Description of the invention (6) ------- The USB port 2 of the embodiment 9 is used to connect the peripheral devices outside the notebook computer 2 to the peripheral device of the embodiment means Notebook 1) Establish + clothing α + 1 ~ 1% sexual connection relationship with it, and make USB port 29 provide plug-in gp field through usm controller 28, using C Plug and p 1 ay) function, make the The notebook computer 2 can be connected, configured, used and removed at any time. As the above chips, control cry-memory and USB port are all components familiar to computer technicians, ^ therefore '^ Therefore, the function and internal structure will not be further detailed here. The part related to this invention is demonstrated. “” As shown in FIG. 3, it is a schematic diagram showing the software architecture required for the data access system of the present invention. The software architecture required in this embodiment is built in the BIOS R0M23 of the reference notebook computer 2 and In the NVRAM27, the BIOS program stored in the BIOS ROM23 has a section of the USB port setting program 23〇, '= The USB port setting program 2 3 0 is provided for the user to set the work of the USB port 2 9 of the notebook computer 2 Mode, the working mode of the USB port 29 in this embodiment includes performing a general USB port connection service and turning on the hard disk 2 5 of the notebook computer 2 for external access services. Here, the so-called general USB port connection service is Provides the function of piug and play of peripheral devices connected to the USB port 29, and the so-called external access service of turning on the hard disk 25 of the notebook computer 2 is provided with the USB port 2 9 Connected peripheral devices to access the data stored in the notebook 2 hard disk 2 5 _ Therefore after the user runs the USB port setting program 2 3 0 and complete the USB port working mode setting 'notebook computer 2 NVRAM access controller 26 is about to be used The USB port working mode setting value 27 set by the user is stored in the NVRAM 27. In this way, when the notebook computer 2 is booted smoothly and detected by the USB controller 28

200538941 V. Description of the invention (7) — '~ " * When the USB port 29 is inserted, the nvram26 access controller 26 reads the USB port working mode setting value 27 stored in NVRAM26 to make the notebook type The USB port working mode setting value read by 2 computers of Kang 2 is to control the working mode of the USB port. For example, if the ㈣ 璋 working mode setting value 2 stored in the notebook computer 2 is 70, it means that the notebook computer 2 is opened. The external storage = service of the hard disk 25 will enable the notebook type connected to the USB port 2 9 through the connection interface 3 such as a USB transmission line to be read directly! In contrast, if the USB port working mode setting value 2 70 stored in the notebook computer 2 is a general USB port connection service, the notebook computer connected to the USB port 29 through the connection ^ face 3 cannot be used 丨Read the data in the hard disk 25, that is, the 25 data stored in the laptop 2 == can only be read locally by the laptop 2 and cannot be read by the device. The user executed the USB 珲 setting program 23〇, the user set the USB port working mode In addition, it also provides the local hardware, password setting processing, and after the password setting is completed, the note / access NVRAM access controller 26 stores the code 271 of the local computer 2 set by the user in NVRAM27. In this way, when the notebook computer is accessed and the USB controller 28 detects that the USB port 2 9 is inserted, the USB port works smoothly. The setting value of 27 is to turn on the notebook computer and determine the external When accessing the service, it is necessary for the user to access the password on the hard disk of the notebook computer 2 5 Local hard disk access password. If the user enters the storage ^ 2 in turn, the local hard disk stored in the NVRAM 27 is rounded. The disc access password 271 is the same, that is, = a notebook type connected to the USB port 2 9 through the connection interface 3 with the saver ^ I make the computer 1 directly

200538941 V. Description of the invention (8) Read the data of the hard disk 25 in the notebook computer 2, otherwise, even if the USB port working mode setting value 2 7 0 is to open the external storage service of the hard disk 25 of the notebook computer 2 However, when the local hard disk access password that the user turns in is different from the local hard disk access password 271 stored in the NVRAM 27, the notes connected to the USB port 29 of the notebook computer 2 cannot be made. PC 丨 Access Hard Disk 2 5 of Notebook 2 Therefore, by setting and comparing the local hard disk access password, you can ensure the security of hard disk data access. Then, "the one shown in Fig. 4 is a schematic flow chart of the data access method of the present invention" The notebook computer described in the flowchart of this embodiment is still a notebook computer not shown in the foregoing first and second drawings (1 and 2) Explain as an example. As shown in FIG. 4, step S1 is performed immediately after the notebook computer 2 is successfully turned on, so that the notebook computer 2 determines whether u SB port 2 9 is electrically connected to the notebook computer 1 'If yes, proceed to step S2 If it is not connected to the notebook computer 1, the determination step of step S1 is continued. In this step S2, the NVRAM access controller 26 of the notebook computer 2 is caused to read the USB port operating wedge setting value 270 from the NVRAM 27, and then proceeds to step S3. In step S3, 'let the notebook computer 2 judge whether the read USB port working mode setting value 2 7 0 is-the connection service setting of the general USB port, if it is, go to step S4; if not, go to Step S5. In step S4, the notebook computer 2 causes the USB controller 28 to control the USB port 29 to be used as a general USB port connection function, that is, the notebook computer 1 electrically connected to the USB port 29 is prohibited from reading. Hard drive 2 5 data for notebook computer 2.

Description of the invention (9) One to the other; 忒 In step S5, the notebook computer 2 judges that the read USB port working setting value 2 70 is on After the hard disk 25 of the notebook computer 2 is set to an external access service setting, the notebook computer 2 causes the user to enter the local hard disk access password of the laptop 2 and then proceeds to step s6. In step S6, the notebook computer 2 reads the pre-stored hard disk access password 271 from the NVRAM 27, and compares it with the local hard input entered by the user to compare it with the password to determine whether the two are the same ( That is, it is judged whether = the input password of the local hard disk is correct.) # If the two are the same, go to step S7. If the two are different, continue to perform the judgment of step §6 in step S7. The usw 29 of the notebook computer 2 is electrically connected to the computer 1 through a connection interface 3 such as a leg transmission line to access the data in the notebook 2 hard disk 25. It is known that the two data storage systems and methods of the present invention will allow two computers (丨 and 2) to access each other ’s hard disks (丨 materials) to achieve the purpose of data sharing. In addition, When the invention's data storage system and method are applied to, for example, a notebook computer or a personal digital assistant, a portable electronic device, the portable electronic storage device can be used as a kind of mobile data storage. Device, so as to use other electronic devices for data access. The above-mentioned embodiment only exemplarily illustrates the principle of the present invention and its function: it is used to limit the present invention, for example, the present invention is applied in addition to the above embodiments; Type computer (Bu 2), can also be applied to two different electronic two, such as a notebook computer to a desktop computer, desktop computer pair;
