Nec 2510a

i have a nec 2510a drive w/ firmware 2.16 flashed tourgh dos. but the ripping speed is still 2.1. ive tried 2.06 2.15 and others but got nothing to rip above 2.1x. i just changed fromt a toshiba r5002 that would rip a dvd in bout 15 min. just wondering if theres any more ideas out there.

Check DMA.

yes it says dma when available, and i cant find it on my bios.
