I'm trying to recover a Samsung Galaxy Book3 Ultra (NP960XFH) motherboard after a BIOS corruption issue.

I have the official Samsung BIOS update file downloaded through Samsung Update: P07ALQ.EXE

The file cannot be opened with 7-Zip or WinRAR. When I run it with parameters such as: 

P07ALQ.EXE /extract 
P07ALQ.EXE /a 
P07ALQ.EXE /?

it simply launches the BIOS updater instead of extracting any files.

My goal is to obtain the actual BIOS image (.bin, .fd, . rom, etc.).

How to extract the firmware image from P07ALQ.EXE?

or

Does anyone have the extracted BIOS file itself?

Thanks!]]> Hello everyone,

I’m not sure if this is possible, but I’m running a Lenovo ThinkCentre M90n-1 as an unattended embedded device. Occasionally on boot the AMI BIOS halts on a POST error (e.g., 0135 - fan failure) with the "Press F1 to enter Setup, F2 to resume". Since the unit is headless, it sits there until someone physically presses a key. Is there anyway to make the BIOS always continue on non-fatal POST errors without user input? The ROM file is attached.

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!]]>

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!

I'm stuck on a BIOS password issue on an industrial embedded PC and would really appreciate some expert eyes on this. I've done what I can with hex editing but I think the real password check is elsewhere in the firmware, beyond my current skill level.

Hardware:

Device: Advantech UNO-1372G-J (industrial fanless PC / OPC)
Motherboard: UNOB-2117MB REV.A1, made in Taiwan, PN 19A3211703-01
CPU: Intel (embedded SoC, soldered)
Main BIOS flash chip: Winbond W25Q64JW (8MB, SOIC-8, 1.8V)

Problem:
The BIOS requires a password at boot/setup entry. Clearing CMOS (battery pull + CN36 clear-CMOS jumper + shorting battery socket V+/V-) has no effect on the password — as expected, since on these AMI Aptio boards it's stored in SPI flash rather than battery-backed CMOS.

What I've tried so far:


Dumped the main BIOS chip (W25Q64JW) via CH341A + 1.8V adapter + SOIC-8 clip. Read 3 times, MD5-verified identical each time.
Located what appears to be the AMI TSE (Total Setup Edition) password-related NVAR variables in the dump:

AMITSESetup NVAR entry (offset ~0x300281) with all-zero data (looks like a "default/empty" instance)
A second AMITSESetup NVAR entry (offset ~0x302931, size 0x68) containing non-zero data — what I assumed to be password hash material (80 bytes, structured as two overlapping ~40-byte sequences)
An OEMDEFAULTPWDSetup NVAR entry (offset ~0x302999) with a single data byte (0x04, later noticed value 0x70 depending on offset interpretation — I may have made an error here)

Tried zeroing the 64 then 80 bytes of the suspected hash data in the second AMITSESetup NVAR — reflashed, no change, password still requested.
Tried invalidating the NVAR entries entirely by changing the state byte from FF FF FF to 3C FF FF on both AMITSESetup and OEMDEFAULTPWDSetup entries — reflashed, verified the re-dump matched the written image exactly (MD5 identical), so the write itself succeeded with no write-protection issue — but the password prompt is still there.

So the chip write/erase/verify cycle works fine (no WP/lock issue), but neither approach neutralizes the actual password check. My guess is either:

The AMITSESetup varstore I found is just the general Setup form storage (all BIOS settings), not specifically the password, and the real password hash is stored/checked elsewhere (different GUID, different NVAR name, or computed by DXE/PEI driver code rather than a plain stored hash)
There's some checksum/CRC over the NVRAM volume that needs to be recalculated after modification, and an invalid checksum causes the driver to fall back to a "locked" state rather than "no password"

What I'm hoping for:


Guidance on identifying the correct NVAR GUID/variable that AMI Aptio uses for password verification, as opposed to general Setup storage
Whether AMIBCP (AMI BIOS Configuration Program) can open/patch this dump properly, since UEFITool NE reports "Stores not found" on this image
Any known quirks specific to Advantech's AMI Aptio implementation


I have the original untouched dump and full change logs for every attempt. Happy to upload the original .bin if that helps, and I can provide any additional dumps/photos of the board on request.

Thanks in advance for any pointers!]]>

Whether AMIBCP (AMI BIOS Configuration Program) can open/patch this dump properly, since UEFITool NE reports "Stores not found" on this image
Any known quirks specific to Advantech's AMI Aptio implementation


I have the original untouched dump and full change logs for every attempt. Happy to upload the original .bin if that helps, and I can provide any additional dumps/photos of the board on request.

Thanks in advance for any pointers!]]> https://www.bios-mods.com/forum/Thread-DV6-1140ES-bios-request Sun, 12 Jul 2026 07:19:12 -0400 danitzoi]]> https://www.bios-mods.com/forum/Thread-DV6-1140ES-bios-request For those that believe that can help me in any way here are the details:
