If you have an IBM Power Systems line of computers, then you will probably use the OS/400 operating system to make the PC functional. In 2008, the developer IBM announced that it was integrating the OS400 and AS400 into one package, called the IBM iSeries operating system.

When you buy a business computer from IBM, you’re going to find that the OS400 comes as part of the basic package. If you want a different operating system, you’ll have to purchase and download a compatible version.

1. Find out the features of the OS400 software. You’re going to want to look at features, specifications and how to use OS400 commands during operation.

2. Download OS400 operating system onto your computer if it does not come standard with your basic software package. If you determine that you would like the iSeries OS400 operating system for your office, you can find a download for your computer.

3. Decide on an OS400 upgrade. If you have the older version of the OS400, then you’ll want to switch over to the new integrated iSeries OS400 offered by IBM.
