Abstract

UN SISTEMA DE ORDENADOR Y EL METODO PARA OPERAR UN SISTEMA DE ORDENADOR CAPAZ DE MARCHAR EN MODOS DE DIRECCION PROTEGIDA Y REAL INCOMPATIBLE MUTUAMENTE, EN QUE LOS PROGRAMAS ESCRITOS POR UN MODO PUEDEN SER USADOS EN EL OTRO MODO SIN MODIFICACION. EL BIOS MONTA DOS AREAS DE DATOS COMUNES DIFERENTES PARA LOS DOS MODOS, CAD UNO INCLUYE INDICADORES DE BLOQUEO DEL DISPOSITIVO, INDICADORES DE MESA DE TRANSFERENCIA DE FUNCIONES INDICADORES DE DATOS E INDICADORES DE FUNCIONES. EL AREA DE DATOS COMUNES PARA EL MODO REAL ESTA MONTADO PRIMERO. PARA MANTENER LOS INDICADORES PARA EL AREA DE DATOS COMUNES DEL MODO PROTEGIDO, EL VALOR COMPENSADO DEL AREA DEL MODO REAL ES COPIADA DIRECTAMENTE, Y ENTONCES EL VALOR SELECTOR ES INSERTADO A CUYAS DIRECCIONES FISICAS CORRESPONDE A LOS SEGMENTOS DE LOS INDICADORES CORRESPONDIENTES EN EL AREA DE MODO REAL. EL VALOR SELECTOR SE DERIVA DE UNA MESA DESCRIPTIVA DE SEGMENTOS.
