Things you need:

1. A bootable CD with a partition management tool like Acronis Disk director or simply windows 98 bootable CD with fdisk or windows 98 bootable floppy in order to use XP boot loader after installing Leopard.

2. Leo4all install DVD(Other releases may work as well. You have to use your own intelligence.)

Now follow the steps carefully:

A. Make a primary partition of at least 8 GB (15 GB recommended as MAC only allows installing software on the OSX partition). Format it as FAT32 from windows if you like. Make sure it is primary and not NTFS. All other partitions are preferred in FAT32 format as MAC cannot write on NTFS format.

B. Now restart your computer and insert the OSX installation DVD and boot from it. Wait about 7 minutes!!!

C. After choosing the language go to Utilities menu and choose Disk Utility. Select the partition you created and format it as MAC HFS+ Journaled. After format is complete close disk utility.

D. Click the continue button and accept the License agreements. Then the most important part comes.

E. Choose Customization and then deselect the additional language translations and printer driver to save disk space.

F. Choose the appropriate Chipset drivers.(In my case Via chipset Driver only!). Remember choose only one.

G. Choose the appropriate Graphic Card driver(In my case choose NVidia kext and nvinject 256 mb kext. SELECT BOTH!!!)

H. Choose the sound card driver(In my case AC97Audio).

I. Choose the Ethernet driver(In my case none)

J. Choose AMD Machine fix and tie machine fix and keep the default kernel.(Vanilla kernel for Intel only! Not tested by me)

K. Now continue with the installation. Choose the OSX drive and keep patience. It will take 18 minutes approx. After that machine will restart.

L. Now you should be at the Darwin boot loader. Choose the Leopard volume and Leopard will start to boot.

M. Now a intro movie will be played and you will be represented with the account creation menus. But in most case this process become an endless loop and account is never created. For that restart the machine manually and at Darwin boot loader before choosing Leopard type –s and press enter. After a short will you will be presented at the root: Type the following to create an administrator account manually with name root.

a. /sbin/fsck –fy

b. /sbin/mount –uw /

c. /sbin/mount –uw /

d. passwd root ##it will ask you to enter a new password

e. touch /var/db/.AppleSetupDone

f. The default login user will be root.

g. After logging in create a standard account from system settings accounts option.

N. Login to the root account and go to applications and run kext helper and install the kext you need(For me ViaRhine and AC97audio). Enter the root user password and select the easy install. Cross your finger and restart the machine.

O. If all is OK then shout vollaaaa!!!

P. Now if you want to use XP boot loader(I don't know about vista) insert a partition manager CD and select the XP Drive as bootable and restart the machine.

Q. Use the chain0 file method to select Leopard. It is located in the install DVD itself. To do this go to XP root drive(C: most cases)and paste the chain0 file(copy from DVD first). Go to system properties by right clicking on my computer and select advanced. Select startup and recovery settings and edit system startup. Type the following at the boot.ini file after XP path:

a. C:\chain0="Mac OS X"

b. Here is a screenshot:






R. Save the boot.ini file and restart. Now you can choose the Mac OS X from XP boot loader. Choose it you will go to Darwin boot loader. Choose the Leopard partition from there MAC will start. You can even use the chain0 method for 2 different hard drive with XP in one drive and MAC in the other. Chain0 file will automatically search for the HFS+ partition on both disks.

Done!!!

Best of Luck!!!
