cpuid dumps detailed information about the CPU(s) gathered from the CPUID instruction, and also determines the exact model of CPU(s).

hwinfo is a program developed by OpenSUSE. 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.

Dmidecode reports information about your system's hardware as described in your system BIOS according to the SMBIOS/DMI standard. This information typically includes system manufacturer, model name, serial number, BIOS version, asset tag as well as a lot of other details of varying level of interest and reliability depending on the manufacturer. This will often include usage status for the CPU sockets, expansion slots (e.g. AGP, PCI, ISA) and memory module slots, and the list of I/O ports (e.g. serial, parallel, USB).

read-edid is a pair of tools (originally by John Fremlin) for reading the EDID from a monitor. It should work with most monitors made since 1996 (except for newer ones with 256-byte EDID's - WiP), assuming the video card supports the standard read commands (most do).read-edid is a set of two tools - get-edid, which gets the raw edid information from the monitor, and parse-edid, which turns the raw binary information into an XF86Config-compatible monitor section.

vbetool is a small application that executes code from the BIOS of your video card. This is mostly useful for reinitialising the hardware, for instance after ACPI suspend/resuming.
