Advanced Installation - Solaris 9 System Administrator - page 380

By default, the install server supports the SunInstall installation program.
However, the install server can be modified to use the Solaris WebStart pro-
gram instead. The modify_install_server(1M) command (located on the
Solaris 9 Installation CD) can be used to copy the WebStart-enabled mini-
root from the CD to the install server configuration.
To modify the install server, insert the Solaris 9 Installation CD into the local
CD-ROM drive and execute the modify_install_server command on the
CD. The following listing shows executing the modify_install_server
command from the mount point of the distribution CD to modify install
server:
# ./modify_install_server /export/install
The modify_install_server command supports the -p command-line argu-
ment, which preserves the existing mini-root by copying it to the
/Solaris_9/Tools/Boot.orig location under the install server configuration
before the CD mini-root is installed.
Boot Server
A boot server is a system that contains the files necessary to boot a SPARC
install client over the network during an over-the-network installation. After
an install client has booted, the boot server has completed its function. The
remainder of the installation is supported by an install server. Because Intel-
compatible install clients boot from a local disk or local CD-ROM, they do
not use a boot server for installation.
Typically, an install server and a boot server reside on the same system. In
fact, when a system is set up as an install server, it is also set up as a boot serv-
er. However, if install clients are on a different subnet from the install serv-
er, a boot server must be set up on the same subnet as the install clients.
A boot server is required to be on the same subnet as SPARC install clients because
the clients obtain booting information from the boot server using the Boot Protocol
(BOOTP) broadcast. The packets of this protocol are typically not forwarded by
routers, which interconnect subnets.
To set up a system only as a boot server, the system must have access to the
Solaris software distribution CD through a local CD-ROM drive or a
remotely shared CD-ROM drive.
The setup_install_server command, under the Solaris_9/Tools directory
on the Solaris software distribution CD, is used to copy the boot software to
the boot server. Two command-line arguments are required. The first is the
