SYSLINUX is a boot loader for the Linux operating system which operates off MS-DOS floppies. It is intended to simplify first-time installation of Linux, rescue disks, and other uses for boot floppies. A SYSLINUX floppy can be manipulated using standard MS-DOS (or any other OS that can access an MS-DOS filesystem) tools once it has been created; and requires only a ~ 7K DOS program or ~ 13K Linux program to create in the first place. Starting with version 1.46 it also includes PXELINUX, a program to boot off a network server using a boot PROM compatible with the Intel PXE (Pre-Execution Environment) specification.
