AXi

Introduction

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:

• UW-SCSI on-board (instead of IDE)
• no sound on-board
• no framebuffer on-board
• additional PS/2 connectors for keyboard/mouse
• six (instead of four) PCI slots
• eight memory slots (instead of four), though the maximum memory configuration still is only 1GB - the eight slots are separated in two groups of four, which support different types of memory.

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
