hi Ashutosh,
This is not a bug...Have u locked an entry in grub.conf? Once the entry
is locked, u need to input the pass which is the hash from MD5-crypt. The pass
goes through a one way hash & wont be used for integrity checks....
---------------begin--------------
timeout=2
--> password --md5 $1$toZsA0$1QEtDIPIF2qBxe.SbW7jn0 //input hash here
splashimage=(hd0,4)/boot/grub/splash.xpm.gz
title Red Hat GNU/Linux 9.0 (2.4.20-8)
root (hd0,4)
kernel /boot/vmlinuz-2.4.20-8 ro root=LABEL=/ hdb=ide-scsi
initrd /boot/initrd-2.4.20-8.img
--> lock //lock an OS entry
---------------end-----------------
rgds,
