What's New in the Solaris Express 1/06 Release for Solaris Installation
This section describes the following new installation features in the Solaris Express release.
x86: GRUB Based Booting
Starting with the Solaris Express release, the open source GNU GRand Unified Boot Loader (GRUB) has been adopted
in the Solaris OS for x86 based systems. GRUB is responsible for
loading a boot archive into the system's memory. A boot archive is
a collection of critical files that is needed during system startup before the
root (/) file system is mounted. The boot archive is used to boot
the Solaris OS.
The most notable change is the replacement of the Solaris Device Configuration
Assistant with the GRUB menu. The GRUB menu facilitates booting the different operating
systems that are installed on your system. The GRUB menu is displayed when
you boot an x86 based system. From the GRUB menu, you can select
an OS instance to install by using the arrow keys. If you do
not make a selection, the default OS instance is booted.
The GRUB based boot feature provides the following improvements:
Faster boot times
Installation from USB CD or DVD drives
Ability to boot from USB storage devices
Simplified DHCP setup for PXE boot (no vendor-specific options)
Elimination of all realmode drivers
Ability to use Solaris Live Upgrade and the GRUB menu to quickly activate and fall back to boot environments
