Step 3: Set up DHCP

NetBoot requires that you have a DHCP server running either on the local server or

another server on the network. Make sure that you have a range of IP addresses

sufficient to accommodate the number of clients that will be using NetBoot at the

same time.

If your NetBoot server is also supplying DHCP service, you might get better

performance if you configure your server as a gateway. That is, configure your subnets

to use the server’s IP address as the router IP address.

Be sure DHCP service is started.

Step 4: Configure and turn on NetBoot service

You use the NetBoot settings in Server Admin to configure NetBoot on your server.

See Chapter 3, “Setting Up NetBoot Service.”

You turn on NetBoot service using Server Admin. See “Starting NetBoot and Related

Services” on page 44 and “Enabling Images” on page 45.

Step 5: Set up Ethernet address filtering (optional)

NetBoot filtering is done by client computer hardware address. Each client’s

hardware address is automatically registered the first time the client attempts to start

up from a NetBoot disk image. You can allow or disallow specific clients by address.

See “Restricting NetBoot Clients by Filtering Addresses” on page 49.

Step 6: Test your NetBoot setup

Because there is risk of data loss or bringing down the network (by misconfiguring

DHCP), it is recommended that you test your NetBoot setup before implementing it on

all your clients. You should test each different model of Macintosh that you’re

supporting. This is to make sure that there are no problems with the boot ROM for a

particular hardware type.

Step 7: Set up all client computers to use NetBoot

When you’re satisfied that NetBoot is working on all types of client computers, then

you can set up the client computers to start up from the NetBoot disk images.

You can use the client computer’s Startup Disk System Preference pane to select a

startup disk image from the server, then restart the computer. See “Selecting a NetBoot

Boot Image” on page 51. Or, you can restart the client computer and hold down the N

key until the NetBoot icon starts flashing on the screen. The client starts up from the

default image on the NetBoot server. See “Starting Up Using the N Key” on page 52.
