-The first sector on a floppy disk contains the master boot block (GRUB

 The first sector on a hard disk contains the master boot block, which contains
 the master boot program and the \fBFDISK\fR table, named for the \fBPC\fR
 program that maintains it. The master boot finds the active partition in the
 \fBFDISK\fR table, loads its first sector (GRUB \fBstage1\fR), and jumps to its
 first byte in memory. This completes the standard PC-compatible hard disk boot

 An x86 \fBFDISK\fR partition for the Solaris software begins with a

 the standard Solaris disk label and volume table of contents (VTOC) in the
 second and third sectors, and GRUB \fBstage2\fR in the fiftieth and subsequent
