73 | Change: added -legacy kernel flag. This flag tells the booter to load i386 arch before is passed to␊ |
74 | ␉␉the kernel. This procedure only needs to be done on Snow Leopard. -legacy tells the kernel␊ |

84 | Note: just out of curiosity and for those who don't know, Legacy Mode is in fact the mode used␊ |
85 | ␉␉by 32 bit "only" processors! Since OS X kernel can handle 64 bit apps even on i386 arch,␊ |

94 | - (rev 335)␊ |

103 | Change: removed 3 keys to handle PCI Root UID, two of them executing the exact same code␊ |

116 | Changes: file loading related changes (search algo). The short story:␊ |
117 | ␊ |
118 | ␉␉Change: added a key to disable "override" Boot.plist from overriding the values on the "default"␊ |
119 | ␉␉␉␉Boot.plist. Only the values overriding is disabled, not the file loading.␊ |

123 | ␉␉ Note: as far as i know, loading a override Boot.plist is not mandatory!␊ |
124 | ␉␉␉␉Please correct me if i'm wrong.␊ |
125 | ␉␉␊ |
126 | ␉␉Motif: just in case ;)␊ |
127 | ␉␉␉␉I was totally unaware of this Boot.plist override for a long time; this messed with my mind␊ |
128 | ␉␉␉␉a lot of times! too many. So the first thing i did to the booter when i had the chance,␊ |
129 | ␉␉␉␉was make sure i had this under control.␊ |
130 | ␉␉␉␉The problem:␊ |
131 | ␉␉␉␉- first path checked: rd(0,0)/Extra/com.apple.Boot.plist␊ |
132 | ␉␉␉␉ nice, override Boot.plist can be loaded from a ramdisk.␊ |
133 | ␉␉␉␉- second path: /Extra/com.apple.Boot.plist (the plist on Selected volume)␊ |
134 | ␉␉␉␉ great, if we have the booter installed on a usb stick, that by the way it's the␊ |
135 | ␉␉␉␉ main device used these days to hold a rescue booter, the Boot.plist on it will be␊ |
136 | ␉␉␉␉ ignored (unlike one on a ramdisk) and the one on Selected volume loaded.␊ |
137 | ␉␉␉␉- and there's no way to override it (config=<file> is not working).␊ |
138 | ␉␉␉␉This can cause all sorts of anxiety and panic attacks, if you are unaware of this␊ |
139 | ␉␉␉␉like many people are.␊ |
140 | ␉␉␊ |

148 | ␉␉␉␉␊ |

153 | ␉␉␊ |
154 | ␉␉ Note: there's a typo on the comment of rev 337 commit;␊ |
155 | ␉␉␉␉Extensions=/path-to-folder/ should be read like kext=/path-to-folder/.␊ |
156 | ␉␉␊ |

