IBM IntelliStation POWER 265

System Type: 9112

Released in 2002 the 265 had some specifications way ahead of its time and was the first in the IntelliStation lineup to feature POWER CPUs (in this case POWER3-II). Its processors had 4MB of *ECC* L2 cache and it could support up to 8 GB of RAM; Intel-based machines had trouble reaching that in 2006. Traditionally POWER has always had large amounts of CPU cache which is one reason why they're so expensive, only recently has Intel started to catch up with aging memory and CPU cache limitations.

Due to the age of the POWER processor, it doesn't even support AIX 6.1.



--> System Firmware CLT05208 (09/19/2005)

Due to IBM's licensing agreements I am not entitled to distribute the firmware update as it's licensed code. Therefore the above link redirects to IBM's Legacy Firmware page where it can be downloaded. In the event the firmware becomes unavailable, I will consider mirroring it.

--> 3Dconnexion Xdriver AIX 4 (4.64 03/04/2005)

Note: it seems that the 3DxWare driver should support the SpaceBall and SpaceMouse, along with offering new support for the SpacePilot and SpaceExplorer on AIX. However if that's not the case the older Xdriver can be used.

Note: you must purchase a license from 4Front Technologies to activate OSS/AIX (while it's released as open source the old UNIX versions are not).


OS Support


AIX 7.2 Not Supported
AIX 7.1 Not Supported
AIX 6.1 Not Supported
AIX 5.3 Supported
AIX 5.2 Supported
AIX 5.1 Supported
AIX 4.3.3 Supported
AIX 4.2.1 Probably Not Supported
AIX 3.2.5 Not Supported

This would be a good choice if you need to run AIX 4.3.3 for some reason.


Didn't find any information documented on this, will investigate maybe at some point later. I don't own one of these systems so it's a low priority. Due to the rather low AIX support, the POWER Linux distros are likely to be very old too.
