Installing Mac OS X using only two USB drives

[popoffka]

Hello,

 

What I have is:

• a 20 GB USB hard drive;
  
• a 4 GB USB flash drive;
  
• Acer Extensa 5220 laptop
  
  • Intel Celeron M 550 @ 200 MHz
    
  • 2 GB RAM
    
  • Intel GMA X3100
    

 

And what I want is to install Mac OS X (10.6, preferably) on the listed laptop using only these two drives (I already have an .iso image of Mac OS X Retail DVD). By the way, my laptop is able to boot from both of them, if that is important.

Is there any guide to doing what I want?

 

Thank you very much in advance,
