Looking for a complete list of all the devices, IRQs, and memory addresses in use by your machine? Type


into a Terminal window and you’ll learn more than you probably wanted to know. This list is essentially the same info you can get from the Devices panel, but can be scanned and searched. To save the info to a text file, use

listdev > ~/device_info.txt

Another way to get info on your PCI bus from the terminal is to type poke. At the poke prompt, type help to see a list of options. Type pci to get a listing of all your PCI settings. It probably wouldn’t be a good idea to use any of the poke options that write to memory unless you really know what you’re doing!

Type quit to exit poke and return to your bash prompt.
