cdboot, mfs_root and mount_cd9660

[Geoff Buckingham]

I have now tried this with a 4.9 /boot and still see the same problem.

I also added the atacontrol binary to my mfs_root and tried detachng the
ata channel with the cd re-attaching and re-initialising it.

I still get the same invalid argument error.

As I can't fix this with atacontrol can I assume the problem is with
the initialisation of the kernel by the loader rather than the loader 
leaving the cd in a unknown state?

How is the PXEboot which allows  mount_cd9660 to work differ from a no
emulation cdboot?

Moved to stable as I am now 100% 4.x (was using /boot from 5.2 before)
