         sector from the first diskette drive, or, if that fails, from the first

  X86 PRIMARY BOOT
-        The first sector on a floppy disk contains the master boot block (GRUB
-        stage1). The stage 1 is responsible for loading GRUB stage2. Now GRUB
-        is fully functional. It reads and executes the menu file
-        /boot/grub/menu.lst. A similar sequence occurs for DVD or CD boot, but
-        the master boot block location and contents are dictated by the El
-        Torito specification. The El Torito boot also leads to strap.com, which
-        in turn loads boot.bin.

         The first sector on a hard disk contains the master boot block, which
         contains the master boot program and the FDISK table, named for the PC
         program that maintains it. The master boot finds the active partition
         in the FDISK table, loads its first sector (GRUB stage1), and jumps to
         its first byte in memory. This completes the standard PC-compatible hard

         disk boot sequence. If GRUB stage1 is installed on the master boot
         block (see the -m option of installgrub(1M)), then stage2 is loaded
         directly from the Solaris partition regardless of the active partition.

         An x86 FDISK partition for the Solaris software begins with a one-
         cylinder boot slice, which contains GRUB stage1 in the first sector,
         the standard Solaris disk label and volume table of contents (VTOC) in
         the second and third sectors, and GRUB stage2 in the fiftieth and
         subsequent sectors. The area from sector 4 to 49 might contain boot
