Installation guide

Booting 4-27
Some systems use Ethernet-based CD servers to load the operating sys-
tem. The InfoServer consists of one or two CD drives and connects to stan-
dard Ethernet or ThinWire groups or networks.
Before loading the operating system during system installation, a number
of steps are needed to find and connect to an InfoServer. Figure 4-7 illus-
trates these steps. See Section 4.6.2 for information on show network
and boot commands.
Each InfoServer drive has its own address, so either drive can contain the
CD needed to load the operating system. In large system configurations, a
number of InfoServers can be connected to the system. Figure 4-8 shows a
configuration of systems and InfoServers.
