Debian on &arch-title; supports the following platforms: SGI IP22: this platform includes the SGI machines Indy, Indigo 2 and Challenge S. Since these machines are very similar, whenever this document refers to the SGI Indy, the Indigo 2 and Challenge S are meant as well. SGI IP32: this platform is generally known as SGI O2. Broadcom BCM91250A (SWARM): this is an ATX form factor evaluation board from Broadcom based on the dual-core SB1 1250 CPU. Broadcom BCM91480B (BigSur): this is an ATX form factor evaluation board from Broadcom based on the quad-core SB1A 1480 CPU. Complete information regarding supported mips/mipsel machines can be found at the Linux-MIPS homepage. In the following, only the systems supported by the Debian installer will be covered. If you are looking for support for other subarchitectures, please contact the debian-&arch-listname; mailing list. On SGI IP22, SGI Indy, Indigo 2 and Challenge S with R4000, R4400, R4600 and R5000 processors are supported by the Debian installation system on big endian MIPS. On SGI IP32, currently only systems based on the R5000 are supported. The Broadcom BCM91250A evaluation board comes with an SB1 1250 chip with two cores which are supported in SMP mode by this installer. Similarly, the BCM91480B evaluation board contains an SB1A 1480 chip with four cores which are supported in SMP mode. Some MIPS machines can be operated in both big and little endian mode. For little endian MIPS, please read the documentation for the mipsel architecture.
