Imaging Workstations

We are trying to do imaging manually, because our NIC cards are not PXE
compatible. On our 2.4 Ghz workstations we are experiencing a problem.

We are using a bootable CD. We get the screen for options. We type in
manual. It goes through looking for all the stuff it needs. That brings as
to a bash# prompt. When we type in IMG <enter> The blue screen for imaging
shows up for about 2 seconds, then goes back to the bash# prompt.

Any ideas what is happening and how to correct it?

Thanks!
