I was putting together a computer with athlon 1 gig and fic az11e board and noticed that both the 12x burner and the 12x dvd always showed up as ata/33 in the bios (before loading the os). Is this the normal rate? or should it be at something like ata/66? I never noticed with my own computer, which happens to say mode 4 or something, but I'm having trouble with both dvd playback and burning on this new computer. could this be the reason?
