I have a very weird issue with isolinux. I create disks with a bootsector, kernel etc. The CD's boot fine on most machines, but on a significant number the bios just completely ignores them. Yet these same bios's boot a number of linux CD's all using isolinux. Moreover a lot of time the same bios will fail with a CD, yet boot the same iso if it's burned onto a DVD. The only difference I can see between my disks and these vendor disks is that my initrd is rather larger - it's a 26mb squashfs image. Can this be the problem ? Or is there something else I can do - that maybe doesn't require me to redo six months of work :p I certainly would prefer not to redo it unless I know it's the problem. The only other CD I've seen that has the same problem in the same places is mandrake 9.1 which is an older release of course - but their initrd is pretty standard. If I'm missing something obvious I appologise but I'm honestly stuck here. If needed I'll provide any files you may want to look at.
