Re: dvd slow and slows clock
I seem to recall setting the dma. I think there may have
been some problem with that in relation to the promise controller.
I'll revisit that. By the way, the hardware works great if I put in a
usb-2.0 mass-storage external case. I wonder why not using dma would
slow the clock down, etc...
