Abstract

Esta solicitud proporciona un método y aparato de arranque de sistema, un dispositivo electrónico y un medio de almacenamiento. El método incluye: establecer una relación de mapeo entre espacio de direcciones de un primer dispositivo de almacenamiento y espacio de direcciones de un segundo dispositivo de almacenamiento si se detecta que los datos son incapaces de escribirse normalmente en el primer dispositivo de almacenamiento o se recibe una instrucción preestablecida de un usuario; recibir una solicitud de lectura/escritura enviada al primer dispositivo de almacenamiento, donde la solicitud de lectura/escritura se utiliza para obtener o almacenar los datos necesarios durante el arranque de sistema; si la solicitud de lectura/escritura es una solicitud de escritura para el primer dispositivo de almacenamiento, escribir datos a una segunda dirección en el segundo dispositivo de almacenamiento con base en una primera dirección en el primer dispositivo de almacenamiento en la solicitud de escritura y la relación de mapeo; o si la solicitud de lectura/escritura es una solicitud de lectura para el primer dispositivo de almacenamiento, determinar si los datos se han escrito en una cuarta dirección correspondiente a una tercera dirección en la solicitud de lectura; y leer datos desde la cuarta dirección si los datos se han escrito en la cuarta dirección; o leer datos desde la tercera dirección si no se han escrito datos en la cuarta dirección. Esta aplicación puede garantizar arranque normal del sistema.
