Acer Aspire 5920G - Requesting Modded BIOS (9600M GT) from .WPH for CH341A Flasher
Hello everyone,
I need help with my Acer Aspire 5920G laptop. Its original GeForce 8600M GT graphics card failed, so I replaced it with an Nvidia GeForce 9600M GT MXM card.
**Problem:** The laptop powers on, but there is no display (black screen) on either the internal LCD or external monitor. This indicates a BIOS compatibility issue with the new graphics card.
**What I have tried so far:**
1. I have my **original stock BIOS dump (1MB .BIN file)** from my laptop, which works and allows the laptop to power on normally (but no display with 9600M GT, as expected).
2. I found a **modded BIOS file (e.g., "5920G_MXM_V3.WPH")** that is supposedly for 5920G with MXM card upgrades.
3. I use a **CH341A programmer** to flash the BIOS chip.
**The Issue with the .WPH file:**
* The `.WPH` file is larger than my 1MB BIOS chip. My original BIOS is exactly 1MB (1048576 bytes).
* Comparing the `.WPH` file with my original BIOS, I found that:
* The beginning of the `.WPH` file is **identical** to my original 1MB BIOS.
* The `.WPH` file has **extra data at the end**, specifically from offset `00100000` up to `0010D630` (approx. 54KB additional data). I suspect this section contains the new VBIOS for the 9600M GT.
* I attempted to extract the BIOS region using UEFITool, but it gave a "not a single Volume Top File is found" error, indicating it cannot parse this specific `.WPH` structure for some reason.
* I also tried to manually cut the file with a hex editor based on the `000FFFF0` boundary, but the resulting BIOS did not work (laptop was completely dead, requiring a reflash of the original dump to recover).
* I tried flashing another 1MB .ROM file from an Extensa 5620G (also PM965 chipset, 8600M GT stock) that was modded for MXM, but it resulted in unexpected behavior (e.g., battery charge light on, no boot).
**My Request:**
Could someone please help me get a working 1MB `.BIN` or `.ROM` modded BIOS for my Acer Aspire 5920G that fully supports the Nvidia GeForce 9600M GT?
**Ideally, if possible:**
* Extract the correct 9600M GT VBIOS from the provided `.WPH` file (or provide a known working one).
* Inject/patch this VBIOS into my **original stock BIOS file** to ensure maximum compatibility with my specific laptop hardware.
Or even convert a WPH to bin!😓😅

Thank you very much for your time and help!
