Not enough RAM (only 2 GB) to justify addressing in 64 bit, and no intention to upgrade the RAM (it's hardly used 50%). 2. Some software that works best with 32 bit, especially wine (for games) and nvidia-driver for GPU. 3. Pure lazyness due to "never touch a running system" principle. For sure, I wouldn't do this on a new system, but this is a quite old system (actually ca. 10 years old) and still fully functional for my home use (gaming, video editing, web browsing, office suite, LaTeX, programming, etc.). Also I wouldn't advise running 32 bit OS until you have a very good reason to do so. As you can see, I have provided 3 good reasons... ;-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
