Trying to fix a BIOS corruption issue on a Lenovo Legion Pro 7 16IRX8. The motherboard model number is 5B21L45527. First of all, can folks confirm which chips need to be dumped? Images of the top and bottom of the board are attached.

post merged...next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread..

Lenovo Legion 7 Pro 16IRX8.
MTM: 82WR0000US
S/N: PF48QSDX
1st BIOS chip: XMC 25RH64CHIO (used XM25RH64C in Neoprogrammer), second chip XMC 25QH128IO (detected as XM25QH128C in Neoprogrammer)
Chips have been dumped with CH341a (w/ 3v mod) using Neoprogrammer with chips soldered directly to CH341a. A test clip was not used. But I believe the person who looked at it initially did try to program it using a test clip so it's quite possible the chips could already corrupted.

Thanks! I tried flashing these. System posts on but does not post. Fans run, keyboard backlight comes on, screen stays dark, no response from keyboard. After around 3 minutes there's a loud beep and it turns off, then it powers back on in around 10 seconds and this process repeats. Tried letting it sit 20+ min in case it was still going through BIOS reset process but no change. Thoughts?

Check hardware.

Seems like it may be encountering a problem during memory training? I've obtained a copy of the original bios dumps that were made by the owner who was using a test clip to read the chips. There does appear to be corruption in the me region on these dumps.
