# 42.4. Hardware

If you are having trouble configuring your hardware or just want to know what hardware is in your system, you can use the Hardware Browser application to display the hardware that can be probed. To start the program from the desktop, select Main Menu Button => System Tools => Hardware Browser or type `hwbrowser` at a shell prompt. As shown in Figure 42-3, it displays your CD-ROM devices, floppy disks, hard drives and their partitions, network devices, pointing devices, system devices, and video cards. Click on the category name in the left menu, and the information will be displayed.

You can also use the `lspci` command to list all PCI devices. Use the command `lspci -v` for more verbose information or `lspci -vv` for very verbose output.

For example, `lspci` can be used to determine the manufacturer, model, and memory size of a system's video card:

    01:00.0 VGA compatible controller: Matrox Graphics, Inc. MGA G400 AGP (rev 04) \
    (prog-if 00 [VGA])
    Subsystem: Matrox Graphics, Inc. Millennium G400 Dual Head Max
    Flags: medium devsel, IRQ 16
    Memory at f4000000 (32-bit, prefetchable) [size=32M]
    Memory at fcffc000 (32-bit, non-prefetchable) [size=16K]
    Memory at fc000000 (32-bit, non-prefetchable) [size=8M]
    Expansion ROM at 80000000 [disabled] [size=64K]
    Capabilities: [dc] Power Management version 2
    Capabilities: [f0] AGP version 2.0

The `lspci` is also useful to determine the network card in your system if you do not know the manufacturer or model number.
