Hi
I'm sure you reading the wrong chip 512K would be more like the ec:rom maybe if the computer was 15 years old the bios size was 512K check schematic for correct bios chip and use mine to reflash.

Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

Hello everyone,
I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details- Barebone / Chassis: TongFang GK7MRFR

Hello everyone,
I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.
When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.
I decided to try flashing a new BIOS, but since I didn’t want to desolder... -

Product Name: Razer Blade 15 (2022)
Product ID: RZ09-0421
Motherboard: CH580
BIOS Versions I work with: 2.02 & 2.06
Bios File Size: 32,768 KB
Dear Forum Readers!
I'm looking for a BIOS modder or anyone with experience who would give me suggestions about my razer blade's BIOS settings.
I can view and edit the content of the BIOS .bin file with AMIBCP BIOS editor.
The BIOS files I'm working with are from badcaps.net and those are CLEAN BIOS files (anyone can find it with the search string: RZ09-0421).
