Sun Ultra 5 and T2/Linux

The Sun Ultra 5 series was a UltraSPARC-based computer workstation developed and sold by Sun Microsystems as entry level, low-cost SPARC workstation and was largely based on cheap components from the PC world to reduce cost (IDE disks, ATI Mach64 graphic, ...).

The built-in IDE and graphic chip (Mach 64) are both a little low-performance. Adding an additional VGA and SCSI cards can bump performance, however if the system should boot from a SCSI disk an Symbios Logic card with Open Firmware Forth code needs to be added. Other cards, such as Adaptec & Co do work in Linux, but an IDE disk needs to be used to load the OS in that case.
