I was the mentor of this new approach to build a CD using isolinux. Apart from the problems reported afterwards of bad BIOS compatibility in very old systems, this way makes it a very clean way to produce a 'professional' Bootable CD. I do however understand that the original guide as made at a time where CD booting was a Dachstein 'exclusive', and the big number of hacks necessary to make it work seems excessive and complex. Now, with Bering-uClibc, we provide an already working initrd.lrp with IDE support, make the job a lot easier. But as always, the documentation is lagging behind... And it is my fault. As for all the suggestions, I will personally say they do need some fixing. And if you provide a good working solution, we may have it incorporated in our own (Bering-uClibc). As for the minimal boot floppy, I can agree with the concept, although I will not use it myself. But I must admit, it will provide the community a more efective Bootable CD.
