iPXE Custom Build

PxeLab embedded boot scripts and multi-architecture build artifacts.

Embedded Boot Script

PxeLab uses custom-compiled iPXE binaries. All binaries embed the same boot script:

#!ipxe
dhcp || goto dhcp_failed
isset proxydhcp/next-server && goto use_proxy

:use_dhcp
set next-server ${dhcp-server}
goto chain

:use_proxy
set next-server ${proxydhcp/next-server}

:chain
chain http://${next-server}:8080/boot/ipxe/script?mac=${net0/mac} || goto tftp_fallback
exit

:tftp_fallback
chain tftp://${next-server}/boot/menu.ipxe || shell
exit

:dhcp_failed
shell

Build All Architectures

# Cross-compile with Docker (recommended)
make ipxe-build-all

# Manual build x86_64 EFI
make ipxe-build           # Non-embedded
make ipxe-build-embed     # Embedded (failsafe)
