Got a new KT7E today, installed it, boot up, everything was fine untill the IDE detecting thing pop out. The bios somehow cannot detect my dvd rom and cd burner, so i went into the bios and set it to auto, reboot, this time it only detected my cd burner, so i shut it down and check the cable and everything, everything is correctly installed. Do u guys know what is wrong?

P.S. one weird thing, on the start up screen, it detected my HDD and CD burner, but when i am in windows, there is only c drive (which is HDD).
