SLOF

Slimline Open Firmware (SLOF) is initialization and boot source code based on the IEEE-1275 (Open Firmware) standard, developed by engineers of the IBM Corporation.

The SLOF source code provides illustrates what’s needed to initialize and boot Linux or a hypervisor on the industry Open Firmware boot standard.

Currently the SLOF source code is hosted on github at https://github.com/aik/SLOF/ and provides:

• Documentation

• An Open Firmware implementation for prototyping, test, and debug

• Low Level Firmware for IBM’s JS20, JS21 and the YDL PowerStation (partially closed source)

• Firmware for the emulated ‘pseries’ machine of QEMU
