Clear BIOS Asus Rog G531GU

Hello! Hi, I dumped my password protected BIOS. I flashed a new BIOS from this site (https://www.alexlaptoprepair.com/forums/threads/asus-rog-g531gu-g531gw-1-6-bios-dump.3918/), and everything works fine. I don't see the Mac address and PC serial number available on the BIOS screen. I have these details, but I don't know how to enter them into the new BIOS. I'm attaching the original dump and the clean BIOS from this site.

I kindly ask if it is possible to remove the password from the original BIOS or update the clean BIOS with the PC serial number and the Mac address.
thank you !!

USB-C Line Tracer and Tail Plug Detector – Laptop Dock Tester Tool



This compact USB‑C tester plugs directly into a port to probe every signal line, using the internal ESD protection diodes of connected TYPE-C ICs OR PD CONTROLLER. You can directly check the USB-C Port and all lines connecting to the Type-C chip directly or PD chip , and also know what protocol is activated on this input.
The tester can check all these pins

Power & Configuration
CC1, CC2 (A5, B5): Configuration Channel – determines plug orientation, establishes host/device role, negotiates power level, and signals alternate modes.
Data PINS
D+, D- (A6, A7, B6, B7): USB 2.0 differential pairs – always connected regardless of plug orientation.
TX/RX pairs (A2/A3/A10/A11 and B2/B3/B10/B11): SuperSpeed signals for:
USB 3.1 Gen 1/2
Thunderbolt 3/4
DisplayPort (via Alt Mode)
These lines are flipped depending on plug orientation.
Sideband / Auxiliary
SBU1, SBU2 (A8, B8):
DisplayPort Alt Mode (AUX channel)
Analog audio (e.g., headphone dongles)
USB Debug Accessory Mode (UART)


No HS, SBU, or CC → No CC negotiation; no PD connection .
HS detected, SBU absent → Likely USB‑3.x only.
HS & SBU detected → Indicates support for DP/Thunderbolt or USB‑3.x with SBU-based features.
SBU only → Debug or audio path present, but no USB‑3.x.

MPS PMBUS PASSWORD PROTECTION

MPS PMBUS PASSWORD PROTECTION
1000068222.jpg
Do processor circuit ICs (VRM) really have passwords?
Do you remember the video where I explained how to program modern processor circuit ICs using a PMBUS programmer? I mentioned at the time that in some cases, we would need the schematic, because even though there are many dump files available now, for some models it’s not possible to backup the file from another board because the ic is protected.

This is because some modern processor VRM ICs support a feature called PMBUS Protect. This feature allows the manufacturer to set a password to protect the IC. It provides three levels of protection:
  1. Protection from reading the registers
  2. Protection from writing to the registers
  3. Protection from both reading and writing to the registers
For the first and third types, it's not possible to take a backup from the IC—even if you have a working board with the same model. In this case, you’ll need the schematic to manually build a configuration that suits the processor circuit and its components.

As for the second type, you can still take a backup and write it to a new or used VRM IC later without any issues.

Are there any ways to break this protection? No.

Are there any workarounds to bypass it? No.
