Leopard OS X on Intel Machine

[zexx0r]

Aight, so I bought an external hard disk with a capacity of 500gb.

 

I want to install Leopard OS on my external hard drive, and be able to

choose which OS I want to boot. Dualboot basically

 

My laptop:

 

Fujitsu Siemens ESPRIMO Mobile V5535

Intel Dual-Core CPU T2370 - 1.73 GHz

2 GB of RAM memory

120 GB of HDD on laptop + 500 GB on external HDD

Running Windows 7 Ultimate, build 7000

 

Please, if someone could give me a link to tutorial, or explain shortly how to do this,

I would really appreciate it
