CPU_ROOTCONF(9) 					   BSD Kernel Developer's Manual					   CPU_ROOTCONF(9)

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. SEE ALSO

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. See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |Interface Stability |Evolving | +-----------------------------+-----------------------------+ 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. 24 May 2005 installgrub(1M)
