Well, just spotted a deliberate mistake.
Having said how easy the partitioning of Vista and W7 was, I now see that I'm limited to shrinking C to no less than 230g out of 500. It seems there are fixed files in it, which they refuse to budge.
I don't want to use a third party's soft, as things like Partition Magic seem to have a lot going on behind the scenes. I get the feeling that their partitioning is done with the aid of smoke and mirrors.
Also...I'm sure that I didn't do a re-install of Vista on my laptop, and that's set out much as I wanted. Perhaps, W7 grabs a bit more space to play in, though with Vista's reputation, that seems unlikely. Just don't know.
Still, this is all a learning period, I'm still having to do a full install with the paid version - all too soon now. If this comes about, I'll make sure my drive is partitioned first.
The five-speaker setup is just what I need. One speaker on each ear, two for the cat, and the huge one to sit on.
However, fine as that might be, I set the soft for something like Super-dooper sound, and I think it's expecting the mic to be the same. It's very feint, and the spare is the same. Maybe the vendor will let me know what the plethora of sockets for sound are all about. Have not yet found the link to the board for a manual. I get A7 GM-S AM2 + 780G RT exactly on Foxconn's site, but then get shoved to a totally wrong page. I'm sure they do it just when I'm looking.
Time for de-caff tea and bikkies.
