M18xR1 2026 BIOS Update! Testers Needed!

[ssj92]

Following my M17xR3 bios, I have decided to release this one early. 

 

 

Attached is a bios made with time, effort, money, and love. This file is BUILD 285 (from M17xR3) ported to M18x!

***Alienware M18xR1 BIOS Version A26CS Changelog:***

-Updated CPU Microcode to latest available in 2026
-Updated Intel RST (RAID) OPROM to 13.5 which supports TRIM in RAID0 for SSDs
-Updated Intel iGPU vBIOS to v2171 
-Fixed PEG mode allowing Maxwell 2 (980M, 970M, M3000M, M4000M, M5000M) and Pascal (P5000, etc) to work (Turing is still not working in PEG eDP) [NOTE: Pascal doesn't work on LVDS display so for now, this is only true for M17xR3. Pascal DOES work in SG.]
-Fixed SG mode for Maxwell 2. Pascal and Turing work as well. Need amphere and ada testers!
-Some other changes I might have forgotten. I am still trying to port 16GB memory support, UEFI support, and potential Above 4G DECODE

I still have more plans to update these BIOS' but wanted to get some feedback at least since I don't have a inf amount of cards.

I was able to boot with Tesla m6 only! Amazing work. Just curious what did you fix to make Maxwell 2 to work?

Good to hear the bios works well. I haven't tested tesla m6. Is it in SG mode or PEG? PEG shouldn't work in M6 since it's missing display outputs. 

 

Do some more tests, run 3dmark firestrike to make sure the card actually clocks up. I haven't tested M18xR1 yet,but M17xR3 SG fix broke clocks and needed 100 more bios builds to fix. I ported the logic to M18x so it might work. 

 

PEG fix:
BIOS/display handoff patch so Maxwell can boot as primary GPU.

 

SG fix:
BIOS policy patch plus ACPI/AML porting so Intel graphics can own the display while the NVIDIA card is handled correctly as the secondary GPU.

Also I made a post for M18xR1 bios and M17xR3 bios

It is running at SG mode with 2920xm.

 

I have no idea what any of those are. But truly remarkable that you were able to make Maxwell work m18x.

 

i ran one stress test and my clocks were fine. But tesla m6 seemed to have a weird fan curve.

 

do you think this bios would help a single RTX 3000 to work in SG mode?

You can run rtx 3000 but it will be limited to dx11. For some reason dx12 doesn't work with intel hd 3000. I am still looking into that
