Hello everyone,
I’m hoping someone can help me locate a verified original BIOS dump for my Acer laptop.
This is NOT a BIOS password removal request.
I’m looking for an original 32MB SPI BIOS dump to use as a reference in case my BIOS firmware is corrupted. My plan is to first dump and back up my own BIOS as soon as my programmer arrives. I am not planning to blindly flash someone else’s BIOS.
Laptop Information- Model: Acer Predator Triton 16 PT16-51-99GL
- Motherboard: DA0ZQDMB8AE Rev. E
- Main SPI flash: Winbond W25Q256JVEN (32MB)

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...07-02-2025, 02:31 PM -
Hi everyone! Hoping to gain some knowledge from this very helpful forum
. I'm new to this stuff and I'm obviously missing some important steps.
I have some Acer Spin SP514-54N laptops I wanted to make some changes to the BIOS for.
Using a CH341 USB Bios tool I read the bios successfully. Downloaded a backup copy. Copied that and opened it in a hex editor (HxD).
