I believe the op already has installed Vista on the second drive, thus a fresh install may not be necessary.
If Vista was fresh installed to unallocated space on the second drive or an existing partition, Vista should create the boot menu
options for dual booting and place the necessary files on the primary o/s(XP) partition.
Since both o/s are present.... Carey's post on using VistaBoot Pro which will allow managing the existing boot entries and the
bootloader, choose the default boot o/s, etc...should suffice(similar to EasyBCD).
Another more flexible and fine program(not discounting Acronis mentioned earlier) is BootITNG(BING).
