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. USB hardware generally works fine, only some USB keyboards may require additional configuration (see ). Again, see the Linux Hardware Compatibility HOWTO to determine whether your specific hardware is supported by Linux. Package installations from XPRAM and tape are not supported by this system. All packages that you want to install need to be available on a DASD or over the network using NFS, HTTP or FTP. 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.
