Chameleon 2 Rc3 Installer

  • I’m trying to install Chameleon on my boot flash-drive, but the installer says, that this bootloader could be installed only at drives with Mac OSX. Also, i tried to install Chameleon 2.1, all is okay, but i’m installing Yosemite, so i need this version.
  • Chameleon is a Darwin/XNU boot loader based on Apple's boot-132. Because Chameleon now uses part of GPL V2 licensed code in 2 files, it.must. conform to the most restrictive license that it uses that is the: GPL Version 2 LICENSE Chameleon can thus be (and has to be) freely distributed under the term of the GPL V2 license which prevails, as it is the most restrictive license.

This package will install Chameleon 2 RC4 r684 to your OS X partition. It provides full Snow Leopard support. It loads 64-bit kernel and extensions by default. Osx86 install: Chameleon 2.0 install guide Chameleon: Chameleon 2.0-RC4 is out! Chameleon: Bring Mac OS X Developers Together.

About Chameleon and Lion

PCEFI 10.6 can be compiled just fine with new boot.h from Lion’s SDK, it allows it to boot lion’s kernel just fine, pass kexts to it and etc, but then kernel has double fault, in one of its many threads, so its very hard to track down.

Here is the sorry, wrong file, will uplaod proper one in a few if you want, but keep in mind, it DOES NOT WORK with snow leopard.

Not sharing sources because its same as 10.6.

Now about possible reasons for panic, it’s:

  • Not new format of passing kext/mkext to kernel, I compiled snow leopard kernel with new boot.h (so new boot_args, everything else is old), new boot.efi can boot it just fine, as well as booter I posted before.
  • Not new devicetree format, same reason as above.

There is actualy not much reason which can cause double fault, so feel free to investigate 😛

Thanks to cparm for idea about kernelcache, here is booter for lion which will use kernelcache if u specify option -usecache

They way you will be able to boot Lion, but double fault seems to happen sometimes still (like if you use Wait=y argument, it will DF)

Binary and Sources (fixed kernelcache/prelink detection)

No /Extra mkext/kexts if kernelcache used. and this booter doesnt work with snowleopard

If getting DF – try to boot Snow with old chameleon, then reboot and boot lion with new, sometimes helps

device-properties doesn’t seem to work.

I can't say enough great things about the Chameleon bootloader. One thing that I had some trouble finding at first was any documentation to accompany it. A lot of valuable information is supplied in the Doc folder if you download the source code of Chameleon RC3. Mostly it tells users how to set boot flags and advanced startup options to enable different functionality.
You can use these options from the Chameleon bootloader itself when starting up your machine. Stop the Chameleon countdown and type the command at the boot prompt. If you want any of the options to be selected by default, you must enter them into your com.apple.boot.plist- in your /Extra folder. Simply drag this file to the desktop, open and edit in TextEdit, then drag back to /Extra.
The following text is taken from the Chameleon documentation provided in the source folder available on http://chameleon.osx86.hu/ I edited and clarified where necessary.

The boot: prompt waits for you to type advanced startup options. If you don't type anything, the computer continues starting up normally. It uses the kernel and configuration files on the startup device, which it also uses as the root device.Chameleon
Chameleon 2 rc3 installer manualAdvanced startup options use the following syntax:
[device] [arguments]
Example arguments include:
device: rd= (e.g. rd=disk0s2)
device: rd=* (e.g. rd=*/PCI0@0/CHN0@0/@0:1)
kernel: kernel name (e.g. 'mach_kernel' - must be in '/' )
flags:
-v (verbose)
-s (single user mode)
-x (safe mode)
-F (ignore boot configuration file)
'Graphics Mode'='WIDTHxHEIGHTxDEPTH'
(e.g. '1024x768x32')
kernel flags
(e.g. debug=0x144)
io=0xffffffff
(defined in IOKit/IOKitDebug.h)
Example:
mach_kernel rd=disk0s1 -v 'Graphics Mode'='1920x1200x32'
If the computer won't start up properly, you may be able to start it up using safe mode. Type -x to start up in safe mode, which ignores all cached driver files.

F5
Rescans optical drive.
F10
