PXE :
-Preboot eXecution Environment
-The PXE protocol is approximately a combination of DHCP and TFTP, albeit with subtle modifications to both. DHCP is used to locate the appropriate boot server or servers, with TFTP used to download the initial bootstrap program and additional files.
-PXE is proprietary software typically included in most network cards sold today.
gPXE :
-Etherboot/gPXE is very similiar to PXE, except it is an open source project, therefore, the software is free.
-It can be used to enable computers without built-in PXE support to boot from the network, or to extend an existing PXE implementation with support for additional protocols.
-While traditional PXE clients use TFTP to transfer data, gPXE adds the ability to retrieve data through other protocols like HTTP, iSCSI and ATA over Ethernet (AoE), and can work with Wi-Fi rather than requiring a wired connection.
