Ah, I see. Well, see... the thing is... I didn't actually install Amahi directly onto the Acer box. And another thing, provided you have USB ports, you don't need a keyboard and/or mouse port. PS/2 ports belong in a museum
So the very important line in my blog post reads:
First, I removed the boot drive and chucked it into a spare box, an Iwill XP4 Evo with a SATA card.
One of the advantages of Linux is that provided the architecture is the same, you can pretty much move the boot drive from pc to pc and it's no big drama. This isn't the case with Windows where the HAL will tend to implode.
The only big caveat, then, is the network interface. When you install on another box, "eth0" will be assigned to the mac address of whatever's in the temporary box. I provide to-be-sure instructions on how to sort that out.
Then there's little things like the hard drive lights and such that need to be done to finish off the install, trust me - it looks a lot harder than it really is.
The reason I needed to eventually hook up VGA and
USB keyboard was because of my own stupid fault - I thought I'd jumpered the debug jumper but I'd actually jumpered the CMOS. FAIL.

This set the BIOS date back to something like 2007, Fedora was complaining about file timestamps being way out of whack and it was subsequently demanding a fsck, so that part of the blog can be basically ignored. I'm going through the post and clarifying bits here and there, so I'll add the above admission sooner or later.
I would still recommend that you eventually get the debug board though, sometimes it's just plain easier to get direct access...
