IDE/SCSI Emulation

I'm not a programmer, only a user, so I am not sure if I'll be correct with
what I'm suggesting in this message.

I have a shareware software program which requires an IDE or SCSI hard disk
to authenticate itself as registered by me. When I attempt to run this
program under MOL it complains that it cannot find an IDE or SCSI hard disk
to authenticate itself.

I am not familiar with the registration algorithm, but here is the procedure
I must follow to unlock the program:

1. I install the program
2. I run the program
3. It asks me to authenticate myself with a response key to the challenge
code it offers (the algorithm somehow examines characteristics of the
partition table)
4. I enter in the response key that corresponds to the challenge code
5. The program is then unlocked for me to use

If I were to reinitialize the hard drive, the challenge-response codes would
change, so it obviously has to do with changes reinitializing the hard disk
creates.

This problem is common when running the program in MacOSX classic mode.

Is it possible to create some sort of macos system extension to fake an IDE
or SCSI hard disk to fool the program so I can use it?

For reference, the program in question is Igor Engraver (www.noteheads.com).

For my information, does MOL and MacOS Classic mode emulate an interface
other than an IDE or SCSI when giving the MacOS access to these disks?

Thanks for any help you have!
