I am working on a CPU support upgrade for the Dell OptiPlex 3040 with H110 chipset, with the goal of adding support for a Coffee Lake mobile QQLT/MUTANT CPU.

The motherboard is based on the Intel H110 platform and originally supports Skylake* CPUs.

So far I have modified the BIOS/firmware with the following:

Enabled HAP in the Flash Descriptor.

Modified the Intel ME region using the proyect DeGuard.

Integrated the resulting ME region back into the image.

Modified the BIOS for Coffee Lake CPU support.

Added/modified the required CPU microcode.

Made the necessary Coffee Lake-related BIOS modifications

The modified BIOS has not yet been tested with a QQLT/MUTANT CPU, so this should be considered experimental.

Target CPU: Intel Coffee Lake mobile QQLT/MUTANT
Motherboard: Dell OptiPlex 3040 / H110
BIOS: Dell OptiPlex 3040 modified BIOS
ME: Intel CSME 11.6.0.1126 with deguard
BootGuard: HAP + DeGuard modifications applied

I am looking for someone with the same motherboard or compatible hardware who can test the modified BIOS with a QQLT or other Mutants cpus.

Because this is an experimental BIOS modification, an SPI programmer is recommended for recovery in case the system does not POST.

I can provide the modified BIOS and the original dump for comparison.

Any feedback regarding the Coffee Lake modifications or additional changes required for QQLT support would also be appreciated.

Thank you.

The laptop is currently non-POST and stops in pre-memory initialization, so I cannot use RU.EFI or UEFI Shell.

I need the BIOS modified to enable Intel DCI over USB3 DbC for hardware firmware debugging, preferably as early as possible during PEI/pre-memory initialization.

The Setup IFR contains:

Platform Debug Consent = USB3 DbC
CPU Run Control / Run Control Lock
PCH Trace Hub
USB Overcurrent Override for DbC
xDCI

Simply changing these NVRAM variables has not caused USB DbC enumeration.

Could you check the actual Intel PCH/FSP debug policy, DCI enable/HDCIEN, locks/fuses/Boot Guard coverage and modify the dump so USB3 DbC is really enabled during early boot?

I can provide the original SPI dump, extracted SetupUtility PE32, IFR dump and schematic.

BIOS chip: Macronix MX25L12872F (16MB, 3V)

Symptom: onboard soldered RAM is faulty. System freezes with horizontal black lines on screen. Confirmed with MemTest86 - test consistently hangs around 83% with visible artifacts.

Request: I need a patched BIOS that disables the faulty onboard RAM channel so the system can boot using only the DIMM1 socket (if populated) or the remaining healthy channel. I found an "ALT_DIMM1_CH0_CH1_EXPERIMENTAL" file online claiming to do this, but a byte-level diff against my own dump shows ~48% of the file differs across 70k+ regions - way more than a targeted RAM-disable patch should touch, so I don't trust it's based on the same firmware base as mine.

Attached is my own verified original dump, read and double-checked via CH341A (16,777,216 bytes, matches chip size, contains valid Lenovo/S145-1415IIL identifiers). Could someone patch THIS exact file to disable the bad RAM channel, rather than pointing me to a generic pre-made file?

last year the original steam deck LCD recieved an aftermarket oled screen called the DeckSight. this naturally comes with a modded bios to enable the screen. but the creator of the screen decided to saddle us with its own personal logo instead of keeping the original OEM Steam Deck bios logo. 




and he's been clear that's not gonna change.



Since the logo looks kind of tacky i would like to being able to use the OEM Steam Deck OLED logo.

I have an older Acer Predator Helios 300 PH317-53-72KP that I changed the screen panel in to a NE173QHM-NY1 V8.0 (1440p 165Hz).

It works, but the laptop's startup animation does not display correctly. If I disable it in the BIOS, it boots normally. No big deal, I don't really like the animation anyway.

However, in Windows 11 and Linux Mint the screen defaults to 1440p 60Hz. Using CRU, I managed to get 1440p 144Hz working perfectly in Windows. 1440p 165Hz also kind of worked, but the screen was glitchy. Maybe I had something set wrong in CRU, or the laptop simply can't do it. Adaptive Sync/VRR also does not work.

