boot sequence,
PXE boot usually does not allow for OS installation over network as the PXE client
will only load a single file from the boot server. Similarly, booting Linux over network
is usually a two stage process. In the first step, a boot loader such a grub or mini OS
such as SysLinux are loaded via PXE from the boot server. The boot loader or
miniOS then load the actual target OS which usually consists of multiple files which
decompressed and installed into a RAM disk. The detailed process and required con-
figuration of such network install will heavily depend on the target OS and boot loader
/ miniOS used. Please refer to the related documentation available.
PXE boot requires a DHCP server and a TFTP server in the network to complete.
DHCP Server and TFTP server are commonly run on the same machine and collec-
tively referred to as "boot server". Setting up such a boot server implies a couple of
steps. How-to guides for setting up Linux as PXE boot server are available on the
internet, e.g.
Setting_up_a_server_for_PXE_network_booting.
Please note that it is recommended to setup a separate network / subnet for network
booting as the DHCP required for PXE booting may conflict with existing DHCP serv-
ers in your network.
The PXE client in the FWA-1320 sends the system's GUID as part of the DHCP
Request. Some boot servers have mechanisms to automatically configure the target
OS image based on the client system's GUID. Using this mechanism allows to use
the same boot server for network booting of different devices / appliances.
