Ex)

❶ "config=gfx"

- it load a config file with different gfx string, so it loads /Library/Preferences/SystemConfiguration/gfx.plist instead of com.apple.Boot.plist

❷ rd=disk0s3 -s -x "Graphics Mode"="800x600x32" platform=X86PC

- it can combine the flags:

❸ "rd=boot-uuid, boot-uuid = XXXXX" or "boot-uuid - XXXXX"

- Define Hard Disk

❹ "busratio=20"

- yea, it used i7 cpu in 10.5.6. after upgrading to 10.5.7, it does not need.

❺ "acpi_level=2 acpi_layer=0x80"

- Not sure, it will work.

First of all, Thanks roisoft and Evosx86 team,

1. download in ✒here.

    download pkg ✒here.  

2. Some guide as followings.

About the new options

SMBIOS
Finally you can specify your smbios.plist location using a device selector prefix like “SMBIOS=rd(0,0)/Extra/smbios.plist”.

VideoROM
You can pass an alternate video ROM image file to the system.

VBIOS
Using this boolean switch, you can control the injection of your video BIOS to device-properties. We got various reports if this switch is really needed to make your graphics device handled correctly by the system.

You can use the same booter partition for both Leopard and the recent Snow Leopard; to do that you can put your OS version specific KEXTs/MKEXT this way:
/Extra/10.(5|6)/Extensions[.mkext]

3.So I make a following folder for switching Windows, Snow and Leopard OSX even Linux.

* 다음 그림과 같이 폴더를 만들어주면 부트로더 하나로 Leopard와 Snow Leopard를  멀티부팅할수 있다.

4. Boot Helper

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.

Advanced startup options use the following syntax:

   [device]<kernel> [arguments]

Example arguments include

device: rd=<BSD device name> (e.g. rd=disk0s2)

   rd=*<IODeviceTree path> (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.

Special booter hotkeys:

F5 Rescans optical drive.

F10 Scans and displays all BIOS accessible drives.

Special booter commands:

?memory Displays information about the computer's memory.

?video Displays VESA video modes supported by the computer's BIOS.

?norescan Leaves optical drive rescan mode.

Additional useful command-line options:

config=<file> Use an alternate Boot.plist file.

Options useful in the com.apple.Boot.plist file:

Wait=Yes|No Prompt for a key press before starting the kernel.

"Quiet Boot"=Yes|No Use quiet boot mode (no messages or prompt).

Timeout=8 Number of seconds to pause at the boot: prompt.

"Instant Menu"=Yes Force displaying the partition selection menu.

   =hd(x,y) where 'x' is the disk number, 'y' the partition number.

GUI=No Disable the GUI (enabled by default).

"Boot Banner"=Yes|No Show boot banner in GUI mode (enabled by default).

"Legacy Logo"=Yes|No Use the legacy grey apple logo (disabled by default).

GraphicsEnabler=Yes|No Automatic device-properties generation for graphics cards.

VideoROM=<file> Use an alternate ROM image (default path: /NVIDIA.ROM).

VBIOS=Yes|No Inject VBIOS to device-properties.

EthernetBuiltIn=Yes|No Automatic "built-in"=yes device-properties generation

   for ethernet interfaces.

USBBusFix=Yes Enable the EHCI and UHCI fixes (disabled by default).

EHCIacquire=Yes Enable the EHCI fix (disabled by default).

UHCIreset=Yes Enable the UHCI fix (disabled by default).

Wake=No Disable wake up after hibernation (enbaled by default).

ForceWake=Yes Force using the sleepimage (disabled by default).

WakeImage=<file> Use an alternate sleepimage file

   (default path is /private/var/vm/sleepimage).

DropSSDT=Yes Skip the SSDT tables while relocating the ACPI tables.

DSDT=<file> Use an alternate DSDT.aml file

   (default path: /DSDT.aml /Extra/DSDT.aml)

SMBIOS=<file> Use an alternate smbios.plist file

   (default path: /smbios.plist /Extra/smbios.plist

   bt(0,0)/Extra/smbios.plist).

SMBIOSdefaults=No Don't use the Default values for SMBIOS overriding

   if smbios.plist doesn't exist, factory

   values are kept.

"Scan Single Drive" Scan the drive only where the booter got loaded from.

   =Yes|No Fix rescan issues when using a DVD reader in AHCI mode.

Rescan=Yes Enable CD-ROM rescan mode.

"Rescan Prompt"=Yes Prompts for enable CD-ROM rescan mode.

3. Installation

Open the Terminal and command as Followings

$ sudo dd if=boot1h of=/dev/rdisk0s2

$ sudo cp boot /

$ sudo cp -Rf i386 /usr/standalone/

If you used MBR Partition, you need install boot0 to the MBR, additionally:

$ sudo fdisk -f boot0 -u -y /dev/rdisk0

Followings is com.apple.Boot.plist:

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

* EFI Partition still don't support, probably people who are using "efi" partition love terminal.

2. BootCDMaker

First of all, Thanks Trauma for guide.

BootCDMaker is simple utility to rapidly create Chameleon BootCD. This application use a mix of bash & osascript (AppleScript).

