Old situation:
Warning: The partition table looks like it was made
for C/H/S=*/255/63 (instead of 77545/16/63).
For this listing I'll assume that geometry.

Input in the following format; absent fields get a default value.
<start> <size> <type [E,S,L,X,hex]> <bootable [-,*]> <c,h,s> <c,h,s>
Usually you only need to specify <start> and <size> (and perhaps <type>).
