Embodiment
For structure of the present invention, feature and the function that realized are had clearer understanding and understanding, figure is described in detail in conjunction with the preferred embodiments here:
At first, see also Fig. 1, Fig. 1 is the organigram of one embodiment of the present invention.As shown in the figure, the main structure of present embodiment read-only memory emulator 13 comprises an emulation controller 133, a PCI connector 131 and an internal memory 136.Wherein, emulation controller 133 connects this PCI connector 131 and this internal memory 136 respectively, then stores a Basic Input or Output System (BIOS) (BasicInput/Output System to be measured in the internal memory 136; BIOS).
Be plugged to the PCI slot 111 of a motherboard 11 when read-only memory emulator 13 after, then can be when this motherboard 11 activates, before the internal memory that South Bridge chip decoding CPU (not shown) is sent reads (memoryread) order, utilize emulation controller 133 try to be the first decoding and respond, by obtaining the right to use of pci bus like this.Then, then can carry out stored Basic Input or Output System (BIOS) to be measured in the internal memory 136, by carrying out the test procedure of Basic Input or Output System (BIOS) like this.
Read-only memory emulator 13 also is provided with one and downloads an interface controller 137 and a download interface connector 138.Wherein, this download interface controller 137 is connected in emulation controller 133, can be connected to a computer installation 157 by this download interface connector 138.
Utilize framework of the present invention, the user can write or revise the program code of redaction Basic Input or Output System (BIOS) on this computer installation 157.Write revise finish after, the download interface connector 138 of read-only memory emulator 13 is connected to this computer installation 157, or utilize a transmission line 152 that both are connected, the Basic Input or Output System (BIOS) to be measured that can directly will be stored in computer installation 157 inside is downloaded in the read-only memory emulator 13 via download interface connector 138 and download interface controller 137, and is sent to internal memory 136 inside via emulation controller 133 and is stored.Like this, the user can utilize read-only memory emulator 13 of the present invention to carry out the test of Basic Input or Output System (BIOS) in real time, and need not each one little modification be arranged, and just must carry out numerous and diverse ROM (read-only memory) burning program earlier, just can test then.
Among the present invention, this internal memory 136 should adopt has the internal memory that data write and removed function, for example, and static random-access random access memory (SDRAM) and non-volatile random access memory (Non-Volatile RandomAccess Memory; NVRAM).The transmission interface specification of this internal memory may be selected to be one of them of an ISA (network security and acceleration) and LPC (low pin uses number) interface specification.And the download interface of this download interface controller 137 and download interface connector 138, then may be selected to be one with the transmission interface that reaches convenience fast, for example, USB interface, IEEE 1394 interfaces and wireless transmission interface or the like, be sent to the speed of internal memory 136 and the convenience in the use to improve Basic Input or Output System (BIOS) to be measured by computer installation 157, and reach the whole efficiency that promotes the test Basic Input or Output System (BIOS).
In addition, also can on this read-only memory emulator 13, set up at least one status displays, be connected to emulation controller 133, by the test mode of such demonstration Basic Input or Output System (BIOS) with Presentation Function.In the present embodiment, can select to use as status displayses such as the 80th port (port 80) code translator 134 or the 84th port (port 84) code translator 135, setting by this status displays, state in the test process or the problem that is met with and mistake directly can be presented on the status displays with digital mode, the tester can be to numerical value shown on status displays record in addition, analyzed at each meaning and content that shows the numerical value representative, can make the tester real-time understanding and affirmation can be arranged, and can at any time the problem that is met be solved the test mode of this Basic Input or Output System (BIOS) or the problem that it produced.
In sum, the present invention relates to a kind of read-only memory emulator, relate in particular to a kind of read-only memory emulator of testing Basic Input or Output System (BIOS),, and can test the Basic Input or Output System (BIOS) of different editions by the setting of read-only memory emulator.So the present invention one has novelty, progressive and can utilize on the industry, should meet the key element of China's Patent Law patented claim, so propose application for a patent for invention in accordance with the law.
The above, it only is a preferred embodiment of the present invention, be not to be used for limiting scope of the invention process, all equivalences of being done according to the described shape of the present patent application claim, structure, feature and spirit change and improve, and all should be included in the claim of the present invention.
