Bios Mods - The Best BIOS Update and Modification Source

Your CPU is an AMD and I cannot rewrite back the Bios Mod !
Only using an SPI Programmer with Clip is possible to make this job !

So a BIOS modification would not work for me at all?
The only solution is a programmer?

I've been looking through the BIOS all day with IDA, trying to find the whitelist.
The only interesting thing i've found is a module named: SystemErrorLogPei
It contains several strings that i'm trying to figure out what means:
"1000101010001010100010000"
"100010100010100010000"

They might just be references to some offsets, i'm not that used to assembly.
One offset is named: off_FFFA8DEC
Also the function: "sub_FFFA8F53" has 11 sub-routines it can go to.

That's just the things i've "found" so forth.

Anyway. I'll try to locate a programmer asap. Thanks for your help! Much appreciated!

Give a look to FalseClock Method too :

You can unlock some Variables into VarStore !

My CH341A programmer finally arrived in the mail today! Yeeey!
So how do i proceed now to get this whitelist problem fixed?

Ok friend,
here HMM :

Here Schematics :


You have to find the Chipset ENE and near It You will find the Eeprom Chip

Look on left side bottom . . .and You will see two 8 pins soic8 chips !
Then You have to check the serigraphy and write to me the name on !
Let me know

Here's my motherboard.
The soic8 chip with the red ring around it, is a Winbond chip: Serial:25Q64FVSIG
This is the only Winbond chip i could locate on the motherboard.
I'm guessing it's the right chip, as Google says it's a 64Mbit SPI flash chip, and my BIOS is 8MB (64Mb). Am i correct?

EDIT:NB! The serial number i posted was wrong, i have updated the post to show the real number!

Yes !

Sorry for using such a long time, but i had to connect my chip to the programmer without the clips!
But i finally managed it! 

Here is the BIOS image from the programmer: https://www.sendspace.com/file/rnj3mq

I used an English version of the CH341A programmer, and it worked great!
I'm actually quite impressed i managed to do this, without any issues at all!
Btw, i ran a checksum on this image from the programmer, and compared it with the normal bios dump, and it differed.
I'm guessing it's supposed to differ, right?

I successfully wrote your imagefile. But still got the same error: unauthorized device. :/
