Here is the procedure for breaking the password:

To assign a new root password when you're unable to log in as root, follow
these procedures:

1. Turn the computer off and then on, using the Power key.

2. During the boot process, immediately after the "Testing System"
message is replaced by the "Loading from disk" message, hold down the Command
bar and press the ~ key (without pressing Shift). On keyboards with two Command
keys, hold down the right Command key and press the ~ key. This displays the
ROM monitor window.

        Warning: If a hardware password has been set, you must supply
this password before you can boot the computer. If you don't supply the
hardware password, you'll be unable to complete the remainder of this
procedure. (For more information on the hardware password, see "The ROM
Monitor" in Chapter 9.)

3. Start up the machine in single-user mode by entering one of the
following commands at the ROM monitor prompt:

bsd -s (To boot from the hard disk)
bfd -s (To boot from the internal floppy disk)
bod -s (To boot from the optical disk)
ben -s (To boot from the Ethernet)

The system starts up, displaying a series of messages. When startup is
complete, you see the single user prompt #.

4. At the single user prompt, start up the system services by entering
the following command:

sh /etc/rc &

You see a series of messages appear on the screen as the rc shell script
executes. During this process, NetInfo is started. You won't see a shell prompt
after these messages unless you press Return.

5. Set the root password. Enter:

passwd root

You're prompted twice for the new password.

6. Turn the system off and then on again. After the system boots, you can
resume normal operation with the new root password.

        Warning: Don't try to continue the boot into multiuser mode. If
you do, you'll start duplicate system services, which will cause a number of
problems. You must halt the system and reboot.


 As regards the 4gig HD, IIRC You are limited to 2gig or less partitions.
