| Source at commit 335 created 13 years 9 months ago. By azimutz, Ok, this were the fun stops :) - two keys to do the same thing, two keys to remember... thought it was a good idea to merge the best of the two, the educational side of arch=i386 + the practical one of -x32. And while i'm at it, why not make it even more practical!? Typing just 32 to get i386 arch. - -legacy kernel flag was not being passed on 10.6.x; the reason why is on the kernel code, Legacy mode is only available when i386 arch is specified (makes sense). So, while testing Meklort's kernel patcher, i felt the need to add the key. -legacy flag, sets i386 arch on the booter side & Legacy mode on the kernel side. - and how do we override the last two if they are flagged on Boot.plist? Typing just 64 to get x86_64 arch. - changed the code so x86_64 arch becomes default, seems more natural. And also added these flags to BootHelp.txt | |

| 2 | Chameleon Boot Loader␊ |
| 3 | =====================␊ |
| 4 | ␊ |
| 5 | What is it?␊ |
| 6 | -----------␊ |
| 7 | ␊ |
| 8 | Chameleon is combination of various boot loader components. It is based␊ |
| 9 | on David Elliott's fake EFI implementation added to Apple's boot-132␊ |
| 10 | project. Chameleon is extended with the following key features:␊ |
| 11 | ␊ |
| 12 | ␊ |
| 13 | Features␊ |
| 14 | --------␊ |
| 15 | ␊ |
| 16 | - Device Property Injection via device-properties string in com.apple.Boot.plist␊ |
| 17 | - hybrid boot0+boot1h loaders for both MBR and GPT partitioned disks.␊ |
| 18 | - automatic FSB detection code even for recent AMD CPUs.␊ |
| 19 | - Apple Software RAID support.␊ |
| 20 | - stage2 loader (boot) can be placed as a regular file in the boot␊ |
| 21 | partition's root folder. It has precedence over the embedded␊ |
| 22 | startupfile.␊ |
| 23 | ␊ |
| 24 | ␊ |
| 25 | Installation␊ |
| 26 | ============␊ |
| 27 | ␊ |
| 28 | Normal Install (non-RAID):␊ |
| 29 | --------------------------␊ |
| 30 | ␊ |
| 31 | Suppose that your installation is on /dev/disk0s2␊ |
| 32 | ␊ |
| 33 | - Install boot0 to the MBR:␊ |
| 34 | ␉␉sudo fdisk -f boot0 -u -y /dev/rdisk0␊ |
| 35 | ␊ |
| 36 | - Install boot1h to the partition's bootsector:␊ |
| 37 | ␉␉sudo dd if=boot1h of=/dev/rdisk0s2␊ |
| 38 | ␊ |
| 39 | - Install boot to the partition's root directory:␊ |
| 40 | ␉␉sudo cp boot /␊ |
| 41 | ␊ |
| 42 | No need to use startupfiletool anymore!␊ |
| 43 | ␊ |
| 44 | ␊ |
| 45 | RAID Install:␊ |
| 46 | -------------␊ |
| 47 | ␊ |
| 48 | Suppose that your installation is on /dev/disk3, which is either a mirror- or a␊ |
| 49 | stripeset consisting of /dev/disk0 and /dev/disk1␊ |
| 50 | ␊ |
| 51 | Mac OS X creates a small helper partition at the end of each RAID member disk,␊ |
| 52 | namely /dev/disk0s3 and /dev/disk1s3␊ |
| 53 | ␊ |
| 54 | - Install boot0 to the MBR of both disks:␊ |
| 55 | ␉␉sudo fdisk -f boot0 -u -y /dev/rdisk0␊ |
| 56 | ␉␉sudo fdisk -f boot0 -u -y /dev/rdisk1␊ |
| 57 | ␊ |
| 58 | - Install boot1h to the bootsector of each boot partition:␊ |
| 59 | ␉␉sudo dd if=boot1h of=/dev/rdisk0s3␊ |
| 60 | ␉␉sudo dd if=boot1h of=/dev/rdisk1s3␊ |
| 61 | ␊ |
| 62 | - Install boot to both helper partition's root directories.␊ |
| 63 | ␉␉diskutil mount disk0s3␊ |
| 64 | ␉␉cp boot /Volumes/Boot\ OSX␊ |
| 65 | ␉␉diskutil unmount disk0s3␊ |
| 66 | ␉␉diskutil mount disk1s3␊ |
| 67 | ␉␉cp boot /Volumes/Boot\ OSX␊ |
| 68 | ␉␉diskutil unmount disk1s3␊ |
| 69 | ␊ |
| 70 | - Add "rd=uuid boot-uuid=506D8F03-0596-32D8-BE0B-E3A4E7D5C72A" to your kernel flags␊ |
| 71 | (replace with your root volume's UUID; find out using "Disk Utility.app", right␊ |
| 72 | ␉ click on your root volume, then Get Info"):␊ |
| 73 | ␉␉nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist␊ |
| 74 | ␉␉touch /System/Library/Extensions␊ |
