I have coppied freesco onto the hard disk and every time i try boot it i get this message "unable to mount root fs on 01:00" does anyone know what it means.

I'm not familiar with Freesco but on a brief look it appears to be an add on networking product. I didn't find any mention of "mount" or "fstab" on its site so its not clear why it would have anything to do with mounting.

Mounts are set up in /etc/fstab. The message appears to suggest you are trying to mount the filesystem "/" (a/k/a "root") on a device called "01:00". Normally there is no such device - in fact it appears to be timestamp to me.

Based on foregoing I'd suggest your fstab is messed up.

Are you getting a prompt at all or is it just stopping at this message?
