Grrr. Having reported the 4GB of RAM on POST, the server then decided after all that it couldn’t see it and sulked, refusing to install SBS after the initial OS install. So off with the side again to make double-triple sure the sticks are properly seated. Second time lucky, and so far I’ve given my network a name and created my administrator account, and I’m back to watching computer paint dry as it installs updates. This is of course a good thing as it means it’s also managed to connect to the internet.
More later. For those interested; I’m well aware that this is kind of esoteric.
