Could anyone explain how the firmware (implementing UEFI, I assume) interacts with the components described here? My knowledge is limited to Tianocore edk2 on amd64 platforms.
- monocasa 5y agoThere isn't UEFI or anything like it. iBoot takes that place.
- microtonal 5y agoThere is no UEFI, only a simple boot ROM and the first stage of iBoot is in NOR flash. The rest is all on NVMe. There is a detailed description here: https://github.com/AsahiLinux/docs/wiki/M1-vs.-PC-Boot https://github.com/AsahiLinux/docs/wiki/M1-vs.-PC-Boot
