Disavowed beat me to the punch. I must have been composing while he entered his 'to the point' reply. There is some repetition in my reply then.

As far as I can make out, you need ORCPAK5.ZIP. It seems to have a file in it called Andretti.zip, which should be the app you need.
Now for the bad news. From what I can make out reading through the lesson, it's a very old app. The FS v. 2.12 referenced above is Flight Simulator 2.12 and it's the second part of the lesson. I think Orc said it was from 1985, so I'm sure Andretti is really old too.

The lesson is not about CDROM access, at least not the part about Andretti with the loader and TSR. Orc is talking about floppy disks and obsolete floppies at that. I presume Andretti is a floppy disk image in Orcpak5 and is meant to be burned onto a floppy. If so, and it's a 5 1/4 format, how would you run it? Modern CDROM protections are much more sophisticated.
That kind of protection was done by writing the floppy sectors in an unorthodox manner, so only the app could read the sectors. But Orc's lesson is about old DOS and the TSR's it used (Terminate and Stay Resident). They were drivers that loaded into memory to monitor or control DOS apps. They may still be used in modern DOS boxes, I don't know.
Both the TSR and Loader as provided by Orc are pretty old and he's recommending the use of Debug, an old DOS utility.

That was typical Orc. His thoughts would meander. He's only giving you a basic framework and you'd have to consult with people who have more expertise.
if you're going to code anything, I suggest you step up to a more modern lesson so your code is applicable to 32 bit apps (check Iczelion's programming site). Programming in old DOS and 16 bit Windows apps doesn't seem that practical these days. Others may disagree. You've done well to get yourself through the other Orc lessons, and I worked through some of them myself more than 5 years ago. I moved on because the lessons were getting too old then.
It's up to you, but I suggest you cut your losses and check out some of the many modern lessons out there. You might check the bottom of this forum page for links. The link to the old Fravia site has scads of student lessons and a section on CDROM protection that is more modern than Orc's.
