Title: CF cards and DMA
Post by: orange on July 12, 2008, 11:50:02 PM

found this interesting article on slashdot (http://hardware.slashdot.org/hardware/08/07/12/1851251.shtml)

dunno if it matters much to Amiga IDE ports since most are PIO?

Doesnt matter for Amiga cos as you say ALL Amiga IDE ports are PIO. (Gayle, Buddha, X-Surf, FastATA etc.)

I designed UDMA capable PATA (CF card) interfaces (Both host and device) and I've never come across this yet. Never had any helpdesk calls either (which I would have expected).

Perhaps if a DMA fails then under windows it falls back to PIO and no-one ever complained?
