Installing GRUB on USB stick
--------------------------------
tested on Solaris Express Community Release b20
I wrote this guide for installing GRUB on my USB stick. Maybe someone will find
it useful. Comments or suggestions for improvement are welcome.
The following steps will install GRUB on a USB stick. If the USB stick is
inserted the GRUB menu will appear, if not XP will boot automatically. Remember
to configure your BIOS to boot from USB.

# svcadm disable -t system/filesystem/volfs
