I am asking because a relative just bought a MacBook Air with the SSD drive (64gb). He will need to install BootCamp with XP in order to view the security cameras at his home and office. (For some reason this software will only run in BootCamp and will not run in VMWare or Parallels.) Since the only thing it will be doing is running one program I am hoping to install the smallest XP possible plus this program. Even web browsing will not be done on this install. I dont know what a page file is...
