GUI screen freeze

["Bill Hamlin" <bill vipernetworks com>]

A friend of mine dropped off a server that he had running with RedHat 9.
I plugged in my serial mouse (he had a bus mouse), and everything else.
During the bootup everything works great.  It shows a terminal level
prompt and I can start entering the password, but then the screen goes
to GUI mode.  It takes about 15 seconds, and then the login screen
appears.  But I can't enter the login name.  The mouse is also not
working.

I can't hit any keys, even ctl-alt-del.

This is using "grub" to load.  How do I stop the thing from going into
GUI mode?

Maybe the mouse being serial instead of bus is the problem (the
auto-config detect thing saw the bus mouse was gone and I let it take
that out of the configuration)?

What else could be wrong?

Thanks for any help,
Bill Hamlin
