SUMMARY (& question): Please help figure out why my 2100 (4.0D PK 2) didn't boot

I got a few very helpful suggestions. Thanks to everyone who responded:

It turns out that the reason the system wouldn't boot was because many of
the files in /dev were somehow changed from device files to regular files.
The file in specific that was causing the system to freeze was /dev/console.
Its permissions were set as '-rw-r--r--' when it should have been
'crw--w--w-' . I had to rename it and run `MAKEDEV console` to repair it.

HOW COULD THIS HAPPEN?

/dev/console was not the only file with this problem. Most, if not all the
Standard Device Files were damaged this way. I had to remove them all and
run `MAKEDEV std`.

More help would be appreciated. Thanks everyone.

                Hello folks,

                I am hoping you all can help me figure out why my system
didn't boot.

                I was eventually able to get it booting, but only after
restoring from backup. The problem is that to the best of my knowledge,
nothing on the O/S had changed from the time of the backup.

                I need to figure out the root cause for this problem, but am
at a loss. Any insight or suggestions would be greatly appreciated.

                Here is the output of my boot sequence. I will point out
where it stopped.

                The system just sits there waiting at this point. A Compaq
technician confirmed that this is not a hardware problem.

                If there is any further information that I can provide,
please let me know.

                I appreciate any help offered.
