Hi shyiab.
Many many thanks for your efforts and i truly appreciate your help. The BIOS "kind of works" as it seems... It did boot up (it shows INVALID in PRODUCT NAME, MTM and SN, but i do not care too much now), i am able to enter the BIOS, it detects the HDD and everything seems to work as normal until i am trying to reinstall Windows via USB. I doesn't detect HDD to install to... I guess it has nothing to do with the BIOS but rather with the drivers for M2 NVME..
Anyway, i'm still looking for a solution, but the BIOS issue seems to be solved (at least for one of the laptops...

Hi, please find the ones extracted initially, for backup... Unfortunately, i don't remember which is which, i've save them as 1 and 2 without serial number....
