It sounds as if you had the first drive (Vista) set to boot Vista when you
installed XP on the second drive. XP then wrote a boot sector, ntldr and
boot.ini on the first drive, to boot XP on the second drive. Result is that
neither drive will boot a standalone operating system. What you are doing
now, is booting from the first drive, which then loads XP from the second
drive. Messy.
While you can configure your hard drives the way you describe, and use the
BIOS to select the operating system, it is not that hard to use the Vista
Boot Manager to accomplish the same thing. A program called bootsect.exe on
the Vista install DVD can be used to restore the Vista Boot Manager to drive
1. Then you can use another one called bcdedit.exe to load ntldr and boot
XP from drive 2. Then you will be booting either Vista or XP from the same
boot time menu. Look for articles about bcdedit and bootsect on TechNet.

There are third party solutions to automate the process. No doubt someone
will suggest one or more of those. I haven't found it necessary to use one.
Vista Boot Manager is somewhat like XP boot.ini, except that it uses a
database, very mumbo jumbo, and you have to use a program to modify its
parameters. Not a big deal once you read the TechNet articles.
Now if you want you can configure your drive 2 to boot standalone when
selected as the BIOS boot device. This step is not necessary, but (1) make
it the boot device in BIOS setup and (2) run XP setup CD, emergency repair
process, recover console, commands fixboot and fixmbr. Now you can use the
BIOS to select the boot drive, but as I said not the most flexible option.
