PXE features
PXE (Preboot eXecution Environment) is the predominant standard for network booting on the x86 platform. The facilities provided and required by plain old PXE are somewhat archaic by today's standards.
The open-source gPXE project provides a free (GPL) implementation of PXE with many enhancements not found in legacy PXE implementations, such as:
- iSCSI boot - boot an operating system (such as Linux or Microsoft Windows Server 2003) directly from an iSCSI target.
- AoE (ATA-over-Ethernet) boot - boot an operating system (such as Linux or Microsoft Windows XP) directly from a Coraid Etherdrive NAS.
- HTTP boot - boot directly from a web server.
- Boot scripts - avoid complex multiple-option DHCP configurations and just write a simple script to control the network boot process.
