[GLLUG] triple-booting a Mac with OSX, RedHat (specifically ScientificLinux), and Windows XP

[Emilio Xavier Esposito]

Hi
I'm interested in making my Intel Mac a triple-booting machine with
OSX, RedHat (specifically ScientificLinux), and Windows XP.  I've done
some Googling and found the how-to: http://tinyurl.com/6s8b4h (

).  The instructions appear to be up-to-date and very straightforward.

Does anyone have any experience with this type of setup?

What differences (between Ubuntu and ScientificLinux) can I expect
when I have to backup the MBR?

Are there better methods or instructions available?

Would I be better off using Parallels or VMWare Fusion instead of
triple-booting?

Any other advice is appreciated.

Thank you for your time
Emilio
