Abstract
The utility model provides a kind of firmware upgrade protective device, it includes：One firmware holder, storage firmware in it；Switch element, it electrically associates the firmware holder, operates switch element locking or unlocks the firmware holder.The firmware upgrade protective device of the utility model can pin the firmware holder that associated firmware updates by the switch element, make machine protected, it is impossible to arbitrarily to update firmware, the artificial operation of more steps, makes machine safer.
Description
【Technical field】
The utility model is a firmware upgrade protective device.
【Background technology】
Firmware（firmware）Refer to the equipment " driver " preserved inside equipment, pass through firmware, operating system ability
Device drives according to standard realize that the run action of particular machine, such as CD-ROM drive, CD writer etc. have internal firmware.Firmware is
Serve as the software of the most basic bottom work of a system.And in hardware device, firmware is exactly the soul of hardware device, because
For some hardware devices in addition to firmware without other softwares form, therefore firmware also just decide hardware device function and
Performance.As network application is popularized, current server and some industry control class products, can very easily consolidate in upgrading products
Part, so that some important machines can also be upgraded by other operating personnel, causes relevant issues to produce, such as loss of data, new solid
Part is not sufficiently stable.For example, the firmware of the BMC on server, it is easy to updated by network.
In view of this, the utility model provides a kind of system software safety guard, it can avoid software from being grasped by other
Make personnel arbitrarily to upgrade.
【Utility model content】
The technical problem to be solved by the present invention is to provide a kind of firmware upgrade protective device, it can avoid software by it
His operating personnel arbitrarily upgrade.
In order to solve the above technical problems, the utility model provides a kind of firmware upgrade protective device, it includes：
One firmware holder, storage firmware in it；
Switch element, it electrically associates the firmware holder, operates switch element locking or unlocks the firmware holder.
Preferably, the firmware holder be electric erazable programmable read-only memory, erasable read-only memory or
Flash。
Preferably, the firmware upgrade protective device further includes a status displays, it electrically connects with the switch element
Connect, show that the firmware holder is currently in locking or released state.
Preferably, described firmware upgrade protective device status displays is light-emitting diode display.
Preferably, which includes a button, when pressing the button, locks the firmware holder, can not read and write；When
The button is pressed again, unlocks the firmware holder.
Compared with prior art, the firmware upgrade protective device of the utility model can be pinned related by the switch element
The firmware holder of firmware renewal, makes machine protected, it is impossible to arbitrarily to update firmware, the artificial operation of more steps, makes machine
It is safer.
【Brief description of the drawings】
Fig. 1 is a kind of square principle figure of firmware upgrade protective device of the utility model.
【Embodiment】
Refering to Figure 1, the utility model provides a kind of firmware upgrade protective device, it includes a firmware holder 2
An and switch element 3.
The firmware holder 2, storage firmware in it, in the present embodiment, the firmware holder 2 is with EEPROM
(Electrically Erasable Programmable Read-Only Memory), electric erazable programmable read-only memory
Exemplified by, in the other embodiments of the application, the firmware holder 2 or EROM（Erasable read-only memory）Or
Holder read-write Flash etc..
The switch element 3, it electrically associates the firmware holder 2, operates the switch element 3 and locks or unlock firmware storage
Storage 2, in the present embodiment, the switch element 3 include a button 30, when pressing the button 30, lock the firmware holder 2,
It can not read and write；When pressing the button 30 again, the firmware holder 2 is unlocked.
Further, the firmware upgrade protective device of the utility model further includes a status displays 4, itself and the switch list
Member 3 is electrically connected, and shows that the firmware holder 2 is currently in locking or released state.In the present embodiment, the status displays
4 be light-emitting diode display.
By above-mentioned setting, the utility model can be pinned the firmware that associated firmware updates by the switch element 3 and be stored
Device 2, makes machine protected, it is impossible to arbitrarily updates firmware, the artificial operation of more steps, makes machine safer.
The above, is only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art can readily occur in change in the technical scope that the utility model discloses
Or replace, it should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be wanted with right
Subject to the protection domain asked.
