Dual Boot Vista and XP

My notebook (Aspire 5630) came with Windows Vista Premium.. There are
some programs I have that will not run in Vista so I would like to set
up a dual boot system with Windows XP Pro as the second operating
system...
Help from Vista seems to imply this is easy.... But... when I try to
install it either just stops.. "or" I get a message to the effect that
the operating system I am trying to install is older that the one that
is currently installed.. DUH..

Any one have any success or can advise in detail how to get a dual
boot system working?

Thanks
Ralph

boot from the xp cd....
