34.5. Configuring the DHCP Server
If a DHCP server does not already exist on the network, configure one. Refer to the Red Hat
Enterprise Linux Deployment Guide for details. Make sure the configuration file contains the following
so that PXE booting is enabled for systems which support it:
allow booting; allow bootp; class ­"pxeclients" { match if substring(option vendor­class­
identifier, 0, 9) = ­"PXEClient"; next­server
<server-ip> ; filename ­"linux­install/
pxelinux.0"; ­}
where the next-server
<server-ip>
should be replaced with the IP address of the
tftp
server.
34.6. Adding a Custom Boot Message
Optionally, modify
/tftpboot/linux-install/msgs/boot.msg
to use a custom boot message.
34.7. Performing the PXE Installation
For instructions on how to configure the network interface card with PXE support to boot from the
network, consult the documentation for the NIC. It varies slightly per card.
After the system boots the installation program, refer to the
Red Hat Enterprise Linux Installation
Guide
