Weird message when booting + dvd not working ?

I got this message when I boot my system :

odd0: HL-DT-STDVD-RAM GSA-H55N
Press any key to continue …

(Even if I dont press anything, the computer boot normal after few seconds)

But my main concern is that CD/DVD drive open and close but doesnt read anything.
As per window7, all drivers are up to date, gsa-h55n is sopposed to function proprely.

Im sure its a BIOS thing, but im not sure and dont know what to do, please help me….
