A free book teaching the foundations needed to write an operating system from scratch on x86_64.
Why you might care
Aimed at self-learners who want to build an OS by reading hardware datasheets rather than following step-by-step tutorials. Covers x86 assembly, ELF, linking, and debugging on bare metal with gdb and QEMU, using pure C with no standard library. Parts 1 and 2 are said to give enough grounding to continue on the OSDev wiki or Linux kernel books.
