Hi people, i know this isnt exactly a case mod problem, but i didnt know where else to put it

basically, I just built my first computer, and it all installed fine and everything, vista fully working, but I noticed that my hdd light isnt flashing on my case. now, I have an idea that my motherboard only supports smart something or other hdd light things( thats a technical term) but id like to know whether its something i need to worry about, whether i need to get a replacement motherboard or something. my systems specs are : AMD Phenom x4 2.4ghz, Foxconn A6VMX motherboard, 2 gigs of ram, maxtor diamondmax 120gig sata hdd + a random ide 40gig that i had spare. im using onboard graphics at the mo but im gettin a new graphics card soon :P
thanks.
