When booting a Workgroup Server 95 I get a prompt saying: "Enter run level: 0, 1, 2..."
Any response, except for "0" which brings up the single user mode of A/UX, ends up hanging the computer.
The inittab file has been damaged. It needs to be replaced with a backup copy. If a backup does not exist you can copy it from the A/UX cd using the following command in the startup shell:
cp <scsi id of cd>,0,0/etc/inittab /etc/inittab
Note: One way this condition can be triggered is by editing inittab with TextEditor.
