Syslinux is a collection of boot loaders for Linux and other operating systems which operates on Linux ext2/ext3 filesystems, MS-DOS FAT filesystems, network servers using PXE firmware, or from CD-ROMs. Syslinux has an advanced extension API and contains two optional menu systems. It also includes MEMDISK, a tool for booting legacy operating systems from non-traditional media like PXE or CD-ROM.
