 ===== Boot Loader ===== ===== Boot Loader =====
-There are many boot loaders around. Slackware uses SYSLINUX to boot from install media, installs LILO to boot installed system, provides GRUB-legacy package in /extra (32 bit only). Many distributions use GRUB (renamed from GRUB2) as they main boot loader. If you use a Linux system you probably already have suitable one. You need to put bzImage and initrd.img to right place and instruct boot loader to boot them. \\ Note parameters passed to kernel in ''/isolinux/isolinux.cfg'', you need them to properly configure your boot loader.+There are many boot loaders around.
