Navigating ISO9660 with NASM?

[lee.j.baxter]

Hi folks,

I'm creating a bootloader for my setup CD in NASM, and so far I've got the PVD (Primary Volume Descriptor) stored in a buffer. Now I'm stuck, as I'm not sure exactly how the Directory Records .etc. are structured; how is the one-to-many relationship implemented .etc. as it looks like each Directory Record can only store one Directory/File, so I'm not sure how they all link together in a heirarchy. Could anybody provide me with a basic explaination into how it works, along with some sample code if possible? :confused:

Thanks in advance, Lee.
