SYNOPSIS:     Restoration of the Solaris X86 master boot program

OS RELEASE:   

PRODUCT:      Solaris x86

KEYWORDS:     master boot program partition


DESCRIPTION:

Describes the restoration of the partition choice menu displayed during
the master boot execution. 


SOLUTION:

Occasionally the fdisk program from an operating system other than
Solaris is run on the hard disk.  This act of changing any of the "fdisk
table "data and writing back will replace the master boot program.  Each
operating system has a different notion of the master boot program.  The
Solaris version has the partition selection menu. 

The restoration of the Solaris master boot program requires several
steps. 

1. Use an fdisk program to set the Solaris partition active
   enabling Solaris to boot.

2. Boot the system and Solaris should boot.

3. Run the fdisk program as "root" by entering:

        fdisk /dev/rdsk/c0t0d0p0

4. Change the active partition to any other partition, then back
   to the Solaris partition. This action will cause the hard disk
   to be updated when option 4 (update and exit) is chosen.

5. Choose option 4 from the menu. This will save the changes.

The next time the system is booted the partition boot menu will be
displayed.
