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 for more details on &arch-title; architecture systems which have been tested with Debian. Rather than attempting to describe all the different hardware configurations which are supported for &arch-title;, this section contains general information and pointers to where additional information can be found. Debian &release; supports eleven major architectures and several variations of each architecture known as flavors.

If you are looking for information on any of the other Debian-supported architectures take a look at the Debian-Ports pages. This is the first official release of &debian; for the &arch-title; architecture. We feel that it has proven itself sufficiently to be released. However, because it has not had the exposure (and hence testing by users) that some other architectures have had, you may encounter a few bugs. Use our Bug Tracking System to report any problems; make sure to mention the fact that the bug is on the &arch-title; platform. It can be necessary to use the debian-&arch-listname; mailing list as well. &supported-alpha.xml; &supported-arm.xml; &supported-hppa.xml; &supported-i386.xml; &supported-ia64.xml; &supported-m68k.xml; &supported-mips.xml; &supported-mipsel.xml; &supported-powerpc.xml; &supported-s390.xml; &supported-sparc.xml; You should be using a VGA-compatible display interface for the console terminal. Nearly every modern display card is compatible with VGA. Ancient standards such CGA, MDA, or HGA should also work, assuming you do not require X11 support. Note that X11 is not used during the installation process described in this document. 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 . Debian &release; ships with X.Org version &x11ver;. The X.Org X11 window system is only supported on the SGI Indy and the O2. 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. The X.Org X11 window system is supported on some DECstation models. 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. Laptops are also supported. Laptops are often specialized or contain proprietary hardware. To see if your particular laptop works well with GNU/Linux, see the Linux Laptop pages Multi-processor support — also called symmetric multi-processing or SMP — is available for this architecture. The standard Debian &release; kernel image was compiled with SMP support. This should not prevent installation, since the SMP kernel should boot on non-SMP systems; the kernel will simply cause a bit more overhead. In order to optimize the kernel for single CPU systems, you'll have to replace the standard Debian kernel. You can find a discussion of how to do this in . At this time (kernel version &kernelversion;) the way you disable SMP is to deselect &smp-config-option; in the &smp-config-section; section of the kernel config. Multi-processor support — also called symmetric multi-processing or SMP — is available for this architecture. However, the standard Debian &release; kernel image does not support SMP. This should not prevent installation, since the standard, non-SMP kernel should boot on SMP systems; the kernel will simply use the first CPU. In order to take advantage of multiple processors, you'll have to replace the standard Debian kernel. You can find a discussion of how to do this in . At this time (kernel version &kernelversion;) the way you enable SMP is to select &smp-config-option; in the &smp-config-section; section of the kernel config. Multi-processor support — also called symmetric multi-processing or SMP — is available for this architecture, and is supported by a precompiled Debian kernel image. Depending on your install media, this SMP-capable kernel may or may not be installed by default. This should not prevent installation, since the standard, non-SMP kernel should boot on SMP systems; the kernel will simply use the first CPU. In order to take advantage of multiple processors, you should check to see if a kernel package that supports SMP is installed, and if not, choose an appropriate kernel package. You can also build your own customized kernel to support SMP. You can find a discussion of how to do this in . At this time (kernel version &kernelversion;) the way you enable SMP is to select &smp-config-option; in the &smp-config-section; section of the kernel config.
