Dear All,

I have learnt yet another thing, which is how to incorporate changes in
GRUB2, thanks to "mcduck" in this page (
http://ubuntuforums.org/showthread.php?t=1305116) for throwing up the hint.
About incorporating the change in GRUB2 (in Ubuntu 9.10 Karmic Koala) for
the "noapic" kernel boot parameter, so that the boot line is not required to
be edited everytime the system is booted, the following steps are the
resolution.

Open up Terminal, and type in "sudo gedit /etc/default/grub". Then, type in
your password for authentication, and if done correctly, you will find the
text editor open up. Find this line GRUB_CMDLINE_LINUX_DEFAULT="quiet
splash" (should be the 9th line from the top), and add "noapic" at the end
of "splash", so that the end result looks like
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noapic". Save the changes by
Crtl-S, or click on File>Save, and once saved, close the file. Then, type in
the Terminal "sudo update-grub", and after the update is done (should not
take more than 8-10 seconds), reboot the system. Process complete.

Now, you shall not need to change or edit any more files or entries, and
this should stay. But once you perform a kernel upgrade, then I would
suggest to re-perform the same steps after booting into the new kernel, if
in case wireless functionality is lost after the kernel upgrade.

That's all for now folks. Got to get back to studying Law, examinations
starting next week. Till then, take care, and God Bless. Happy Ubuntu-ing.
