The best way to describe the Haiku OS is right from their website. So, I quote it :
Haiku is a new open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
I installed Haiku on my laptop. The installation was done inside Virtual Box. The installation was an easy ride, with an interactive interface, though the partition setup was a bit tricky.
You can download Haiku from : http://www.haiku-os.org/
Step 1 : Create a new virtual machine (in Virtual Box) and mount the iso image of Haiku.
Step 2 : Power On your VirtualMachine and the Haiku installation wizard automatically runs.
Step 3 : Continue to the “Installer”. Choose “Setup partition”.
Step 4 : Inside “DriveSetup”, click on your hard disk, then click on the “Partition” option in the menu bar. Under “Initialize”, select “Be File System”, and now you are done setting up your partitions. So, close the “DriveSetup” (the close option is in the yellow tab above the window).
Step 5 : In the “Installer”, select the “Onto” target as the filesystem that you just made. Now, click on “Begin” and you are done. The installation gets over in 5 mins.
I liked Haiku, for being extremely light, and having a myriad of options and applications. I have only tasted the tip of Haiku, and I guess there is a lot left in it for me to try out.
Important Step : To shut down your Haiku, click on the top right hand corner of the screen (the blue feather), and you get the option to shut down your machine.
Networking : To access the network of your host machine (when running in VirtualBox), you need to set the Network adapter type as intel.
Settings -> Network -> Adapter Type : Intel xxx Desktop
Now, you can ping from inside your Haiku shell and check if your network interface is working or not. (or use ‘ifconfig’)
