I am using Beta 2 on 2 GHz MBP with 2 MB memory. I was trying to install a program from the CD. I started with Beta 1 and XP keep freezing. Install Beta 2 and the only way I can boot windows is pointing the CD to the XP iso image I used to install windows. It usually stops of the windows logo during the boot if I have the PW set to the real CD. Great product. I think schools will buy a millions of license.
