So you want to apply all the right FixPaks to your OS/2 system, but you don't know where to start. This page is intended to help you figure out where you need to go, and how to get there.

First of all, you need to know exactly which OS/2 product you'll be updating. An OS/2 system consists of several products (or components), and each of them has its own FixPaks:

Base Operating System
The core files that make up the OS/2 operating system itself.
Base Device Drivers
Common drivers for standard devices.
MPTS Adapters and Protocol Services
The core networking subsystem – network protocol drivers, APIs, NIC drivers, and a management framework that ties it all together.
TCP/IP Services
Applications for use with TCP/IP networks such as the Internet.
LAN Services
Several related software products for accessing and sharing devices on a LAN.

These pages describe the latest service levels and FixPaks for each of these products, running under OS/2 Warp version 3 and higher.

Reading the Diagrams

The diagrams on each page show the following information:

The diagrams should be fairly easy to read. Start by identifying the version of the product that you have, and the version of OS/2 that you're running it on. (The OS/2 SYSLEVEL command can help you if you're not sure.) Then, simply follow the arrows to find the latest applicable FixPak.

Some points to keep in mind:

In most cases, I've chosen to only show the very latest available FixPak for each product. There are a few exceptions, in which case you might have a choice of FixPaks (this should be clear from the diagram).

I also don't bother showing minor interim single-APAR patches (like the various MPTS stack fixes, or the standalone LVM updates), partly because it's just too complicated, and partly because they almost always get incorporated into the next full FixPak anyways.

I should note, as well, that these diagrams are all based on the (US) English language version of OS/2. While other language versions (generally) use the same numbering scheme, non-English versions frequently do not have the latest FixPak(s) available.

Finally, the diagrams use a few conventions which you should note:
