Purpose
As a software interface for graphics hardware, OpenGL renders multidimensional objects into a framebuffer. The Microsoft implementation of OpenGL for the Windows operating system is industry-standard graphics software with which programmers can create high-quality still and animated three-dimensional color images. The version of OpenGL described in this section is 1.1.
For information about OpenGL ES running on Windows, see ANGLE for Windows Store.
Where applicable
OpenGL is built for compatibility across hardware and operating systems. This architecture makes it easy to port OpenGL programs from one system to another. While each operating system has unique requirements, the OpenGL code in many programs can be used as is.
Developer audience
Designed for use by C/C++ programmers, OpenGL requires familiarity with the Windows graphical user interface as well as message-driven architecture.
Run-time requirements
For more information on which operating systems are required for a particular function, see the Requirements section of the documentation for the function.

For a game I need OpenGL 2.1 or higher, but I want it to run on my good old Win XP box with an ATI Radeon 9200SE graphics card. It currently seems to have OpenGL 1.3.1008 WinXP Release and graphics driver version 6.14.10.6542 installed.
Searching for OpenGL 2.1 to download only resulted in several downloads of version 1.1 for Windows 95.
Do I need a separate OpenGL installation/upgrade or has it to be included into my graphic card driver? Where can I get it?

OpenGL can't be 'upgraded', and it must be included with your graphics driver. OpenGL exposes GPU hardware capabilities to the operating system. If your GPU hardware were more capable, it could support later revisions of OpenGL on Windows XP with a newer AMD Catalyst device driver package. But your hardware is at least 6 or 7 years too old to support that.
Now, emulation of any revision of OpenGL on the CPU is possible. However, the reason that GPUs exist is that they can compute graphics operations much faster than a CPU of the same generation. For any game, whether it's simple 2D or not, my rule of thumb is, you can run its 3d renderer in software with a high-end CPU from 10 years in the future. So for an OpenGL 2.1 game, it would've had to have been released no earlier than July 2006 (since that's when OpenGL 2.1 itself was finalized), meaning we could start to see playable framerates (30 - 60 fps) when rendered in software with an optimized OpenGL 2.1 implementation on a current-gen CPU.
Of course, on current-gen Intel and AMD CPUs, we almost always have an on-die GPU that's more than capable of running an OpenGL 2.1 game, anyway, so...
Indeed, the mesa3d project maintains such an optimized software renderer as part of its project, but support for Windows is an afterthought, and building it is a bear. Additionally, they don't guarantee good performance or even correct behavior unless your CPU has SSE2 and SSSE3 and SSE4.1. A CPU contemporaneous with a motherboard with an AGP slot (something like a Pentium 4, yeah?) may have SSE2, but probably not the others.
Unless you have a high-end, modern CPU from the past 3-4 years, like a Core i7 3770K or better, you're not going to be able to emulate OpenGL 2.1 in software at a playable framerate. Not even for a very old game. Given that your CPU is probably as ancient as your GPU, you're completely out of luck. That GPU is completely 'fixed-function' and does not support user-submitted code. OpenGL 2.1 runs almost any arbitrary operations on the GPU when submitted as a fragment shader. You can buy an ARM System on Chip for $1 with a GPU 1000x better than that RV280.
You're better off upgrading.
allquixoticallquixoticThis is an old card from 2003 build around the RV280 GPU.Searching on this GPU we find that it supports OpenGL 1.4. That means no hardware support for OpenGL 2.1.
You either need a new card, or you need to emulate this in software. Emulating can work but will be very slow, making it a poor choice for gaming.
