I tried the above possible options but no luck !!  :( and im getting
out of ideas!.

this is what my console gives me when i tried to login


(none) login: root
Dec 31 17:01:01 (none) auth.info login[63]: root login on 'ttyS0'
Dec 31 17:01:01 (none) daemon.info init: process '/sbin/getty -L ttyS0
115200 vt100 ' (pid 63) exited. Scheduling for restart.
Dec 31 17:01:01 (none) daemon.info init: starting pid 64, tty
'/dev/ttyS0': '/sbin/getty -L ttyS0 115200



(none) login: user
Password:
Dec 31 17:01:08 (none) daemon.info init: process '/sbin/

my /etc/ inittab file is shown below.
# /etc/inittab

any clues?
