I have a Compaq Presario R3410US. I've been trying to buy a used motherboard online (part # 370494-001), but I ran into a problem: THERE SEEM TO BE INFINITELY MANY VERSIONS OF THE 370494-001! They vary as to what componants are included and as to what performace those componants have. I've even heard rumors that some versions of the 370494-001 may not even provide full support to my processor! So... I'm hoping there might be some label on the motherboard that would allow me to instantly know what componants and features it has before I buy it. Thus my question: there is a sticker on the motherboard that says S/C:ABCDEFGHIJ. Some of the letters are crossed out, and some are not. I'm hoping this somehow corresponds to what features the motherboard has. Anyone know?

(And of course, my other question is... if that sticker doesn't specify compatibility, is there some other label that does?)

Thanks!
