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!

The Dell Latitude CPi A366XT is an older laptop with 440BX chipset. We're currently evaluating if it's possible to write coreboot support for it.

Hardware

Overview:

Northbridge: Intel 440BX
Southbridge: Intel 82371EB
Super I/O: SMSC FDC37N958FR
- The Super I/O also "contains" the embedded controller (EC), which is an 8051 derivate.
Audio/video controller: Neomagic NM2200 MagicGraph/MagicMedia 256AV
PCMCIA controller: Texas Instruments PCI1225
ROM/BIOS chip: AM29F040B (PLCC, 512 KB, parallel protocol, socketed)
- Unfortunately you can not hot-swap a chip in this laptop, it'll immediately do a hard poweroff if you try it (the EC firmware, which is part of the flash chip, likely doesn't like you removing the chip).
