Hi everyone,
I am reporting success, the motherboard is functional. But I had problems with desoldering with hot air. At 380 degrees Celsius I left it because I was afraid of destroying the chip. Probably a very hard soldering wave. I used the classic method with soft tin and a suction copper wick. After soldering, nothing worked. Again, the copper wick helped, which removed microscopic bridges. So for the M92P model 3218 AL7 motherboard IS7XM ver. 1.0 the above-mentioned BIOS is functional. Thank you all again for your help.

recep1982 thanks for the advice. I have already downloaded your files from 27.12.2024. They seem to be the same as those from SMDFlea from 19.3.2019. I will compare them in the programmer and try them. Then I will let you know how it turned out. Thank you all for the advice.

I understood that I should overwrite U4(MX25L6406E) and U5(MX25L1606E). But I need the correct BIN file for each model 3218 AL7. Can someone please provide me with these files? Thanks in advance

Hi, I have a motherboard from ThinkCentre M92P IS7XM ver.1.0 Model: 3218 AL7. Original BIOS: 9SKT80AUS revision: 9S80A Date: 24.04.2014. When flashing in Windows to a new BIOS downloaded from the LENOVO website according to the serial number, the upgrade crashed. I can get into the BIOS, but booting does not work. I do not know which chip the BIOS is loaded on. Which one should I unsolder. There are two. U4: MX25L6406E and U5: MX25L1606E. I would also need a correct new BIOS. I have a programmer. I did the upgrade because of the CPU, which the older BIOS could not handle. Thank you very much for...

Hi, I came to this forum because my BIOS crashed during an upgrade and I need help.
