Comment:

 Patch applied in hrev50577. It matches what I read at
 http://wiki.osdev.org/Partition_Table:

  * For drives bigger than 8GB, generally the CHS fields are set to
 Cylinder = 1023, Head = 254 or 255, Sector = 63 -- which is considered an
 invalid setting.
  * Any other illegal value (CHS Sector = 0 or Total Sectors = 0) may also
 indicate an unused entry.
