You could try booting from the XP DRIVE and it might work, it would probably take a while to boot up while it replaces drivers etc or it might not work at all.
I used a drive that I had XP Home installed on on a new motherboard and it worked but they were both ASUS boards and I had to make sure that the drive was readable in the BIOS by connecting it to a SATA port that was IDE Enabled as the normal mode for the new board was ACHI. Once it had booted into the old XP that I had I then installed the ACHI drivers and XP would then boot from a SATA port that was ACHI enabled.
You can but try. Both boards were AMD processors.
If you have installation media and the Key that should be on your machine you could always reinstall XP and make it a dual boot machine either by booting to the drive from the BIOS or using EasyBCD to create a dual boot file.
I can't say much more as the information given is too sparse, old motherboard, new motherboard, processor old and new etc but read this tutorial at the beginning and it should give you a better idea.
Generally when a new motherboard is installed it needs a new install of the Operating system.
