"LILO is one of the most widely used bootloaders on multi-boot systems. Another open source alternative coming up is GRUB (GRand Unified Bootloader). We came across GRUB during a Mandrake installation, which brought up this article as we were curious to see what it was and how it could replace LILO."

"GRUB, unlike LILO, is able to read filesystems and recognize kernel images too. While LILO requires the physical location of the kernel on your drive, GRUB does not. Even the latest filesystem ReiserFS is supported. This means that you don't have to re-install GRUB every time you make a change to the config file or install a new kernel. If your BIOS supports LBA then there is also no problem reading beyond 1024 cylinders. There's some good support for network booting of diskless clients. On the other hand, GRUB installation can be a bit of a problem. Maybe we're all too used to LILO or maybe GRUB still has some way to go? Little of both we think."

"GRUB can be obtained from ftp://alpha.gnu.org:/gnu/grub/. The official page where you can look for documentation and FAQ's is http://www.gnu.org/software/grub/ . According to the site, the software hasn't been released publicly and the various releases are merely test releases. We haven't faced problems setting up and booting GRUB but there are several known bugs and missing features that might trip you up. The latest release as of writing this article is and this is what we'll be using here."
