I'll report > back how that goes. (I'm still waiting for the torrent to finish.) Check the Anaconda archive at RH, I think I saw an aside about something like this earlier today. I think one is supposed to be able to install _to_ USB disk. Presumably if the installer on the CD can find it for one purpose, it can find it for the other. There's also a boot image for booting _from_ USB disk. Presumably that can find it;-) -- Cheers John -- spambait 1aaaaaaa at coco.merseine.nu Z1aaaaaaa at coco.merseine.nu Please do not reply off-list
