I have a Mac Pro 2006 that has 64-bit processors, yet only boots 32-bit operating systems (aside from OSX). Is there a way I can install 64-bit Ubuntu Server, or any 64-bit OS for that matter, on this Mac? I'm getting tired of Snow Leopard Server.
EDIT: Uhm, computer is silver and looks like a cheese grater. It's a Mac Pro 2006 (first gen) with a single 250 GB HDD (original), 2 GB DDR2, and 2 dual-core Xeons.
