[Mod request] X99S SLI PLUS ( Can pay for service )

[BDMaster]

I get It Module "Setup" 899407D7-99FE-43D8-9A21-79EC328CAC21 etc. IFR.txt !
And now what do You want to know ?
Have You saw the Falseclock Method (the actual way to modify NVRAM variables) :

https://www.bios-mods.com/forum/Thread-R...-EFI-shell

It's the species evolution, so to try We can use EFI tool and to make definitive We can edit
the IFR Code offsets !
Let me know

See the menu that starts at offset 0x35284, I believe i want to expose that.

Scrapping this project. Got a good deal on a Gigabyte X99 board.

Thanks for the help so far, i put something in your tip jar.

Sadly this was scrapped. I was hoping someone would accomplish this.

I want to try the suggestion from the previous page regarding changing NVRAM settings with SCEWIN. It seems possible to enable Above 4G decoding in the NVRAM settings, but I cannot write back to NVRAM with SCEWIN. It seems the NVRAM is locked. Does anyone know how to unlock it so I can try?

I have tried FalseClock's EFI nvram variable modifier, but I am not sure I used the right offset for the variables I want to modify. From the SCEWIN dump, I think I want to change to these settings:

Setup Question = MMIOHBase
Token =192 // Do NOT change this line
Offset =F76
Width =04
BIOS Default =[00]56T
Options =*[00]56T // Move "*" to the desired Option
[01]40T
[02]24T

Setup Question = MMIO High Size
Token =193 // Do NOT change this line
Offset =F7A
Width =04
BIOS Default =[03]1024G
Options =[00]256G // Move "*" to the desired Option
[01]128G
[02]512G
*[03]1024G

Setup Question = Above 4G Decoding
Token =330 // Do NOT change this line
Offset =227
Width =01
BIOS Default =[01]Enabled
Options =[00]Disabled // Move "*" to the desired Option
*[01]Enabled

For example I tried:
setup_var 0x227 0x01
to enable above 4G pcie / high bar / 64bit pcie address decoding on the x99s.
I see "error: offset is out of range" from FalseClock's shell.
My motivation is I want to try a xeon phi or K80 in this board (k40 works out of the box)

I guess the problem is an smi handler from MSI that blocks writing nvram. I found a suggestion here to patch the BIOS for this: but it seems too old and no longer works
