In addition, it provides information about the location of a TFTP server and boot image (pxelinux.0). The Network Interface Card (NIC) of the machine triggers a DHCP request.ĭHCP server intercepts the request and responds with standard information (IP, subnet mask, gateway, DNS etc.). Target Machine (either bare metal or with boot sector removed) is booted. The following steps describe how it works: The PXE-enabled NIC of the client sends out a broadcast request to DHCP server, which returns with the IP address of the client along with the address of the TFTP server, and the location of boot files on the TFTP server. PXE works with Network Interface Card (NIC) of the system by making it function like a boot device. A detailed document on PXE specification can be found at. PXE is part of the "Wired for Management" (WfM) specification, which is part of a bigger PC98 specification defined by Intel and Microsoft in 1998. PXE is an open industry standard supported by a number of hardware and software vendors.
