# Open Firmware for OF816
|
||||
|
||||
This directory contains Forth source implementing Open Firmware on top of
|
||||
OF816. It is based on IBM's [Slimline Open Firmware](https://github.com/aik/SLOF)
|
||||
that is notably used in IBM POWER systems and QEMU.
|
||||
|
||||
**There are Bugs**
|
||||
|
||||
The build script borrows tricks from SLOF to incorporate the C preprocessor
|
||||
and remove comments and extra lines from the code, producing a single file
|
||||
that can be used with EVALUATE.
|
||||
|
||||
SLOF is licensed under a BSD license, and since the files in this directory
|
||||
are a derivative work, the license is reproduced in this directory as
|
||||
SLOF-LICENSE.
