Setting up a machine to boot from PXE
For bare metal, it is enough that the machine’s BIOS supports network booting.
On a machine that has an operating system on the hard disk, the BIOS must be configured so that the
network interface card is either the first boot device, or at least prior to the Hard Drive device. The
example below shows one of reasonable BIOS configurations. If you don’t insert bootable media, the
machine will boot from the network.
In some BIOS versions, you have to save changes to BIOS after enabling the network interface card so
that the card appears in the list of boot devices.
If the hardware has multiple network interface cards, make sure that the card supported by the BIOS
has the network cable plugged in.
6.10.6.3
PXE and DHCP on the same server
If Acronis PXE Server and the DHCP server are on the same machine, add to the DHCP server option
60: “Client Identifier” with string value “PXE Client”. This can be done as follows:
C:\WINDOWS\system32>netsh
netsh>dhcp
netsh>dhcp>server \\<server_machine_name> or <IP address>
netsh dhcp>add optiondef 60 PXEClient STRING 0 comment=”Option added for PXE
support”
netsh dhcp>set optionvalue 60 STRING PXEClient

Work across subnets
To enable the Acronis PXE Server to work in another subnet (across the switch), configure the switch
to relay the PXE traffic. The PXE server IP addresses are configured on a per-interface basis using IP
helper functionality in the same way as DHCP server addresses. For more information please refer to:
