Need help with possible easter egg on Independence Day disc 2

It appears that I've found an Easter Egg, but I can't get it to "go." Anybody else found this:

On main menu of disc 2 you can go right to a desktop. On this desk there is a computer to your right. From the lower right-hand corner "main" menu choice, if you push the right select button, you highlight the power switch on the computer. Select this, and the floppy disc slides into the computer, and the image on the computer changes.

But what from there? I have a tough time believing they programed this without having a reward to go to.

Nevermind. Unless you know otherwise ...
This is probably the entry point to the DVD-Rom features. Thanks.

I also posted my plea on the DVD Sewer, and Carl was kind enough to provide the following: "This is from the Digital Bits review:
"Disc Two of this set contains some nifty hidden features. We aren't going to spoil them here, but we'll tell you how to find them. From the Main Menu of Disc Two, access the Data Desk area. When you get there, highlight the "Main Menu" selection and then select to the right to highlight the computer's power light. Press enter, and the computer will come to life with a code sequence (based on one of the important dates in the film). When the animation is done, the "Main Menu" selection will come alive again. Press enter and you'll be delivered back out to the Main Menu... except you'll notice that the Alien Attacker is now powered up and floating. Enter the code sequence you were given on the computer screen (using your remote), and after a cool animation, you'll suddenly be able to access three fun hidden features and the disc's production credits. But that's not all - ID4 has Easter Eggs within Easter Eggs! Once you're inside the spaceship, try entering a couple of the other important dates seen in the film (using your remote) and see what happens. Enjoy!"

Oh, and Carl also dubbed me the "resident smart ass" on the CHUD boards. I'm so proud!
