I recently put together the computer that I was talking about in the build thread. Everything is working, it boots nicely, and by using the windows recovery console I can confirm that the DVD drive reads DVDs (in this case it can check the directory structure of the motherboard drivers dvd).
when I set the boot order to dvd drive first and stick in the windows 7 dvd, nothing happens. I get the blinking - cursor at the top left indicating nothing doing. When I check on the recovery console to see what is on the dvd, it displays nothing. Blank. And takes a bloody long time to show it. When I stick the DVD into a windows XP laptop (that I am making this post on) it can see a full correct directory structure.
What the flaming goose.
Btw the recovery console is from an old HD that I plugged in to test.
