Nice.
Just posting my specs, I have decided to use the CH341 Programmer:
System Model: OMEN by HP Laptop 17t-cm200
(HP official website does not see 17T-CM200 as an actual model prob because it got discontinued, it is recognized as 17T-CK2000)
System SKU: 70W93AV
Bios: F.12
Motherboard: 8BAD
I am gonna post photos of the MicroChips I believe are bios chips soon.
I have managed to get the CH341A Programmer, I also found out that I have 2 winbond IC chips which i assume to be BIOS chips. One is near the CPU which as I have read from many threads (IC Bios chips are usually closest to the CPU) and one is the image that MeatWar showed. I think I will read both of the chips and compare which oneâs data has something similar to that of Bios to determine which one is correct.
What are the types of these two chips?
Both are WindBond Chips
I am about to upload images of them
My Bad, I thought both are WinBond, only one of them is WinBond and the 2nd one is MX.
MX Chip at the Far Edge:
WinBond Chip Near CPU:
So Now I am trying to read the BIOS chip with CH341A. I used 1.8v Adapter because specs say 1.65V-1.9V the Chip operates on. The software detects it, it thatâs there isnât the Chip in the library of AsProgrammer that I am reading with. It only gives me W25Q16FW
Nvm, I just decided to follow by the Base IC âW25Q16â, It does read the chip. Hope I am doing it right.
Just a quick update:
I checked both chips mentioned, one WinBond and another Macronix
CH341A managed to pickup the Macronix chip unlike WinBond for which I had to choose the âBaseâ type.
Trying to extract and check the data from WinBond Chip gave me 2MB file with something I am unsure of, whether itâs a security thing or not. I am uploading it here.
Extracting the Macronix gave me a 16MB file with turned out to be BIOS files, So I just took the F.11 and pushed it to the Macronix chip.
Just to note, ME and TPM are still undetected and corrupted.
Now what I wonder is:
Could that WinBond Chip store the TPM / ME ( I believe this is unlikely for TPM due to Specs for this series laptop being fTPM " Firmware Based TPM" )

NVidia vbiosâŚkeep working, youâre ridding the âhorseâ like a cowboyâŚhope the âfuelâ doesnât run out!!!
Now⌠still without the user provided any clear HP motherboard identification/usefull full photos⌠theres a couple of more IC on the rigth of memory banks, at least one, keep digging.
EDIT: ALELUIAAAAAAâŚwe got âPICTURESââŚdamm sir, was this so hard to take out the ram stick??? Itâs not always like this on all mbs, thatâs for sureâŚ
HP G3LC is indeed an HP Mb Dscrtx408012gbfgsyni913900h (N35245-601)
BIN files are data⌠data is coded, code can be viewed with specific tools, some not public and other utilities like an Hex editor for ex, dis(a)assembler etc⌠youâre not on that point yet to put the wagon on front of the horsesâŚ
That smaller IC is a voltage regulator, thereâs another IC below the M.2 slot and seems not any more visible at first sight, that can be an EC/TPM/THB etc⌠unless on the other side of the board.
EDIT:
No you cannot, what or who indulge you to believe that UEFI tool can read/decompose and identify all kind of content, this is a PHY SIO component controller and indeed it may be THB relatedâŚas its a 1Mb data content, traces of it can be viewed with a HeX Editor.
There sure is some more IC chip:
This IC Chip is both near the CPU and the SSD Slot. I am going to attempt to read them both.
Also could you tell me what that tool is to read the .Bin files? Thanks.
All useful Images I can provide currently:
Sorry for the Picture Quality, my phone canât do better.
I think I found Bingo. They hid it under a piece of tape. (Might be wrong since itâs near the USB-C Thunderbolt and this just might be the Thunderbolt controller. The other IC Chips i showed previously are some Power Control chips with no data i could get from.
Now I extracted the files inside and still cant view them on UEFITools.

I went a bit further and took the Mobo off, so signs of the chip on the back side of the Mobo.
