MPS Import & Export & Modify Program :

1739567804966.jpeg






















































Connect the mps chip online using SCL,SDA,GND to the motherboard laptop , pc , gpu card
or solder your mps chip on the offline adapter and connect it to the programmer
Open the MPS software ( download link with the progammer ) , when it is not connected to the programmer, the following red message will showing [USB is not connected!
When the programmer is connected, the [USB is not connected!] will disappear
The programmer is connected to the chip through 3-pin plugs: black line: GND, SDA, SCL If you do not know which specific point, please check the datasheet of the chip or the schematic
Power on the target board, and then point to the SCAN search chip (Note: for online mode the chip must be energized to be recognized!)
Recognize the chip MP2886A, PMBUS address is 20H, Vendor lD is 25H.
If there is more than one chip, it will be displayed in the left list, click the title of the chip to select it
Click [Input], the window shows the basic parameters of the chip, the number of phases ,vboot,PWM-VID, FERQ,RC BOOT,,etc and you can modify them
Click [Reglster], in this interface backup program and write new program or mdify
Backup program: Click [Cur.Export] for the chip you choose
[Sys. Export] this option backup all chip read by the programmer , enter the name of the file to be saved and save it.
[Cur. Epot] is recommended so you can backup each chip seprated
Write Program: (The [Sys. Config] is directly written to the chip, The [Sys. cmd] needs to be written manually by us to facilitate the change of parameters after writing)
Method 1: Click [Sys. cmd], select the program file, open it, import the configuration, click [WRITE TO NVM], and write the program to the chip
Method 2: Click [Sys. Config], select the program file, open it, and then the program will be automatically written to the chip, then the program will be automatically written to the chip.

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.

Bios DA0P5HMB8I0 REV I

hello i need bios for DA0P5HMB8I0 REV WhatsApp Image 2025-04-04 at 13.11.53.jpeg I can u help?

Asus Rog G513QR

hello i have an asus rog g513qr ryzen 7 series 5000 that initial not powering on the cpu was damaged , after changing the CPU, bios was corupted and i write another, after we have image on display and windows i attached picture ,bios is damaged with bad serial u have picture (the ic grafic is nvidia 3070) do you think the grafic card fault is from bios or i have to solder the ic or replace the GPU IC?

is there a place to find a parts list and values for a schematic?

Looking for a parts list of mainly capacitors and their values for the schematic ASUS MAXIMUS IX HERO REV.1.0.1A.FZ
