Mike,

thanks, I googled it and found these instructions which did it too.  I 
should have done that first before sending the email but it's late and i 
was frustrated...thanks for the reply.

use the bootdisk that you used to install Linux. At the prompt, you can manually
mount the root Linux partition from your hard drive and remove the root
password.  if your root linux partition is /dev/hda2, use these commands 
after logging in as "root":

  mount /dev/hda2 /mnt
  cd /mnt/etc

edit the "shadow" file to remove root's password.

  pico shadow

At the top of the file, you'll see a line starting with root.  Right after
root, you'll notice the encrypted password information between two colons.  
To remove root's password, you use the editor to erase the scrambled text
between the two colons, leaving a line that looks like this:
root::10266:0:::::

Save the file and reboot the machine, and you'll be able to log in as root
without a password.  then set a new password for root.
