OS/2 and eComStation IBM pretty much slammed the solid oak door on open sourcing os/2. "As stated in our response to your September 2005 letter we have considered the positioning of os/2 and open source several times in the past, and for a variety of business, technical, and legal reasons we have decided to not pursue any os/2 open source projects."

As I understand it, insanely tight integration with the hardware is one of its greatest strengths.

Really? I just left an IBM shop last year, and while I did not work as the sysadmin, the guy who did lead me to believe that modern IBM machines run AIX in a virtual machine called an LPAR.In fact, he told me that IBM's "best practice" for a machine that is only going to run one instance of AIX, is to run it inside an LPAR, and not on the bare metal.

I was under the impression that virtualization was IBM and AIX's big strength, not tight integration with the hardware...

Well, I'm basically repeating my interpretation of what another member of this forum, for whom I have great respect, has said in the past. And you know how screwed up interpretations can be. So I'll defer to anyone who has more actual experience with AIX than I. ;-)

IBM AIX and Linux do run on bare metal on RS/6000-pSeries-System p and they call the hypervisor ( some kind of enhanced firmware ). AIX nor Linux is not hosted within another OS.
IBM ported AIX to another hardware platform ( Intel IA64 Itanium ) but canceled it.
AIX is tightly integrated with the HW for good reasons. The firmware is Open Firmware ( not PC BIOS nor EFI ).
You can dynamically load device drivers and configure them w/o rebooting. AIX is a POWER (POWER4, POWER5) RISC based OS. It's a vertical integrated platform not unlike the Apple Macintosh platform.
