(4) description of drawings
Fig. 1 is the circuit block diagram of the use IC storage card starting computer system of a preferred embodiment of the present invention.
(5) embodiment
The different IC storage card of many kinds is arranged at present on the market, safe digital card (SecureDigital for example, SD), memory stick (Memory Stick, MS), multimedia storage card (Multi Media Card, MMC) or the like, and the part all by universal serial bus (Universal Serial Bus, USB) access is carried out at the interface, its major function is all data storing.And the present invention utilizes the IC storage card, by low pin count interface (Low Pin Count, LPC) or peripheral part linkage interface (Peripheral ComponentInterconnect, PCI) interface of direct access computer ROM-BIOS storer (all can) be used as the backup of computer ROM-BIOS storer (BIOS Memory), with the problem that prevents from computer ROM-BIOS storer because of computer virus or artificial destruction and cause to start shooting.
See also Fig. 1, it is the circuit block diagram of the use storage card starting computer system of a preferred embodiment of the present invention, and this computer system comprises a motherboard 12, a power supply unit 11, a control circuit 13, reaches a storage card reading device 15.Wherein, this motherboard 12 is provided with a chipset 121 and a ROM-BIOS storer 122, this chipset 121 is to be electrically connected with this control circuit 13 by LPC or PCI interface with this ROM-BIOS storer 122, and this control circuit 13 also is electrically connected on this power supply unit 11 and this storage card reading device 15 respectively.This power supply unit 11 can provide a standby power to this motherboard 12 and this control circuit 13, and this storage card reading device 15 is then in order to read an IC storage card 14.
This above-mentioned IC storage card 14 stores a ROM-BIOS, when this ROM-BIOS storer 122 of this computer system causes starting shooting because of computer virus or artificial destruction, the user can insert this IC storage card 14 this storage card reading device 15 this moment, and press a specific keys (not shown) on this computer system panel, select signal (Boot-up Select) to start a start.After the user presses this specific keys, this start selects signal to be sent to this control circuit 13 immediately, this control circuit 13 receives this start and selects can send out a disable signal (Disable) this ROM-BIOS storer 122 with this computer system of forbidden energy earlier behind the signal, read this ROM-BIOS that is stored on this IC storage card 14 then, to open this computer system of beginning.
The other function of the present invention is for storing a password (do not had the ROM-BIOS storer on this motherboard this moment or forever by forbidden energy) in the ROM-BIOS storer, when the IC storage card is inserted the storage card reading device, control circuit can read the password in the IC storage card earlier, after comparing correctly, just open computer system, to reach the function of system secrecy.Its step following (please cooperate and consult Fig. 1):
At first, provide an IC storage card 14 that stores one second password and a ROM-BIOS.Then, this IC storage card 14 is inserted this storage card reading device 15.Then, this control circuit 13 can read this second password that is stored on this IC storage card 14, and this second password and one first password that is stored on this control circuit 13 compared, when this second password equals this first password (the password comparison is correct), this control circuit 13 just can read this ROM-BIOS that is stored on this IC storage card 14, and the PSON# that sent out by this chipset 121 this moment will transfer low to, and then start this power supply unit 11, power with motherboard 12, realize that the beginning of opening of this computer system operates this computer system.
This above-mentioned control circuit 13 is that the PSON# of will be sent out by this chipset 121 stops, and only when this second password equaled this first password, PSON# just can transfer low to, and this computer system also just can be finished and open the beginning running.And if this second password is when being not equal to this first password (the password comparison is incorrect), PSON# then be high, makes this power supply unit 11 to be activated, so this computer system also can't open the beginning and operates.
This IC storage card 14 used in the present invention also can store an operating system (for example DOS, WINDOWS etc.), therefore in this computer system finish open the beginning running after, can read this operating system that is stored on this IC storage card 14 at once, make this IC storage card 14 promptly convenient as same Portable operating system.
In sum, utilization of the present invention is stored in the ROM-BIOS starting computer system of IC storage card, does not need to increase the space of the motherboard of computer system, and the remaining space of IC storage card also can be used as data storing.In addition,, go back maintain secrecy function with the Portable operating system of feasible system, effectively improve the disappearance of known techniques, therefore have industrial value, and then reach development purpose of the present invention by password that is stored in the IC storage card and operating system.
