boot-132 vs grub-dfe

[boreas]

Hello,

 

please excuse my english ;-)

 

I just got my system (EP45-UD3R), and I want to install my first Leopard with Retail DVD. I want to know the difference between boot-132 and grub-dfe method.

I understand that for boot-132 is necessary to create 2 partition on HDD (one for boot-132 and one for OSX). If I will use grub-dfe, it will be necessary to create 2 partition, too, or if I will use grub-dfe I will have just 1 partition on HDD?

Also if I will use boot-132, how big the partition must be?

 

Thank you!
