lshw -disable dmi
Don’t use DMI to detect hardware.
a small tool to extract detailed information on the hardware
configuration of the machine. It can report exact memory
configuration, firmware version, mainboard configuration,
CPU version and speed, cache configuration, bus speed, etc.
on DMI-capable x86 or IA-64 systems and on some PowerPC
machines (PowerMac G4 is known to work).
supports DMI (x86 and IA-64 only), OpenFirmware device tree
