/*
 * Use the traditional hp300 layout.  Rationale:
 * - Room at the beginning of the disk to load a small primary bootstrap
 *   if that's what the ROM wants to do.  The bootstrap can encapsulate
 *   the disklabel; installboot(8) simply needs to understand that the
 *   label needs to be preserved.
 * - Room at the beginning of the disk for an MBR table to be there, if
 *   that's necessary for some reason, although we don't do much with
 *   that MBR table other than allow it to exist.
 *
 * The implementation of readdisklabel() in subr_disk_4bsd.c will check
 * this location first, and if not found, will scan the first 3 disk
 * sectors looking for it, and use that same location in writedisklabel()
 * if updating an existing label.
