1. Download the boot utility from Software Updates 2010 page.
2. Unpack it:
# zcat boot.20100803.tar.gz | tar x
3. Compare the cksum results with the checksum posted on the Software Updates 2010 page.
# cksum boot
4. Backup the existing boot utility.
If you wish to keep a copy of the existing utility, you'll need to save them to a safe location first, to prevent them from being overwritten during installation.
# cp -vc /boot/sys/boot /oot/sys/boot.`date +"%y%m%d_%H%M%S"`
5. Copy the updated driver to the /boot/sys directory:
# cp boot /boot/sys
6. Make sure that the binaries are executable and that the file's owner and group are correct:
# chmod 775 /boot/sys/boot
# chown root:root /boot/sys/boot