158 | ␉␉␊ |
159 | ␉␉␉␉---------------//---------------//---------------␊ |
160 | ␊ |
161 | ␉␉Change: added a "new" search algo, to load Extra extensions.␊ |
162 | ␉␉␉␉Pros:␊ |
163 | ␉␉␉␉- hands-off search of all main files. If you don't want a certain file to be loaded,␊ |
164 | ␉␉␉␉ just don't place it on a default searched path (as usual) or override it with key.␊ |
165 | ␉␉␉␉ First file found, is the one loaded.␊ |
166 | ␉␉␉␉ Check FileLoad.txt for info on searched paths.␊ |
167 | ␉␉␉␉- easy to configure with other paths.␊ |
168 | ␉␉␉␉- easy add to another file load functions.␊ |
169 | ␉␉␉␉- no ambiguous paths!! It's bt(0,0) or nothing! (yeah, i'll explain this else were).␊ |
170 | ␉␉␉␉- consistency across all file loading.␊ |
171 | ␉␉␉␉␊ |
172 | ␉␉␉␉Cons:␊ |
173 | ␉␉␉␉- none that i could test, so far. The only booter install configuration that i can't␊ |
174 | ␉␉␉␉ really test is RAID.␊ |
175 | ␉␉␊ |
176 | ␉␉Motif: after adding the kext= key, i still couldn't override the Extra extensions loaded from␊ |
177 | ␉␉␉␉the Selected volume, in case they were messed up and i needed to load another set from␊ |
178 | ␉␉␉␉else were. It happens that similarly as with override Boot.plist, /Extra/Extensions␊ |
179 | ␉␉␉␉(or /Extra/Extensions.mkext) is the first path to be checked on a HDD and worse,␊ |
180 | ␉␉␉␉there's no argument to limit the action; this path is ALWAYS checked and if files are␊ |
181 | ␉␉␉␉found they are loaded and will override any other files loaded from another path, like a␊ |
182 | ␉␉␉␉ramdisk (only path checked before /Extra/Extensions), making a recovery much more␊ |
183 | ␉␉␉␉complicated (not impossible).␊ |
184 | ␉␉␉␉So, according to at least one of my guidelines (simplify booter use as much as possible),␊ |
185 | ␉␉␉␉changes to the code are/were needed.␊ |
186 | ␉␉␉␉This algo was initially a merge between the search algo found on search_and_get_acpi_fd()␊ |
187 | ␉␉␉␉(acpi_patcher.c), to load ACPI table and the one on LoadDrivers() (driver.c); also, the␊ |
188 | ␉␉␉␉/Extra/* path was still included. I tried a long time playing with the used arguments␊ |
189 | ␉␉␉␉(and others) to keep this path, as all i wanted was to give another priority to the file␊ |
190 | ␉␉␉␉loading, but there was always problems; a file that kept defaulting to the Booter volume␊ |
191 | ␉␉␉␉when i was trying to load it from Selected volume or the other way around.␊ |
192 | ␉␉␉␉So, as i always wanted to try taking advantage of Chameleon's ability to load files␊ |
193 | ␉␉␉␉from specific OS folders (e.g. /Extra/10.5), i gave it a try and here is the outcome.␊ |
194 | ␉␉␉␉␊ |
195 | ␉␉ Note: it doesn't make any sense taking advantage of this specific OS folders and still check␊ |
196 | ␉␉␉␉the Selected volume. Thus except for the obvious files like kernel, SystemVersion.plist,␊ |
197 | ␉␉␉␉system caches, etc..., no other file is loaded from Selected volume (paths started with / ).␊ |
198 | ␉␉␉␉To put it simple, as an example, when installed to a usb stick, this booter will not search␊ |
199 | ␉␉␉␉for any files on the Extra folder of the volume were the system is installed!␊ |
200 | ␉␉␉␉Or in other words, the booter will only check the Extra folder on the booter volume␊ |
201 | ␉␉␉␉(paths started with bt(0,0) ), the usb stick in this example.␊ |
202 | ␉␉␉␉Anyway, /Extra paths can still be passed with the use of override keys!␊ |
203 | ␊ |
204 | ␉␉␉␉---------------//---------------//---------------␊ |
205 | ␉␉␊ |
206 | ␉␉Change: expanded this "new" search algo to dsdt.aml and smbios.plist.␊ |
207 | ␉␉␊ |
208 | ␉␉ Note: same override keys used.␊ |
209 | ␉␉␊ |
210 | ␉␉Motif: check Guidelines.␊ |
211 | ␊ |
212 | ␉␉␉␉---------------//---------------//---------------␊ |
213 | ␊ |
214 | ␉␉Change: tweaked the loading of override Boot.plist (loadOverrideConfig(), stringTable.c) according␊ |
215 | ␉␉␉␉the new search algo guideline: everything loads from Booter volume.␊ |
216 | ␉␉␉␉The search for this file was also extended to specific OS folders, to "emulate" the search␊ |
217 | ␉␉␉␉on Selected volume. Also added a verbose message to signal when user doesn't provide a␊ |
218 | ␉␉␉␉override plist.␊ |
219 | ␊ |
220 | ␉␉ Note: again, as far as i know, loading a override Boot.plist is not mandatory!␊ |
221 | ␊ |
222 | ␉␉Motif: payback for all the neurons i burned while i was not aware of override Boot.plist function!!␊ |
