title Ubuntu 8.04.2, kernel 2.6.30.6
root (hd0,0)
kernel /boot/vmlinuz-2.6.30.6 root=UUID=3234321-9a0c-bcadaa-e8b3a ro quiet splash
initrd /boot/initrd.img-2.6.30.6
quiet

I I know title means what should be shown at boot up? What are the rest? I assume 'ro' means read only. What is quet and splash? Thanks in advance

Hello! I'm no expert, but I'll give it a try

root indicates which storage device the boot loader should look into for the OS
kernel is the path to the compressed kernel (hence the name vmlinuz, with a z)
initrd is the path to the ramdisk (i can't really explain its role in the boot-up process)

I hope that helps :)

And quiet and splash mean, it will show Usplash on bootup rather than text.

If you just remove the word "quiet" from the line you will still get the splash, together with a minimal text output, which some people prefer.

If you're really interested in learning how the nitty-gritty of Grub works, i'd chill for a few weeks. The new version that will be shipped with Karmic is quite different. No point in stuffing your head with learnings that'll be useless in a few weeks time! :)

Having said that, the actual question you asked is common to both, they're just found in different files.

Hmm Thanks guys. But do any of you know what is meant by ramdisk? And the grub and menu.lst is universal for all linux. Isnt it?

A little history :) LILO (LInux LOader) was used before GRUB (GRand Unified Bootloader). But today GRUB is intended to eventually completely replace LILO. As for ramdisk, someone else might be able to explain :)

True, Ubuntu 9.10 Karmic Koala will be released with a new grubloader

However, it is false that the old grubloader will somehow evaporate from hundreds of millions of fully functioning machines all across the globe

Grub 2 will not automatically replace Grub (legacy) on updates. It will only be installed by default on clean installs in Karmic.

There is a link in my signature line to an introduction to Grub 2.

True, my apologies if I freaked anyone out. Should have been clearer about that.
