1.3.5.4 Booting an OS via network boot
The SKY-8100 supports booting over network via PXE.
To boot an OS via network, please make sure the following BIOS options In the
Advanced: Network Stack Configuration Menu is configured properly:

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 configuration 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
collectively 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.
https://www.debian-administration.org/article/478/Setting
network booting.
Caution!
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 servers in your network.
Note!
The PXE client in the SKY-8100 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 / servers.
