       hwinfo - probe for hardware


       hwinfo [ OPTIONS ]


       hwinfo is used to probe for the hardware present in the system. It can be used to generate
       a system overview log which can be later used for support.


       Note that running hwinfo without any  options  is  roughly  equivalent  to  'hwinfo  --all

              This  option  can  be  given more than once.  Probe for a particular HARDWARE_ITEM.
              Available hardware items are:

              all, arch, bios, block, bluetooth, braille, bridge, camera, cdrom,  chipcard,  cpu,
              disk,  dsl, dvb, fingerprint, floppy, framebuffer, gfxcard, hub, ide, isapnp, isdn,
              joystick, keyboard, memory, mmc-ctrl,  modem,  monitor,  mouse,  netcard,  network,
              partition,  pci,  pcmcia,  pcmcia-ctrl, pppoe, printer, redasd, reallyall, scanner,
              scsi, smp, sound, storage-ctrl, sys, tape, tv, uml, usb, usb-ctrl, vbe, wlan,  xen,

              Note that if this option is missing, no hardware probing will be done!

              Show only a summary. Use this option in addition to a hardware probing option.

              Normally hwinfo does not report RAID devices. Add this option to see them.

       --only DEVNAME
              This option can be given more than once. If you add this option only entries in the
              device list matching DEVNAME will be shown.  Note that you  also  have  to  specify
              --<HARDWARE_ITEM> to trigger any device probing.

       --save-config SPEC
              Store  config for a particular device below /var/lib/hardware. SPEC can be a device
              name, an UDI, or 'all'. This option must be given in addition to a hardware probing

       --show-config UDI
              Show saved config data for a particular device.

       --map  If  disk names have changed (e.g. after a kernel update) this prints a list of disk
              name mappings. Note that you must have used --save-config at some point before  for
              this can work.

       --debug N
              Set debug level to N. The debug info is shown only in the log file.  If you specify
              a log file, the debug level is implicitly set to a reasonable value (N is a bitmask
              of individual flags).

              Increase verbosity. Only together with --map.

       --log FILE
              Write  log info to FILE.  Don't forget to also specify --<HARDWARE_ITEM> to trigger
              any device probing.

       --dump-db N
              Dump  hardware  data  base.  N  is  either  0  for  the  external  data   base   in
              /var/lib/hardware, or 1 for the internal data base.

              Print libhd version.

       --help Print usage.


       hwprobe  can  hold  a  comma-separated  list of probing flags preceded by '+' or '-' to be
       turned on or off. To get a complete list of supported flags, run 'hwinfo -all' (note:  not
       '--all') and look at the top of the output.

       hwinfo also looks at /proc/cmdline for a hwprobe option.


       - show all disks
              hwinfo --disk

       - just an overview
              hwinfo --short --block

       - show a particular disk
              hwinfo --disk --only /dev/sdb

       - save disk config state
              hwinfo --disk --save-config=all

       - try 4 graphics card ports for monitor data (default: 3)
              hwprobe=bios.ddc.ports=4 hwinfo --monitor

       - monitor detection runs the Video BIOS to get the monitor data; dump a complete BIOS code
       execution trace to the log
              hwprobe=bios.ddc.ports=1,x86emu=trace:dump:trace.only=0:dump.only=0          hwinfo
              --monitor --log=foo


              External  hardware  data  base (in readable text form). Try the --dump-db option to
              see the format.

              Directory where persistent config data are stored (see --save-config option).


       Not all hardware can be detected.
