That was incredibly simple, it worked the first time.  Sir, you are a
gentleman.  Thank you.

Questions/Issues.

1.  For some reason mkiso 1.14 is corrupting isolinux.bin when my initrd
image is compressed.  I do not think it has anything to do with the
compressed image, but perhaps that the CD image is too small?  I have not
had time to properly troubleshoot this.  Decompressing the memdisk 33MB HD
image is not a problem.  But I thought I'd ask if this is a known issue.

2.  Is it possible to eject the CD ROM from withing the memdisk image
without loading drivers?  If isolinux.bin can find the rest of the CD for
booting, then can something in DOS?

3.  Has any done this with a USB key?
