To use the disc (assuming you left the label for the kickstartboot as ’ks’), you should boot and type "ks" at the prompt. When you hit enter, the kickstart shouldbegin.4.4.10.10. Integrating Kickstart with PXEIn addition to CD-ROM-based installs, RHN supports kickstarts through a Pre-Boot Execution Envi-ronment (PXE). This is less error prone than CDs, enables kickstarting from bare metal, and integrateswith existing PXE/DHCP environments.To use this method, you should make sure your systems have network interface cards (NIC) that sup-port PXE, install and configure a PXE server, ensure DHCP is running, and then place the appropriatefiles on an HTTP server for deployment. Once the kickstart profile has been created, you may use theURL from the Kickstart Details page, just as you do for CD-ROM-based installs.To obtain specific instructions for conducting PXE kickstarts, refer to the PXE Network Installationschapter of the Red Hat Enterprise Linux 3 System Administration Guide.TipUpon running the Network Booting Tool as described in the Red Hat Enterprise Linux 3: SystemAdministration Guide, ensure you select "HTTP" as the protocol and include the domain name of theRHN Satellite Server in the Server field if you intend to use it to distribute the installation files.4.5.
