Bootloader for Linux/i386 using MS-DOS floppies

 SYSLINUX is a boot loader for the Linux/i386 operating system which operates
 off an MS-DOS/Windows FAT filesystem. It is intended to simplify first-time
 installation of Linux, and for creation of rescue and other special-purpose
 boot disks.
 .
 It can also be used as a PXE bootloader during network boots.
 .
 SYSLINUX is probably not suitable as a general purpose boot loader. However,
 SYSLINUX has shown itself to be quite useful in a number of special-purpose
 applications.