I'm wondering if the BIOS has some kind of panel whitelist or other display configuration that prevents the panel's EDID information from being passed through to the OS correctly.

If there is something like that and it is possible to remove or modify it, I would really appreciate it. Getting the panel working properly at 1440p 144Hz is the main thing I'm interested in. If 165Hz and Adaptive Sync/VRR can also be made to work, that would be great.

I would also be interested in unlocking the RTX 2070 Max-Q to a full RTX 2070, if possible, as well as better RAM/memory options and other useful hidden BIOS settings.

I dumped my BIOS using a CH341A. I made four reads and all four dumps are identical, and the chip is a Winbond W25Q128JV (16 MiB).

Thanks a ton in advance!]]>

The board uses an older AMI BIOS, not UEFI, but it also has ASUS Express Gate integrated into the BIOS. When Express Gate is enabled, the normal BIOS boot screen can hand control over to Express Gate, which effectively takes over the display and runs its own environment.
So instead of trying to completely replace the P6T's original BIOS, what if we used the Express Gate portion of the firmware as the entry point for a custom UEFI environment?
The basic idea would be:
P6T power-on → original AMI BIOS initializes hardware → Express Gate mechanism launches → custom UEFI environment takes its place → UEFI boot manager → Windows/Linux
The original ASUS BIOS could potentially remain responsible for the board-specific initialization:

• X58 chipset
  
• ICH10R
  
• CPU
  
• RAM
  
• PCIe
  
• SATA
  
• USB
  
• Super I/O
  
• etc.
  

Then the Express Gate environment would essentially be replaced by an EDK II/UEFI-based environment.
The goal wouldn't necessarily be to "convert the entire P6T BIOS into UEFI." It would be more like using something the existing firmware already knows how to launch as a bridge into a modern firmware environment.
Ideally, it could eventually provide things the original P6T never had:

• UEFI boot
  
• GPT boot
  
• NVMe boot
  
• modern UEFI drivers
  
• graphical firmware interface
  
• UEFI boot manager
  
• potentially Secure Boot
  
• modern hardware information
  

And the original legacy BIOS could potentially remain as a fallback/recovery environment.
Obviously, there are huge technical questions:
How does the P6T's AMI BIOS actually launch Express Gate?
Where exactly is Express Gate stored in the firmware?
How much space does it occupy?
Can that execution path be redirected to a UEFI payload?
Does the BIOS initialize enough hardware beforehand for UEFI to take over?
The P6T Deluxe is especially interesting because its BIOS is only 16 Mb (2 MB), so space would be a major constraint.
I'm wondering whether this is actually technically possible rather than simply assuming an old X58 board can never have UEFI.
The first step would probably be to dump/analyze the final P6T Deluxe BIOS 2209, locate the Express Gate module, understand its loader, and see exactly what ASUS is doing when Express Gate takes over.
Has anyone ever investigated replacing ASUS Express Gate with a custom firmware/UEFI payload on an older AMI BIOS board?

EDIT: Idea two would be Express Gate = Old Linux, edit or inject new linux but just uefi/bootloader/shell style with uefi support that can boot OS's (off sata/pcie)]]> I've been thinking about an idea for the ASUS P6T Deluxe.

And the original legacy BIOS could potentially remain as a fallback/recovery environment.
Obviously, there are huge technical questions:
How does the P6T's AMI BIOS actually launch Express Gate?
Where exactly is Express Gate stored in the firmware?
How much space does it occupy?
Can that execution path be redirected to a UEFI payload?
Does the BIOS initialize enough hardware beforehand for UEFI to take over?
The P6T Deluxe is especially interesting because its BIOS is only 16 Mb (2 MB), so space would be a major constraint.
I'm wondering whether this is actually technically possible rather than simply assuming an old X58 board can never have UEFI.
The first step would probably be to dump/analyze the final P6T Deluxe BIOS 2209, locate the Express Gate module, understand its loader, and see exactly what ASUS is doing when Express Gate takes over.
Has anyone ever investigated replacing ASUS Express Gate with a custom firmware/UEFI payload on an older AMI BIOS board?

EDIT: Idea two would be Express Gate = Old Linux, edit or inject new linux but just uefi/bootloader/shell style with uefi support that can boot OS's (off sata/pcie)]]>
