my question is quite similar to a recent one but this is a little different scenario. i have an ecs k7zmm mobo with win xp pro os. i want to change the mobo with another ecs brand but with a higher model. can i do the swapping without reformatting the hard disk? and are there any procedures that i should do before replacing the mobo? will win xp just automatically look for changes and adjust itself to the new mobo?
