I recently read a very interesting article that details the numerous technological advantages that Apple's EFI (Extensible Firmware Interface) has over the basic BIOS that today's Wintel PCs use.
EFI gives Apple the ability to exceed the 4 bootable partition limit that occurs with today's Wintel PCs. EFI controlled computers can have as many as 128 bootable partitions per disk. While not important for the average user, servers running virtual machines or many simultaneous operating systems will find this feature indespensable.
One of the most important items discussed is the added protections that EFI gives to the Master Boot Record (MBR). Security is one of the biggest problems for today's computers, and Apple is definitely doing a fine job attempting to create the most secure operating system/platform/computers in the world today.
The most thought provoking item was mentioned at the end of the post. The article mentions that Mike Bombich has now added Windows support to NetRestore.
Using NetRestore, a Windows XP installation can be pushed out to a Macintosh computer over the network in under 10 minutes (average XP installation image). This is accomplished by pulling the computer out of the box that it shipped in, plugging in the power and network cable, and booting the computer holding down the "N" key on the keyboard.
