Re: bootxx needs to fit within 0th track of MBR partition?

A note on the "fit within 0th track" requirement, which most reading
probably already know, but may be interesting to others.

A PC BIOS requires Cylinder, Head & Sector values for disk access
calls, and keeping everything in the same track avoids the need for
code to deal with different track sizes, and even code to deal with
different cylinders at all, which is handy in the rather space
constrained MBR area (446 full 8 bit bytes of code space)
