NAME

     cpu_rootconf, rootconf, setroot -- root file system setup

SYNOPSIS

     #include <sys/types.h>
     #include <sys/systm.h>

     void
     cpu_rootconf(void);

     void
     rootconf(void);

     void
     setroot(device_t bootdv, int bootpartition);

DESCRIPTION

     The cpu_rootconf() is a machine-dependent interface invoked during system bootstrap to determine the root file system device and initialize
     machine-dependent file system state.  cpu_rootconf() provides the global variables booted_device, booted_partition, booted_startblk and
     booted_nblks and invokes the machine-independent function rootconf which rootconf then calls the function setroot to record the boot/root
     device and the boot partition information for use in machine-independent code.

     For disk boot, if booted_nblks is not 0, then booted_startblk and booted_nblks are supposed to specify a disk wedge that is used as the root
     device.  Otherwise the booted_partition is used.

NAME

       installgrub - install GRUB in a disk partition or a floppy

SYNOPSIS

       /sbin/installgrub [-fm] stage1 stage2 raw-device

       The installgrub command is an -only program. GRUB stands for GRand Unified Bootloader.

       installgrub  installs  GRUB  stage  1  and  stage  2  files on the boot area of a disk partition. If you specify the -m option, installgrub
       installs the stage 1 file on the master boot sector of the disk.

       The installgrub command accepts the following options:

       -f

           Suppresses interaction when overwriting the master boot sector.

       -m

           Installs GRUB stage1 on the master boot sector interactively.

       The installgrub command accepts the following operands:

       stage1

           The name of the GRUB stage 1 file.

       stage2

           The name of the GRUB stage 2 file.

       raw-device

           The name of the device onto which GRUB code is to be installed. It must be a character device that is readable and writable.  For  disk
           devices,  specify  the  slice  where  the  GRUB  menu  file  is  located.  (For Solaris it is the root slice.) For a floppy disk, it is
           /dev/rdiskette.

       Example 1: Installing GRUB on a Hard Disk Slice

       The following command installs GRUB on a system where the root slice is c0d0s0:

       example# /sbin/installgrub /boot/grub/stage1 
                /boot/grub/stage2 /dev/rdsk/c0d0s0

       Example 2: Installing GRUB on a Floppy

       The following command installs GRUB on a formatted floppy:

       example# mount -F pcfs /dev/diskette /mnt
       # mkdir -p /mnt/boot/grub
       # cp /boot/grub/* /mnt/boot/grub
       # umount /mnt
       # cd /boot/grub
       # /sbin/installgrub stage1 stage2 /dev/rdiskette

       /boot/grub

           Directory where GRUB files reside.

       boot(1M), fdisk(1M), fmthard(1M), kernel(1M), attributes(5)

       Installing GRUB on the master boot sector (-m option) overrides any boot manager currently installed on the machine. The system will always
       boot the GRUB in the Solaris partition regardless of which fdisk partition is active.
