NAME
linux-boot-prober -- Determine boot characteristics of a specified device. SYNOPSIS
linux-boot-prober <partition> DESCRIPTION
The linux-boot-prober utility will try to work out how to boot the linux root partition specified by <partition>. If successful, it will outoput one or more lines of the form: <root partition>:<boot partition>:<label>:<kernel path>:<initrd path>:<kernel parameters> For example, for a system with a kernel at /boot/vmlinuz and an initramfs at /boot/initrd.gz, and with / on /dev/sda2 and /boot on /dev/sda1, the command "linux-boot-prober /dev/sda1" will display: /dev/sda2:/dev/sda1:Linux:/vmlinuz:/initrd.gz:root=/dev/sda1 Some partitions will not be displayed by linux-boot-prober. If a partition is mounted on /, /target, or /target/boot, it will be skipped. SEE ALSO

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.

The system will always boot the GRUB in the Solaris partition regardless of which fdisk partition is active. 24 May 2005 installgrub(1M)
