Complete information concerning supported peripherals can be found at Linux Hardware Compatibility HOWTO. This section merely outlines the basics. Nearly all x86-based (IA-32) processors still in use in personal computers are supported, including all varieties of Intel's "Pentium" series. This also includes 32-bit AMD and VIA (former Cyrix) processors, and processors like the Athlon XP and Intel P4 Xeon. However, &debian; GNU/Linux &releasename; will not run on 386 or earlier processors. Despite the architecture name "i386", support for actual 80386 processors (and their clones) was dropped with the Sarge (r3.1) release of &debian;. (No version of Linux has ever supported the 286 or earlier chips in the series.) All i486 and later processors are still supported. If your system has a 64-bit processor from the AMD64 or Intel 64 families, you will probably want to use the installer for the amd64 architecture instead of the installer for the (32-bit) i386 architecture. The system bus is the part of the motherboard which allows the CPU to communicate with peripherals such as storage devices. Your computer must use the ISA, EISA, PCI, PCIe, PCI-X, or VESA Local Bus (VLB, sometimes called the VL bus). Essentially all personal computers sold in recent years use one of these.
