Dual Booting XP and Vista on 2 SATA Drives

[myarkangel]

Hello everyone, I am the new guy - myarkangel.

I too need help (instructions) setting up a new system dual boot configuration on separate SATA drives. Also, which OS should be installed first?
Drive 1 - Vista Ultimate 64-bit
Drive 2 - XP Pro