Using BootCDMaker is really easy and simple:

2-1. Grab your Mkext / smbios.plist / DSDT.aml / mach_kernel and drop them in "BootCD Contents" folder. (be sure to respect standard file syntax)
2-2. If you don't add you com.apple.boot.plist to "Extra Contents" it will be generated automatically.
2-3. BootCDMaker features :

- Automatic NVIDIA graphics injection
- Ethernet built-in injection
- EHCIacquire (USB2) fix
- UHCIreset (USB1.1) fix
- Skip the SSDT tables while relocating the DSDT table
- Use the legacy grey apple logo
- Custom kernel flags edition
- Custom device-properties edition
- Legacy mode : this will create an old fashioned boot cd, known as BOOT-132 CD, but powered by the latest release of chameleon. This should fix BIOS incompatibility with chameleon built in Eltorito loader.
- Mkext creation utility
- ISO Burning utility

2-6. BootCDMaker will automatically backup the previous BootCD.iso build to the "Desktop/BootCDMaker-Out/Previous-BootCD" folder.

What mode should you use :

Default : if you have a recent computer you should try this.
Legacy : if Default is not loading (hang at boot) try this.

Version history :

- "0.7" include the latest build of chameleon's cdboot (r658)

- "0.8" Added support for automatic custom kernel loading. Simply drop your kernel with other files. The kernel file must be named "mach_kernel" in order to be included automaticly in the boot.plist file. If not you will have to edit the plist yourself.

- "1" Added Legacy / Default options, selection of GraphicsEnabler and EthernetBultIn options et original ArtWorks. Also some code cleaning and optimizing.

- "1.1" Added Erase/Burning features, more chameleon options, code refactoring & optimizations, GUI enhancements. BootCDMaker is now fully compatible with 10.5 & 10.6.

- "1.1f" Added choice to Burn or Erase & Burn. Previous version was always erasing and then burning...

- "1.2" The app now supports spaces in path, BootCDMaker should now run from mostly everywhere. Added plist correction in case you remove DSDT, Kernel or smbios.plist from "Extra Contents" but leave the boot.plist. Added device-propeties edition and an options to remove chameleon GUI. Removing chameleon GUI should fix EBIOS errors for everyone, i hope

- "1.5" Now with COCOA GUI and a lot more options, bootloader updated to PCEFI v10.3.

- "1.6" EBIOS errors fixed, Disable CHameleon GUI has been removed. ISO should works fine from all type of media now. (Thanks to iNDi)

- "1.6.1" Fixed a bug who was preventing GraphicsEnabler to work properly, thx to stellarolla who has noticed that bug. BootCDMaker will also check if you've made a bad configuration to prevent GraphicsEnabler and or EthernetBuiltin injection to fail. I've also improved the legacy ISO part, no more EBIOS errors in this mode too. And now every features of the software should work fine with spaces in paths names.


Enjoy this little piece of software

Warning: internals ahead

We've arrived at the start of the customary "internals" section. Snow Leopard is all about internal changes, and this is reflected in the content of this review. If you're only interested in the user-visible changes, you canskip ahead, but you'll be missing out on the meat of this review and the heart of Apple's new OS.

64-bit: the road leads ever on

Mac OS X started its journey to 64-bit back in 2003 with the release of Panther, which included the bare minimum support for the then-new PowerPC G5 64-bit CPU. In 2005, Tiger brought with it the ability to create true 64-bit processes—as long as they didn't link with any of the GUI libraries. Finally, Leopard in 2007 included support for 64-bit GUI applications. But again, there was a caveat: 64-bit support extended to Cocoaapplications only. It was, effectively, the end of the road for Carbon.

Despite Leopard's seemingly impressive 64-bit bona fides, there are a few more steps before Mac OS X can reach complete 64-bit nirvana. The diagrams below illustrate.

Mac OS X 10.4 Tiger	Mac OS X 10.5 Leopard	Mac OS X 10.6 Snow Leopard

As we'll see, all that yellow in the Snow Leopard diagram represents its capability, not necessarily its default mode of operation.

K64

Snow Leopard is the first version of Mac OS X to ship with a 64-bit kernel ("K64" in Apple's parlance), but it's not enabled by default on most systems. The reason for this this is simple. Recall that there's no "mixed mode" in Mac OS X. At runtime, a process is either 32-bit or 64-bit, and can only load other code—libraries, plug-ins, etc.—of the same kind.

An important class of plug-ins loaded by the kernel is device drivers. Were Snow Leopard to default to the 64-bit kernel, only 64-bit device drivers would load. And seeing as Snow Leopard is the first version of Mac OS X to include a 64-bit kernel, there'd be precious few of those on customers' systems on launch day.

And so, by default, Snow Leopard boots with a 64-bit kernel only on Xserves from 2008 or later. I guess the assumption is that all of the devices commonly attached to an Xserve will be supported by 64-bit drivers supplied by Apple in Snow Leopard itself.

Perhaps surprisingly, not all Macs with 64-bit processors are even able to boot into the 64-bit kernel. Though this may change in subsequent point releases of Snow Leopard, the table below lists all the Macs that are either capable of or default to booting K64. (To find the "Model name" of your Mac, select "About This Mac" from the Apple menu, then click the "More info…" button and read the "Model Identifier" line in the window that appears.)

For all K64-capable Macs, boot while holding down "6" and "4" keys simultaneously to select the 64-bit kernel. For a more permanent solution, use the nvram command to add arch=x86_64 to your boot-args string, or edit the file /Library/Preferences/SystemConfiguration/com.apple.Boot.plist and addarch=x86_64 to the Kernel Flags string:

...
        <key>Kernel</key>
        <string>mach_kernel</string>
        <key>Kernel Flags</key>
        <string>arch=x86_64</string>
...

To switch back to the 32-bit kernel, hold down the "3" and "2" keys during boot, or use one of the techniques above, replacing "x86_64" with "i386".
