4 Processor-Specific Boot Instructions for Full Installations

To invoke a full default, custom, or cloned installation of the Digital UNIX operating system software, you boot your processor or single-board computer from the installation media - either CD-ROM or over a network connection to a RIS server.

This chapter provides processor-specific boot commands to boot from the Digital UNIX CD-ROM or over a network connection to a RIS server.

Note
Unlike other operating systems, you do not boot off the distribution media to perform a Digital UNIX update installation. Update installations are performed from single-user mode at the command line. Refer to Chapter 2 for information about performing update installations.

The goal of this chapter is to provide the information necessary for you to perform the user actions shown in Table 4-1.

Table 4-1: Summary of User Actions

After reading this chapter, you will ...	As shown in ...
Shut down and halt your processor.	Section 4.1
Locate your processor in the table and use the appropriate boot commands to boot your system off the CD-ROM or network to invoke the full installation procedure.	Table 4-2

If you are using a CD-ROM optical disc to boot your system, Section B.1 and Section B.2 describe how to load the CD-ROM into a caddy and disc drive.

If you are booting your system over the network, you are initiating an installation from a remote server. To boot over the network, your processor or single-board computer must be registered as a client on a Remote Installation Services (RIS) server.

4.1 Shutting Down and Booting the Processor

To prepare the hardware for the installation booting process, do the following:

If your system is already running a version of Digital UNIX, you must shut down and halt the processor using a command similar to the following:
# shutdown -h +30 Please log out

In the previous example, the system is shut down and halted in 30 minutes and sends the message Please log out to all logged in users. Consult the System Administration guide or the shutdown(8) reference page if you need more information about shutting down a system.
If you are adding peripheral devices to your system at this time, go to Step 2.
If you are not connecting additional peripheral devices to your system, go to Step 3.
If you are adding additional peripheral devices, turn off your system. Then, connect the peripheral devices while your system is turned off.
- Turn on power to the console terminal and all additional peripheral devices; otherwise, the peripheral devices are not automatically configured by your system.
  If you connect additional peripherals or controllers after the installation, refer to the System Administration guide for instructions about how to reconfigure your system.
- Turn on power to the processor. The console subsystem prints various startup and diagnostic messages and ends with the console mode prompt (>>>).
Before invoking the full installation, make sure your system's firmware has been updated. Firmware update instructions are described in Section 1.4.6.
Boot your system from the console mode prompt (>>>). The boot command you enter depends on the processor and the type of software distribution you are using: CD-ROM or network. The DEC 7000 Series, DEC 10000 Series, and AlphaServer 8000 Series processors can be booted only from CD-ROM.
Note
Be sure to review your console firmware update documentation and perform the firmware update at the appropriate time. If you added peripherals, you may need to run configuration utilities, such as the EISA Configuration Utility (ECU) and RAID Configuration Utility (RCU), as well.

Locate your processor in Table 4-2 and follow the booting instructions in the corresponding section. When you have booted your processor, the default, custom, and cloned installation procedures continue in Chapter 5.

Note
If you have problems booting your system, refer to the hardware documentation for your particular processor. If the problem is not hardware related, refer to the System Administration guide. This guide provides information about boot options such as booting a generic kernel ( genvmunix) or booting an alternate custom kernel.

4.2 Fiber Distributed Data Interface (FDDI) Boot Instructions

Table 4-3 shows the boot commands for booting over the network if your system uses FDDI. Follow the instructions in your hardware owner's guide to update the FDDI firmware before booting over the network.

Table 4-3: FDDI Boot Instructions By Bus Type

Bus Type	Boot Command
EISA (Extended Integrated System Architecture)	`fra0[Table Note 1]`
PCI (Peripheral Component Interconnect)	`fwa0[Table Note 1]`
Turbochannel	`"#/ez0"[Table Note 2]`
XMI (Extended Memory Interface)	`fxa0[Table Note 1]`

Table Note:

Before you boot over the network, your system must be registered with the RIS server and you need to know the hardware address. To determine the hardware address, at the console mode prompt (>>>), enter the show dev command.
In the boot command, replace the number sign (#) with the slot number for your FDDI card. To determine the slot number, look at the slot where your FDDI card is installed and then find the number for that slot.
Before you boot over the network, your system must be registered with the RIS server and you will need to know your FDDI address. To determine your FDDI address, enter the following command:
# t tc # cnfg

Replace the number sign (#) with the slot number of your FDDI card.

4.3 AlphaServer 400 Processors

The following sections describe how to boot an AlphaServer 400 processor from a CD-ROM optical disc and from the network.

You have completed booting your system. Continue the installation procedure with Chapter 5.

4.3.3 Booting from the Network

To boot your system over the network, make sure it is registered as a client on a RIS server. Refer to Sharing Software on a Local Area Network for information about registering a client. The client must be on the same subnet as the server.

The device parameter is the network device from which you want to boot. The AlphaServer 400 processor supports two network adapters: ewa0 and ena0.

4.3.3.1 Booting from a Digital UNIX Server

Use the following command syntax to boot your system over the network:

set device _protocols bootp set device _inet_init bootp

For example, if the device you are booting from with the bootp protocol is ewa0, enter the following commands:

>>> set ewa0_protocols bootp >>> set ewa0_inet_init bootp >>> boot ewa0

Some system information is displayed by the installation software followed by the memory and hardware configurations.

If your initial network boot fails, enter init at the console prompt. If you encounter other problems during the RIS installation, refer to Sharing Software on a Local Area Network for more information.

You have completed booting your system. Continue the installation procedure with Chapter 5.
