Power off the system, open the covers, and disconnect the battery.
Let it stay disconnected for about 15 minutes with the power off.
Reconnect the battery and power up the machine.  It should boot from
the floppy.  Replacing the motherboard works, too. :-)

While you're in the system, make sure that the floppy drive is
connected to the controller, and that all of the connections are good.
Wiggle them a bit.

The RT thinks you've told it not to boot from the floppy with a
keyboard sequence.  (Or, the floppy is broken.  If the battery trick
doesn't work, call your CE.)

Hopefully, it won't be necessary.

Hope I'm right about this one after being wrong about xxx.se.ibm.com
being nameserved.

Your machine is experiecing the "can't boot from diskette" bug.

The first thing to try is this:
Boot the machine.  Hit the key sequence ctl-alt-a (all 3 keys at once).

Shutdown and try booting from diskette.

If that doesn't work, here is the failsafe approach.  Boot the machine.  Hit
ctl-alt-numpad4 (only works if you have some display connected to the RT that
is not the megapel).  You are now in the VRM debugger.  At the prompt, do the
following:

>al F0008828 F0 [enter]
>g [enter]

You should be back in AIX now.  Shutdown and reboot from diskette.

If that fails (because I said something wrong here or you don't understand
what I'm talking about), power off the machine and take of the front cover.
Disconnect the battery back.  Leave disconnected for 5 minutes or so and then
reconnect.  I think this is messy but it also works.

Good luck.

To question 2:  A hearty NO.  You must install using the program.  It does
lots of stuff to the drives, etc.
