Abstract

"SISTEMA PARA HABILITAR SELETIVAMENTE MODOS DE OPERAçãO DE UM DISPOSITIVO". Trata-se de um sistema para habilitar seletivamente modos de operação de um dispositivo. O sistema inclui um método para habilitar seletivamente os modos de operação de um dispositivo durante a inicialização do dispositivo, em que os modos de operação compreendem um modo privilegiado e um modo nao privilegiado. O método inclui determinar, durante a inicialização do dispositivo, se o dispositivo vai operar no modo privilegiado ou tanto no modo privilegiado quanto no modo não privilegiado e habilitar o modo privilegiado se for determinado que o dispositivo esteja para operar apenas no modo privilegiado. O método inclui também habilitar tanto o modo privilegiado quanto o modo não privilegiado se for determinado que o dispositivo esteja para operar tanto no modo privilegiado quanto no modo não privilegiado.
