SP2 / Slipstream question

[Flybywyre]

Having finally slipstreamed SP2 into XPpro and burnt it onto a CD, when I install it on my other box of tricks will I also have to download SP1 and previous patches etc.............or does SP2 contain all the previous fixes / patches and supersede SP1 ?

SP2 'Should have' all the SP1 fixes included according to micro$oft
