| 2 | ␊ |
| 3 | Installation:␊ |
| 4 | ␊ |
| 5 | - get the source, compile; find modules at /sym/i386, with .dylib file extension.␊ |
| 6 | ␊ |
| 7 | - create an /Extra/modules folder on the volume from were the booter is going to load from,␊ |
| 8 | ␉copy Symbols.dylib (mandatory) to modules folder, plus any other module you wish to load.␊ |
| 9 | ␊ |
| 10 | - update boot file or reinstall the booter completely, as needed.␉␊ |
| 11 | ␊ |
| 12 | Note: GraphicsEnabler, MemDetect & ForceHPET patches are now converted to modules.␊ |
| 13 | ␊ |
| 14 | ␊ |
| 15 | How to use?␊ |
| 16 | ␊ |
| 17 | - Just check if a key is needed to activate the functionality you pretend to use. Otherwise␊ |
| 18 | ␉all modules are loaded at startup from the default location, before the boot prompt.␊ |

| 22 | What are modules?␊ |
| 23 | ␊ |
| 24 | - Modules can be refered as "plugins", adding and/or replacing booter functionality, without␊ |
| 25 | ␉touching the "core" of the booter. If you are familiar with e.g. browser plugins␊ |
| 26 | ␉(like Firefox's Addons), you know what i'm talking about; they either add completely new␊ |
| 27 | ␉functionality or replace/modify existing one; same thing with modules and Chameleon.␊ |

| 34 | Featured modules:␊ |
| 35 | ␊ |
| 36 | - Symbols.dylib: first one to load, contains all the symbols found on the booter.␊ |

| 60 | ␉Let's just say that the only patch needed by the 925 on Legacy Mode(**) is cpuid_set!␊ |
