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.

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. |
