Sounds like you are pretty much where I am. To summarize where that is.
I can create a working tree, use mkisofs, and mkhybrid to generate a
working CD from this tree. I can then modify this tree to acomplish
what I want.
I understand that (at least follwong this set of guidelines) the way that
booting workis is that the CD needsa "bootable floppy" image placed on
I can't seem to create a working "bootable floppy image" for this, but if
I copy the one of the ISO providedat that site I can make things work.
So the 2 things I need to understand are:
1. How do I create this "bootable floopy image"?
2. How is this image "pointed to" in the CD image creation?
I beleive I have a handle on the rest of this.
