| 1 | The possible info at the moment:␊ |
| 2 | ␊ |
| 3 | Installation:␊ |
| 4 | ␊ |
| 5 | - get the source, compile; find modules at /sym/i386, with .dylib file extension.␊ |
| 6 | ␊ |
| 7 | - create a /Extra/modules folder, copy Symbols.dylib (mandatory) to modules folder,␊ |
| 8 | ␉plus any other module you wish to load.␊ |
| 9 | ␊ |
| 10 | Note: GraphicsEnabler & MemDetect are now converted to modules.***␊ |
| 11 | ␊ |
| 12 | - update boot file or reinstall the booter completely, as needed.␊ |
| 13 | ␊ |
| 14 | ␊ |
| 15 | How to use?␊ |
| 16 | ␊ |
| 17 | - Just check if a key is needed to activate the module you pretend to use. Otherwise␊ |
| 18 | ␉modules are loaded at startup by the booter from default location. (check Issues below).␊ |

| 22 | What are modules?␊ |
| 23 | ␊ |
| 24 | - good question! Well, can't add much on the "geek" side... need to study the stuff so␊ |
| 25 | ␉i don't start dumping bs. The easy answer is they are like plugins, adding/replacing␊ |
| 26 | ␉booter functionality. For instance: the Kernel Patcher (Kpatcher) is around for some time,␊ |
| 27 | ␉integrated on boot file like any other Chameleon function; with Modules support Kpatcher␊ |
| 28 | ␉can now live as a module, freeing the space occupied on boot file␊ |
| 29 | ␉(one of module's advantages).␊ |
| 30 | ␉␊ |
| 31 | ␉␊ |
| 32 | Featured modules:␊ |
| 33 | ␊ |
| 34 | - Symbols.dylib: always needed to load other modules! It's the first one to load and no␊ |
| 35 | ␉other module will work if this one fails. The booter will still perform as usual,␊ |
| 36 | ␉if it fails to load. ␊ |

| 51 | ␉Note on functionality: as it is, Kpatcher allows my Pentium D 925 to load vanilla(*)␊ |
| 52 | ␉kernel, with the help of -legacy flag; to enter x86_64 world i still need to patch␊ |
| 53 | ␉the kernel sources, as the 925 has no Supplemental SSE3 instructions and there's␊ |
| 54 | ␉no patch to fix this on Kpatcher atm (don't even know if is possible?!).␊ |
| 55 | ␉I assume that, the great majority of the legacy/unsupported processors with at least␊ |
| 56 | ␉SSE3 instructions, will benefit of the same treatment!␊ |
| 57 | ␉Let's just say that the only patch needed by the 925 on Legacy Mode(**) is cpuid_set!␊ |
| 58 | ␉␊ |
| 59 | ␉Note: Kernel Patcher can stop working due to changes on the kernel code.␊ |
| 60 | ␊ |
| 61 | - GraphicsEnabler: graphics enabler option converted to module.␊ |
| 62 | ␊ |
| 63 | ␉- same activation key used.␊ |

| 66 | ␊ |
| 67 | ␉- same deactivation key used. (enabled by default)␊ |
| 68 | ␉␊ |
| 69 | - HelloWorld.dylib: just a notifier (not mandatory).␊ |
| 70 | ␊ |
| 71 | ␊ |
| 72 | (*) In this context, "vanilla" means the use of a non pre-patched kernel; what we do here is␊ |
| 73 | ␉patch the kernel on the fly, in memory.␊ |

| 79 | Issues:␊ |
| 80 | ␊ |
| 81 | - the default path for loading modules (/Extra/modules/) is not being respected, the booter␊ |
| 82 | ␉always checks bt(0,0)/Extra/modules/ instead.␊ |
| 83 | ␉Anyway, i already intended to change the path due to the concept of this booter␊ |
| 84 | ␉and so i did it. Of course the problem is still there and needs to be fixed, at least if␊ |
| 85 | ␉one wants to be able to load modules from selected volume.␊ |
| 86 | ␊ |
| 87 | - compiling modules under Leo (XCode 3.1.4) is not possible at the moment.␊ |
