# 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 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
