If the first partition starts on cylinder 0 (which is the most common),
it starts on head 1.  All space on head 0, cylinder 0 is available.  The
maximal number on sectors per track is 63, and that's what is normally
used (old drives may use less sectors).  The first sector is the MBR.
That gives 62 sectors available to the bootloader, i.e. 31k.
