I wish to upgrade the ram to 8 or 16gb (if it support) and put a faster cpu like the i5-2520m or i7-2620m or even the i7-2630QM and for this i need the last update available all this parts are very cheap in this days and for my son will be fine.

If anyone could help me, I would be very grateful, or even give some suggestions to get more out of the C850.

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?

Happy to provide any additional info needed (EC version, etc.). Thanks in advance.

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.

i tried visiting premamods website but didnt see much there I remember back in the day he was popular for doing BIOS unlocks i'm not sure if it's still a thing now though or if my model is even compatible I can't even find a page that shows drivers for this thing I had to use a program to download all the drivers for me I can't even find bias updates this thing is super generic lol. not to sure how to upload a bios to have a look at. oh and i already tried the fn+r+n combo too

I have an HP ZBook Studio 15.6 inch G8 with a BIOS password lock that I've been trying to remove.

My unit:
- Model: HP ZBook Studio 15.6 inch G8
- Product ID: 553R1UC#ABU
- Serial: CND2061CZ3
- Board: LA-K721P (Compal)
- BIOS family: T92
- BIOS chip: Winbond 25Q256JVEN (U6, 32MB)
- EC chip: Winbond 25Q256JVEN (UK2, 32MB)

What I've tried so far:
- A forum member kindly patched my EC (UK2) — password removed, that worked.
- I also tried a set from a 62T25EA model (same board, same T92 family). With that set, all storage devices (NVMe + USB) are detected and the laptop boots into Linux Mint. However:
- I get an HP Endpoint Security Controller (ESC) error on every boot
- The AC adapter is recognized as "Unknown" — battery only charges when the laptop is powered off
- The original BIOS from my own dump (with serial changed) doesn't detect any storage devices at all (no NVMe, no USB)

What I need:
A virgin/dev BIOS (U6, 32MB) for the T92 family — ideally from a service manual, HP factory image, or someone with the exact same 553R1UC model. No serial, no password, no DMI data — just a clean BIOS that I can flash and then program the DMI myself.

If anyone has a clean BIOS dump or factory image for this board, I'd really appreciate it. I have my original dumps attached in my previous post for reference.

Thanks in advance!

System information:
  • Manufacturer: Hewlett-Packard
  • Model: HP Pavilion dv6-3110ST
  • SKU: XR556EA#AB8
  • BIOS: InsydeH2O F.29
  • BIOS version: F.29
  • BIOS type: InsydeH2O
  • Motherboard: HP 144A
  • CPU: Intel Core i5 M 460 @ 2.53 GHz
  • RAM: 4 GB
I would like to unlock the hidden/Advanced BIOS menus and settings.
I am particularly interested in Advanced, Chipset, CPU, Power, SATA, PCIe and graphics-related settings, if they are present but hidden in the firmware.
I am not looking for only the normal HP BIOS update. I am specifically requesting a properly modified/unlocked BIOS based on my exact F.29 firmware.
I can provide an original BIOS dump if required.
I understand that flashing a modified BIOS can brick the laptop, so I would like to know the safest method and whether this BIOS is actually moddable before flashing anything.
Thank you.]]> I would like to request an unlocked/modded BIOS for my HP Pavilion dv6-3110ST.

I have got an IBM Aptiva 2168-931 (Service Level H) with an rather unusual Opti Viper PCI chipset. With a custom VRM-Module from Necroware it is possible to employ every conceivable Socket-7-CPU, up to an AMD K6 3+ with 400 MHz. The respective CPUs are shown in BIOS as "Pentium" - which is fine with me.

There is one catch: the mainboard accepts CPUs to a clock frequency of 166 MHz. Even a non-MMX 200 MHz Pentium will produce an error 127, the CPU-Frequency is then recognized with 0 MHz. However, after exiting the BIOS, the PC runs fine, regardless of the frequency.

IBM-Aptiva_2168_Service-Level-H_BGOGR1L_6800_original.bin has bin extracted from an M28F101-150K1 -chip, using a T48.

Aptiva_2168-931_BIOS.zip is the product of mflash.exe, that produces a diskette-image for booting an IBM flash-program, that invokes a multi-language flash-process.

Perhaps there might be a possibility to alter this BIOS, so that CPUs > 166 MHz won't issue an error 127.


Cheers

On this machine, there has been a German version installed. BGO__1L ist the latest BIOS version for this computer. "__" stands for the respective language-codes.
