# Installation

You need BeOS/PowerPC R4. R3 or earlier versions will not work.

1. Unpack the SheepShaver package (if you are reading this, you probably have already done this)
2. On a BeBox, you need a copy of a PCI PowerMac ROM (4MB) in a file called "ROM" in the same folder SheepShaver is in (but you can select a different location in the settings window). SheepShaver can also use the "Mac OS ROM" file that comes with MacOS 8.5/8.6 (look in the System Folder on your MacOS CD). In order to legally use SheepShaver, you have to own the ROM the image file was taken from.
