2.1. Supported Hardware

Debian does not impose hardware requirements beyond the requirements of the Linux kernel and the GNU tool-sets. Therefore, any architecture or platform to which the Linux kernel, libc, gcc, etc. have been ported, and for which a Debian port exists, can run Debian. Please refer to the Ports pages at http://www.debian.org/ports/mipsel/ for more details on Mipsel architecture systems which have been tested with Debian.

Rather than attempting to describe all the different hardware configurations which are supported for Mipsel, this section contains general information and pointers to where additional information can be found.

2.1.1. Supported Architectures

Debian 5.0 supports eleven major architectures and several variations of each architecture known as “flavors”.

This document covers installation for the Mipsel architecture. If you are looking for information on any of the other Debian-supported architectures take a look at the Debian-Ports pages.

2.1.2. CPU, Main Boards, and Video Support

Debian on Mipsel supports the following platforms:

  • Cobalt Microserver: only MIPS based Cobalt machines are covered here. This includes the Cobalt Qube 2700 (Qube1), RaQ, Qube2 and RaQ2, and the Gateway Microserver.

  • MIPS Malta: this platform is emulated by QEMU and is therefore a nice way to test and run Debian on MIPS if you don't have the hardware.

  • 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-mips mailing list. CPU/Machine types

All MIPS based Cobalt machines 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. Supported console options

Both Cobalt and Broadcom BCM91250A/BCM91480B use 115200 bps.

2.1.3. Graphics Card Support

Debian's support for graphical interfaces is determined by the underlying support found in X.Org's X11 system. Most AGP, PCI and PCIe video cards work under X.Org. Details on supported graphics buses, cards, monitors, and pointing devices can be found at http://xorg.freedesktop.org/. Debian 5.0 ships with X.Org version 7.3.

The Broadcom BCM91250A and BCM91480B evaluation boards have standard 3.3v PCI slots and support VGA emulation or Linux framebuffer on a selected range of graphics cards. A compatibility listing for Broadcom evaluation boards is available.

2.1.4. Network Connectivity Hardware

Almost any network interface card (NIC) supported by the Linux kernel should also be supported by the installation system; modular drivers should normally be loaded automatically.

2.1.5. Peripherals and Other Hardware

Linux supports a large variety of hardware devices such as mice, printers, scanners, PCMCIA and USB devices. However, most of these devices are not required while installing the system.

The Broadcom BCM91250A evaluation board offers standard 3.3v 32 bit and 64 bit PCI slots as well as USB connectors. The Broadcom BCM91480B evaluation board features four 64 bit PCI slots. The Cobalt RaQ has no support for additional devices but the Qube has one PCI slot.
