May be some useful information. To add support for a new processor, usually do not need to update the CPU microcode. The CPU microcode is useful only to fix bugs that may be present in the internal code of the CPU. I compared two versions of AMI BIOS: in the second was added only the support for a CPU with higher frequency. Pulling out all the modules of the two bios and comparing them with an hex editor, I found that:
- both bios do not contain cpu microcode;
- between modules I found difference only in SMBIOS (that contains the header of the bios) and in Single Link Arch. So, normally, in SIngle Link Arch Module is added support for a new cpu. . I then tried to extract dsdt and to compare the two, but I'm not able to understand the differences to understand the operation ....
