          Hi, I've been reading the forum and I know that before I ask my question I need to give all the necessary information, so before I ask my full question could you tell me how I can find the following data:

          Serial: PF39977K
          Model name: Legion 5 15ACH6H
          Main Board: NM-D562 Rev:3
          BIOS: 74M12JWS1Q (W25Q128FW), (UB3, 16MB)
          BIOS : W25Q16DW (UG10, 2MB)

          This is an example of what I saw, it's not from my PC, but I would like to know how I can find that data on my PC

            you have a label on the laptop case for the name and model S/N, etc.. for the motherboard model you have to open your laptop and it is written on the motherboard usually with white paint, there you will also find the bios chips.. for writing or flashing the content on the chip ...ou need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

            Due to a lack of donations, server free space at a critical level, and possible closure of Bios Requests all donations are welcome, click:

                          When I opened the PC I saw that there are two chips that say Winbond, do I have to install the BIOS on both? Or is there a thread that explains how to flash a Legion 5 Pro-16ACH6H?

                          Will the ch341a programmer work for my PC? I have read in other threads that they use it for the normal Lenovo Legion 5, but I don't know if it will work for the pro

                            I don't know either, I haven't used this programmer..go into the programmer's database (you can find it on the internet) and see if it supports this chip..post both chips..

                              I need Vbios for lenovo y540, rtx 2060 mobile, gives b32 till b64 errors on B1, nvmt wont read vbios.. replaced b1 yet no change.. main bios is flashed by someone else.. so not sure if that may have caused the issue. Laptop works but code43 on rtx2060..
