How do i know i'm running sata ??

i've a lenovo y410 laptop which comes with vista. so i downgraded to xp, for which i used a slipstreamed installation disk. everything's up &running fine. but the problem is, the sata drivers i had slipstreamed were intended for dell inspiron 1420, which i never ended up buying. now how do know if my drives are actually running in sata mode??

p.s. - i installed xp sp1.
