This was very helpful. I was recently helping a friend and was able to resolve a conflict, but up until seeing this video, I don’t think I really got HOW I did it. Now I see it clearly. You do an awful lot of good with these videos. Thanks for putting them together. I appreciate your time and care.

Jared -

It’s clearly Direct Memory Access, but my brain hiccuped when I made the slide. I’ve already updated the mistaken name in my 2009 materials, so look for updates for those after August.

When talking about DMA you said Direct Memory Access, but your slide showed Direct Memory Address …
