All of the above are viable so I'll add one more.

  Pull the power from the second drive.  The system now has only one
drive.... this will make it easier to mount. (this might not need to be
done... I did it and it worked for me and never tested the other way.)

   Boot from CD1 push f1 and have the rescue disk mount the drive.
   cd to /mnt/etc
   at the command prompt 
   chroot /mnt/ vipw  (you'll be editing the line that says root.)

   vipw is a special form of vi that only works with password
files...much less hassle here.  the chroot command makes sure you use
and edit the real password file on your disk not the one in RAM.

You'll see the first line and it looks like

root:x:0:0:root:/root:/bin/bash

change it to


root::0:0:root:/root:/bin/bash  

Note:  All I did was remove the x this means a passwordless root.

It will now ask you if you want to edit shadow ... type y and hit
return.

You'll see the first line and it looks like.

root:$1$LiESHE2R$bTsUJ/j3616T/opthAEmV1:12103:0:99999:7:::  

This is the "encrypted" version of your password everything between the
first and second : (colon) is your password remove it so the line looks
like.

root::12103:0:99999:7:::

Save and exit


Now shutdown the box reconnect the second drive and when you boot you
can log in as root without a password.. Then at the command line use
passwd root and give it a new one..

Your mileage may vary but this worked for me.
