Datasheets
The wiki is being retired!
Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!
This page lists publically available datasheets and programming guides from various vendors. It includes CPU, chipset, Super I/O, and many other datasheets.
x86 architecture
AMD
AMD provides their AMD64 Architecture and Software manuals, which are a very useful reference for AMD systems, of course (but also explain lots of non-AMD-specific x86 stuff too):
- Volume 1: Application Programming
- Volume 2: System Programming 24593
- Volume 3: General-Purpose and System Instructions
- Volume 4: 128-Bit Media Instructions
- Volume 5: 64-Bit Media and x87 Floating-Point Instructions
- Volume 6: 128-Bit and 256-Bit XOP and FMA4 Instructions
Other AMD documents:
- Lightweight Profiling Specification
- AMD I/O Virtualization Technology (IOMMU) Specification
- Open Platform Management Architecture Specification
- CPUID Specification
- Advanced Platform Management Link (APML) Specification
Intel
Intel provides their Intel® 64 and IA-32 Architectures Software Developer's Manuals which are a very useful reference to the x86 architecture in general:
- Volume 1: Basic Architecture
- Volume 2A: Instruction Set Reference, A-M
- Volume 2B: Instruction Set Reference, N-Z
- Volume 3A: System Programming Guide
- Volume 3B: System Programming Guide

There are many datasheet archives on the web which may have other (usually older) datasheets which already disappeared from vendor websites.
