The RM 200 is a MIPS based workstation originally developed by Pyramid which got bought out by Siemens-Nixdorf. There are several different versions indicated by a letter; Linux only supports the C version which has EISA and PCI slots and which started shipping in 1996 in two configurations, one little endian for running Windows NT and a big endian for running Siemens's UNIX flavour du jour SINIX.

With a special floppy disk containing firmware it is possibly to reconfigure RM 200 systems from little to big endian and vice versa. Since unfortunately the firmware is copyrighted and Linux/MIPS project neither has a copy of the big endian firmware disk nor the permission to distribute the firmware or any other source.

Due to lack of a system in a big endian system for development only the little endian configuration is supported under Linux. No Linux distribution supports the RM 200 out of the box so any installation will require some Linux skills and an additional Linux system to boot the RM 200 from via network. Linux support for the RM200 is available since kernel version 2.1 (requires out of tree patches). Due to a hardware problem for which for a long time no workaround was known Linux 2.2 and 2.3 were unsupported on RM 200; late 2.5 versions fixes these issues. Latest successfully tested version is 2.6.10-rc1 and is considered stable.
