BUGS
More often than not, information contained in the DMI tables is inaccu‐
rate, incomplete or simply wrong.
Assim, os próprios autores avisam o usuário que as informações retornadas podem ser uma porcaria.
Outro programa que é útil para obter informações sobre o BIOS (embora não a data de lançamento) é biosdecode
, que costumava fazer parte de dmidecode
, mas agora foi separado dele. Exemplo de saída:
# biosdecode 2.12
