Additional Packages

# Some addition tools to output Hardware information.

General Hardware Output

# lshw can produce a general detailed overview of devices in your system.
# It'll output information about cpu, memory, disks, USB, network etc.
$ sudo pacman -S lshw

# For a short overview
$ lshw -short

Another - even more detailed - general hardware output

# Another tool is hwinfo which should produce a even more detailed output
$ pacman -S hwinfo

# A short overview
$ hwinfo --short

Hardware information served straight from the BIOS!

# dmidecode reads BIOS based information.
# It can, a.a, not only tell you how much ram you have installed-
# But also what the maximum amount of ram your system will accept.
$ pacman -S dmidecode

# CPU
$ dmidecode -t processor

# Memory
$ dmidecode -t memory

# BIOS details (etc etc)
$ dmidecode -t bios
