The AXi board is an UltraSPARC based motherboard in standard ATX format. It is very similar to those of a U5/U10, with the following exceptions:

The AXi board can be used in any PC-ATX case and has been used in many U10-clones like the Tatung COMPstation U10.

Tested Configurations

Aurora Version Configuration Remarks Reporter
1.0 Tatung COMPstation U10, 400MHz UltraSPARC IIi, Raptor GFX-8P (PGX32) frame buffer, 640MB RAM The Raptor is not 100% supported by the installer and can also cause trouble when switching between X and console. Also, you need to use XFree86 3.3.6 drivers, as XFree86 4.x does not (yet?) fully support this card. The 400MHz CPU came from an Ultra 5/400 and works well with this machine, even though it is not officially supported. Emgaron
1.92 Tatung COMPstation U10, 440MHz UltraSPARC IIi, Creator 3D Series 3 frame buffer, 1GB RAM Works! Emgaron
2.0 [Marathon 2U rackmount]?, 440MHz UltraSPARC IIi, ATI Rage pci card, 256MB RAM Works! (i use it headless) Dgilmore
