

Hi guys!
I don't know if somebody posted it yet, so I updated the Z77X-D3H's bios to the latest microcode for spectre patch.
The base is the bios from first post: Z77X-D3H BIOS F18i mod.
I flashed it with Q-Flash.

CPU MicroCode updated:
Sandy (CPUID 206A7) microcode version 2D (07-02-2018) and Ivy (CPUID 306A9) microcode version 1F (07-02-2018)

Re: GIGABYTE Modified Bios

Hi Stasio, I already contacted the gigabyte support before speaking to you here and so far have not responded.

Ask me a question, does this difference in the IIRC between the motherboard rev 1.0 and 1.1 is at the software or hardware level?

[stasio]

Re: GIGABYTE Modified Bios

I found that main difference with Rev.1.1 is the updated power supply IIRC stage on the board, which suit Xeon.
Btw,
for clarification ask GB technical support.

Re: GIGABYTE Modified Bios

Hello, Stasio.

I am using the Xeon processor 2680 v2 final retail version manufactured in costa rica.

I tested the bios that you sent me and the computer turns on for 3 seconds and restarts, turns on for 3 seconds and restarts again without end.

I did not understand the reason the f21 bios did not work, you showed that it has the microcode of the Xeon 2680 v2 in thesis was to work.

I saw on the gigabyte website that the GA x79 ud3 rev 1.1 supports Xeon 2680 v2 from the bios f20, but I do not understand why it did not work on ga x79 ud3 rev 1.0, they are practically the same boards.

Please if you get a way and edit a bios especially for the Xeon 2680 v2, I will be very grateful.

Thank you Stasio!

Re: GIGABYTE Modified Bios

Your CPU is retail ?
What didn't work...? boot or something else..?
I found one modded F21e , try and this is my last resort,no other option.....

Re: GIGABYTE Modified Bios

@Stasio

UP!

Hi Stasio, how are you?

I tested the F20 bios of the gigabyte site and the bios F21E downloaded by the forum anandtech, the GA x79 UD3 rev 1.0 with the Xeon 2680 v2 did not work, I would like you to send me the most updated version of the bios F21E you have there.

Thank you!

[james_bond2015]

Re: GIGABYTE Modified Bios

Thanks for the explanations,

Can you make the bios f21e link available to you?

I wish you a good weekend for you and your family.
