Description:
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.
