SkyOS This is surprising.

We suggest using VMWare Player (Windows/Linux) or VMWare Fusion (MacOS) to run the Live CD or install the beta. Install SkyOS to your harddisk or run the Live CD natively on your own risk!

To run SkyOS in VMWare just:

  • create a new virtual machine and point it to the ISO image you downloaded
  • give it at least 2GB of RAM
  • use a virtual IDE harddisk (we don't suggest using a physical partition in order to prevent possible data loss)
  • optionally Install SkyOS from the running Live CD to get all available applications and utilities

SkyOS was quite prominent on OSNews between 2003-2008 - it was coded virtually entirely by Austrian Robert Szeleney in his free time. It achieved a relatively usable state on the desktop - especially considering it was a one man project - but it did suffer from what I call the 'ooh shiney!'-syndrome - it was a hobby project for Szeleney, and as such, focus tended to shift around quite often, depending on whatever he wanted to work on at that time.

SkyOS originally started out as a mere bootloader, but eventually expanded into becoming an entire operating system. In the early days - up until version 4.x - SkyOS was freely available, but it wasn't open source (I believe the 1.x versions may have been, though, I can't recall). After that, Szeleney started charging a small fee for access to the SkyOS 5 beta, which some considered controversial. The SkyOS 5.0 release cycle started with its first alpha release in December 2003, and ended with the release of beta build 6947 in August 2008 - a final release never materialised.

The project seemed to fizzle out, but Szeleney did experiment with using third party kernels, like a BSD kernel or a Linux kernel. That was the last we heard of it - and earlier this year, the website went dark.

So, it's quite a surprise to see that over the weekend, Szeleney has made the last beta release of SkyOS 5.0 - build 6947 - available for free. I somehow doubt we'll see development pick up again, but it's nice to have the latest release out in the open for everyone to play with.

Would anyone who has been successful in accessing the ISO let us know if the sources are included? If so, this would help being extremely patient.

Hoping the bandwidth has remained manageable. Let us know of the statistics say one month from now.

The gcc along with the headers and documentation/help are there so one could think of developing applications.

It is unfortunate that this free release did not include the corresponding source - and is not providing any hope of long life. Given this status, this has remained a play-toy.

I downloaded your file quickly and thought I would save you some bandwidth by seeding it through bittorrent.

Thanks for hosting that. I downloaded it and installed it on an old Dell D800 laptop. It didn't support my wired or wireless cards. It did properly detect the nVidia 5200 GPU but I couldn't get it to switch from VESA to the native nVidia driver. SkyOS seemed very much like just another Linux distro minus good hardware driver support so I quickly wiped the partition and installed the latest release of Haiku and was quite pleased that it properly recognized all my hardware and booting in an amazing amount of time....less than 12 seconds on a Pentium-M class laptop. Now if the Haiku devs would just port an office productivity suite....
