Several new features are included in the new version like: kernel 2.6.28-11.37, Gnome 2.26, and the a-lot-talked-about Ext4 file system. The main focus has been user experience. They have also worked hard on making the system boot faster.

I have gathered some links to other blogs/news-sites if you’re interested in more reading.

Some good sourced in-depth articles:

Who doesn’t like an operating system that boots and opens FireFox in approx 25 seconds?

At first it all went well, until I decided to upgrade from 10.5.5 too 10.5.6. After the upgrade things stopped working, so I chose to install another release called iPC 10.5.6. That of course messed up my bootloader. Read more about how I fixed this.

To get everything working I followed this installation order; first I installed OS X on a 50 GB partition using iDeneb v1.3, after that I installed Ubuntu 8.10 on a same size partition. When you install Ubuntu, grub is automatically set as default bootloader. So the first problem I faced was how to get the OS X installation into the grub bootloader at startup.

Adding a new operating system to the grub bootloader is done by configuring this file.

/boot/grub/menu.lst

Adding OS X into this list was done by inserting these values.

title            Mac OSX Leopard
root           (hd0,3)
kernel        /boot/boot_v8
boot

The boot_v8 is a file I downloaded from a random site and put into the /boot folder. I don’t actually know what the file is doing, all I know is that it must be there.

If you enter grub (with root permissions) by typing sudo grub in a terminal window I will describe a couple of nice commands for you.

Find out where your grub files are located. What is returned is the hard-disk number followed by the partition number:

grub> find /boot/grub/stage1

(hd0,3)

Say you messed up your MBR and wants the grub back in business. First you must know where your grub files are located, which we found out in the command above (find).  We need to tell grub where the files are.

grub> root(hd0,3)

The last step is setting grub as the MBR on the primary bootable device (master hard-drive). When this is done we can quit and reboot. The grub will hopefully pop up when the system boots up.

grub> setup(hd0)

grub> quit

reboot

If you ever mess up your bootloader the Ubuntu installation CD is your savior. Boot up a live session and open up a terminal window and follow the commands above and you’re saved.

I will give an absolute tutorial on how to install OS X on the Compal IFL90 later this month.
