1. hardware identification system Discover is a hardware identification system based on the libdiscover1 library. Discover provides a flexible interface that programs can use to report a wide range of information about the hardware that is installed on a Linux system. In addition to reporting information, discover includes support for doing hardware detection at boot time. Detection occurs in two stages: The first stage, which runs from an initial ramdisk (initrd), loads just the drivers needed to mount the root file system, and the second stage loads the rest (ethernet cards, sound cards, etc.).
