(Disclaimer : make yourself a 'dd' image of this drive before trying 

If this truly is software-only, you should determine (perhaps by booting 
to Knoppix, etc) what's actually encrypted and where this software 
starts/ends. You might be able to get away with just replacing the 
bootloader for NT/2K/XP with the one from the CD.

Do you have any more information about what was used to set the boot 
password in the first place?
