I know that for example:
lshw - Shows all the info for all hardware.
lsusb - Shows all connected USB devices.
lspci - Shows all PCI connected devices including AGP, PCIex and any other related.
cat /proc/meminfo - Shows information about the memory.
cat /proc/cpuinfo - Show information about the CPU.
hdparm -Ii /dev/sda - Shows information about the HDD.
But what about the motherboard.
lshw is too generic. Is there a specific command for the motherboard. To show what the motherboard is capable of, name, version, slots, etc.. Information specific to the motherboard.
