Syslinux

Syslinux is an awesome open-source project that gives you a super easy way to set up a bootloader. This means you can boot different operating systems from local drives, CDs, or even over the network with PXE (Preboot Execution Environment). Pretty cool, right?

Booting Legacy Systems

This tool is perfect for booting older systems like DOS. It was made as a simple replacement for the old LILO and Legacy GRUB boot managers. By default, Syslinux supports a bunch of file systems like FAT, EXT2, EXT3, EXT4, and Btrfs.

Compatibility with BIOS and UEFI

You’ll be happy to know that Syslinux works on both BIOS and UEFI machines. Just keep in mind there are some limits when it comes to UEFI (Unified Extensible Firmware Interface) systems. Installing it on almost any Linux-based system is a breeze since it’s usually available in the default software channels.

How Syslinux Boots

The boot process of Syslinux is straightforward. It starts by loading the MBR (Master Boot Record), then looks for an active partition. After that, it runs the Volume Boot Record (VBR) and loads files like /boot/syslinux/ldlinux.sys as well as /boot/syslinux/ldlinux.c32. Finally, it searches for the main configuration file at /boot/syslinux/syslinux.cfg.

Creating Boot Menu Entries

A typical boot menu entry for Linux-based operating systems includes a MENU LABEL that can be anything you choose (it can even be auto-generated from /etc/issue). There’s also a LINUX line that shows where your Linux kernel executable lives. Plus, it can even boot Windows-based OSes!

User-Friendly Configuration Options

You get an APPEND line to point to your root filesystem and an INITRD entry where you specify the location of the initramfs image file created by mkinitcpio.

Your Go-To Boot Manager

Overall, Syslinux stands out as one of the easiest boot managers to use and install for GNU/Linux. It offers both text and graphical menus! You can enjoy features like automatic boots, chainloading, memtest options, rebooting, power off settings, keyboard remapping, hiding menus when needed, PXELINUX support—all wrapped up in a clear menu layout.
