where X = number of cores of your CPU ;
where Y = bus ratio of your CPU
( lookup table can be found here , missing entry : i5-870 => busratio=20 )
=== PART 7 : Save the kernel flag ===
1. To save the kernel flag permanently , launch Terminal in Mac .
2. Type sudo su [ Enter ]
3. Type in your password [ Enter ]
4. Type in vi /Extra/com.apple.Boot.plist [ Enter ]
5. If you are familiar with vi text editing environment , append the “cpus=X busratio=Y” after arch=i386 in the Kernel Flag section; if not, use arrow keys to navigate to the position after arch=i386, enter the follow key sequences (type only bold keys):
i , cpus=X busratio=Y , Esc , :w , :q , exit
The kernel flag is now saved , i.e. you don’t need to type the kernel flags during boot anymore .
Congratulations ! You’re done !
=== Part 8 : Install bootloader to hard disk ===
Note: this part involves knowledge of hard disk partitioning and disk layout. If you are not sure about what you are doing, just skip this part & use iBoot disc to boot up Mac.
To install Chameleon bootloader, follow the steps:
- Download Chameleon bootloader here
- Extract the archived file ( assume you extract to ~/Downloads )
- Here we assume your root disk is /dev/disk0s1 (if not, change the commands accordingly)
- Gain administrative privileges in Terminal:
- Navigate to extracted folder:
- Install boot0 to MBR:
sudo fdisk -f boot0 -u -y /dev/rdisk0
- Install boot1h to partition’s bootsector:
sudo dd if=boot1h of=/dev/rdisk0s1
- Install boot to partition’s root directory:
sudo cp boot /
