Multifunction semiconductor storage device and a method for booting-up computer host

Abstract

A semiconductor storage device connected to the host system through the general purpose interface, including a semiconductor storage media module ( 1 ) and a controller module ( 2 ), in which the controller module ( 2 ) consists of a general purpose interface control module ( 21 ), a microprocessor and control module ( 22 ). Various device class protocols can be realized at the interface application level of the semiconductor storage device, which makes it possible to simulate and realize the storage functions of various storage disks. One or a plurality of storage spaces are opened up in the semiconductor storage media and one or a plurality of storage disks are supported by the same device; furthermore, the device supports hot plug and play and it is removable.

1 . A method for booting up computer using the multifunction. semiconductor storage device, comprising the steps of: 
 a. storing the boot program of the operating system and operating system programs into the multifunction semiconductor storage device;    b. connecting the multifunction semiconductor storage device with the computer host system through the general-purpose interface;    c. identifying the general purpose interface, and controlling and reading/writing the multifunction semiconductor storage device based on BIOS after powered up the computer host system; and    d. loading the boot program of the operating system and operating system programs stored in the multifunction semiconductor storage device to computer host system for achieving computer boot-up.
