I don't understand what this means; does it imply that you can't have a =
multiple operating system with a non-FreeBSD OS ? I have Windows XP =
Professional in primary partition 1 of 4 primary partitions on my hard =
drive. Partitions 2 and 4 are available to accept FreeBSD but won't =
because of that "max one 'fat' allowed as child of whole" message. Is =
there a circumvention to this problem ?
