???HUH??? Figure this if your running a SSSD 8" to be compatable with
media out there the system has two tracks to use for the CCP, BDOS and
bios. Thats 52 sectors!

The first sector DOES NOT HAVE TO BE THE BOOT.
The FIRST 1600h bytes are ccpand bdos (44 sectors).
The bios can be up to 8 sectors in length but the buffers can be placed
on the end so they dont have to be stored in the disk (uninitialized ram).

Infact the system can be in rom and copied to ram and mapped out.
The disk if your going to read SSSD disks must use the skew of 6, 2
tracks reserved with 63 directoriy entries(may be different , from
memory).
