Thanks for that.

It's the config for the video card - it was set to 24 bit depth.
Changing to 8 allows it to boot (it's a Matrox Millenium card). I'm
not overly bothered by the low colour depth (it's going to be a NAS
server for file backup) but is this a common fault with the Matrox
Millenium card?
