The Ultra 5 (A21) is a fairly common workstation class sun4u. This machine has the exact same mainboard as the Ultra 10. The only difference between the two machines is the case (U5: Desktop, U10: Midi-tower) and the supported CPU and memory configurations. When compared to the U10, the smaller case causes a few restrictions with regard to what hardware can be used:
Like the U10, it differs from earlier Ultras in that it is designed to use more generic PC style parts such as IDE and PCI instead of SCSI and SBUS.
The small mystery slot on the front of the case is for a PCMCIA addon, but these are quite rare.
Linux Notes: This machine works pretty well under Linux, but as a result of its low-grade IDE controller, DMA almost never works properly, and you'll almost definitely want to disable it for stability.
The Aurora Project does not currently own an Ultra 5. But we own several Ultra 10s, and since they're so similar, that is usually good enough for government work.
Tested Configurations
| Aurora Version | Configuration | Remarks | Reporter |
| 1.0 | 400MHz UltraSPARC-IIi, Raptor GFX-8P framebuffer, 256MB RAM | Worked nicely as a workstation, but you need to use the XFree 3.3.6 drivers for the Raptor. Also, the installer does not fully support the Raptor (colours go all funny) | Emgaron |
| 1.0, 1.92 | 440MHz UltraSPARC-IIi, ATI 3D Rage Pro 215GP(?) video, 384MB RAM | Never really used the video (headless over serial). Otherwise works fine. (Unsupported CPU is nice.) | Jima |
