can't remember login - help?

Hi, I had my Mac G5 in storage and now can't for the life of me remember my login password. I don't think I have a system's disk, what can I do?

1. put osx install CD or DVD in drive
2. restart with 'c' key down (to boot with CD)
3. choose Change Password
4. enter new password
5. restart without 'c' key down (to boot normally) and test

You can try this:

Creating a new Admin on Mac Os X:
Here's how to reset your OS X password without an OS X CD.
the Working solution for me was to create a new admin
you can create new admin like this by deleting a specific file.

You need to enter terminal and create a new admin account:

1. Reboot
2. Hold apple key + s key down after you hear the chime. (command + s on newer Macs)
3. When you get text prompt enter in these terminal commands to create a brand new admin account (hitting return after each line):

mount -uw /
rm /var/db/.AppleSetupDone
shutdown -h now

4. After rebooting you should have a brand new admin account. When you login as the new admin you can simply delete the old one and your good to go again!
