!!! Danger
The BIOS mod may permanently break TPM. Consider this if you wish to proceed.
The BIOS mod may permanently break TPM. Consider this if you wish to proceed, especially now that TPM is required for Windows 11.
A modded BIOS will allow for more optimizations to be made for macOS and will overall make your hackintosh better. I am a BIOS modding novice myself, but with these instructions, I was able to mod my x1c6 BIOS in less than one hour. I fully recommend doing this for all who think themselves capable. Furthermore, the default `config.plist` for this repository is meant to accommodate a modded BIOS with appropriate settings. If you cannot mod your BIOS or is unwilling to do so, use `Vanilla BIOS.plist`.

The CH341a SPI Programmer and SOIC8 Clip are needed to dump, mod, and flash the BIOS chip. There are better and more profession alternative devices but I've found this one to be adequate for the job.

4. Remember to **dump the vanilla twice and use `diff` to make sure things were dumped properly**, store this backup somewhere safe.
5. Confirmed working `BIOS-v1.45`, I cannot be sure about other BIOS versions. Though they will most likely work as well.
6. The modded BIOS does not need to be signed by `thinkpad-eufi-sign`. Just **remember to replace 4C 4E 56 42 42 53 45 43 FB with 4C 4E 56 42 42 53 45 43 FF on the patched BIOS.**
