AIX is an open operating system from IBM that is based on a version of UNIX. AIX/ESA was designed for IBM's System/390 or large server hardware platform. AIX/6000 is an operating system that runs on IBM's workstation platform, the RISC System/6000.

AIX Structure

The generality and portability of the UNIX system are achieved at some cost in optimum use of the underlying hardware. We had decided to start with the UNIX system as a base. In view of our requirements, however, we were faced with the question of how best to provide the required enhancements. Two strategies could be followed. One was to rewrite the entire kernel. Although theoretically possible, because of the amount of UNIX knowledge available in IBM at the time, it was unlikely that such an approach would achieve upward compatibility with the standard UNIX system. The other was to provide a set of software services for the kernel and modify the kernel and other functions to exploit the facilities provided by that layer.

Hands on

For the members interested in hands on experience we have an IBM 7043-150 (PowerPC) machine running AIX 5.3 on 32 bit multiprocessor kernel (unix_mp).

Misc notes

  • Depending on the value of Multiboot in SMS menu machine will boot in according to boot list or (if Multiboot=ON) will boot into SMS menu.
  • RSPC stands for “RISC System PC
  • in case you've to reinstall an OS and boot without PS/2 mouse connected, you will probably have problems finishing installation in the “Configuration assistant” that is normally a GUI application. To navigate through GUI dialogues use:
    • Tab key to move focus
    • Space key to click (not Enter as you might presume)


  • 10/2013 - 3x RAM “IBM 256MB 43P 150 Memory 7043 RS6000 RS/6000 RISC 4169” purchased by ruza for 73 USD (3*10+43(shipping)) via eBay, thus RAM upgraded to 1GB
