Re: a1312 e2429 bios dump

Hello,

Thx for your post but how to modify the serial number? Or is it not necessary?

And what about RAM configuration?

For 2017 and older machines, serial number is stored in Fsys store of BIOS and can be edited with hexadecimal editor. Fsys checksum needs to be fixed afterwards
Search for "ssn", edit the serial number, save, open dump in UEFITool, go to the Fsys store and write down the suggested checksum in the panel on the right. Checksum is 4 bytes at the end of the Fsys store, between one zone of 0x00 either Gaid or another zone of 0xFF, it must be written in reverse order (so last 2 characters from UEFITool must be written first).
