Boot in Single-Mode

Hi All,
I have AIX 5.1 & I forgot the root password. I find out the solution is to boot in single-mode and remove the root password from the /etc/passwd file. My question is how to boot in single-mode? Also is there any password required when booting in this mode?

NAME
vipw - edit the password file SYNOPSIS
/usr/ucb/vipw DESCRIPTION
vipw edits the password file while setting the appropriate locks, and does any necessary processing after the password file is unlocked. If the password file is already being edited, then you will be told to try again later. The vi(1) editor will be used unless the environment variable VISUAL or EDITOR indicates an alternate editor. vipw performs a number of consistency checks on the password entry for root, and will not allow a password file with a "mangled" root entry to be installed. It also checks the /etc/shells file to verify the login shell for root. FILES
