Description

Network card detection method

technical field

The invention relates to a detection method of a network card, in particular to a network card detection method, which can quickly complete the network card without using a floppy disk drive or a hard disk drive, and without additional operating system software such as DOS. The detection methods of various detections of Luca.

Background technique

The traditional detection device and method of the current network card is to prepare a computer plugged with a mother card as a server (referred to as SRV), its hard disk and random access memory (RAM) must have sufficient capacity, and the hard disk A network server program (such as Novell's server program) must be installed. Before testing, first open the server and execute the server program, and select the appropriate frame type when loading the driver program; secondly, Also prepare a computer with a card to be tested as a workstation (WKS for short). This workstation can be booted with a hard disk (or floppy disk). The hard disk (or floppy disk) must contain the NETX.EXE program and the driver of the network card. program, and finally, connect the server and the master card and the card to be tested on the workstation through a transmission line.

When the power of the workstation (WSK) and the server (SRV) is turned on, the workstation is started with DOS, and when the network interface card (NIC) driver in the hard disk (or floppy disk) is executed, the frame type must be set It is the same as the server; then, execute the NETX.EXE program according to the general operation procedure for connecting to the network server, then execute the registration procedure, and enter the user name, and after confirming the connection with the server; The card and the card to be tested carry out various important relevant data (such as: node ID, device ID, vendor ID (or I/O port address) and initialization parameters and other data) and information packet transmission/reception (Tx/Rx) detection action.

In the traditional detection method of this kind of network card, in addition to pre-preparing a computer as a server (SRV) in terms of equipment, another computer must be prepared as a workstation (WKS). The performance must meet the high-performance requirements of the network server (SRV), and the capacity of the random access memory (RAM) and the hard disk must also be large, at least to meet the requirements for the normal operation of any server on the Internet.

In addition, if it is necessary to install multiple testing stations in accordance with the speed of mass production, not only must hard disks or floppy disks be installed on the workstations of each testing station, but also DOS and network card drivers must be stored in the hard disks (or floppy disks) And NETX.EXE and other system software, so the more testing stations, the greater the installation cost of the equipment.

The present invention is aimed at the detection of the network card, as shown in Figures 1 and 2, uses a network card that has been tested and verified as the mother card 2, and the mother card 2 is plugged into a slot 21 of a computer motherboard 1 , and the network card 3 to be detected is plugged in another slot (not shown in the figure), and the same output/input terminals on the two network cards 2, 3 are connected by a transmission line 4 again, that is After the connection is completed, the detection work can be carried out. Before the present invention starts to detect, must be on the bootstrap read-only memory (BOOT ROM) slot position 21,31 of these two network cards 2,3, as shown in Figure 2, be respectively plugged and installed with memory (can be ROM , EPROM, E ² PROM or FLASH ROM) 22,32; And these memories 22,32 can be burnt with network detection program separately or simultaneously, when this personal computer is started, promptly utilizes its bootstrapping characteristic, executes storage The network detection program in these memories 22, 32 is placed on the bootstrap ROM position of the network card to guide the personal computer into the operating environment for detection, and the detection of the network card also starts immediately.

The present invention is directed at the network card when testing, as shown in Figure 3, the central processing unit 11 of the computer 1 first reads the stored detection program from the memory 22 of the mother card 2, and then reads the relevant program according to the program. Important data of the network card, and such important data, such as: node ID, device ID, vendor ID (or I/O port address) and parameters such as initialization, are respectively written into the master card 2 and the card to be tested 3 Among them, the node ID values written in these network cards must be different, so as to meet the characteristic requirements that the node IDs between network cards must not be repeated, and then read the written data from the master card 2 and the card 3 to be tested. The important data of the network card entered, and compared and judged; if the important data of the network card written is wrong through comparison and judgment, then the present invention will display the detection failure on the display screen (not shown in the figure) of the computer information, and remind the testing personnel to turn off the power of the computer for maintenance. Then, repeat the aforementioned testing steps until the master card 2 and the card to be tested 3 pass the test.

If the writing of these important data is completed and the reading is correct, the present invention will respectively initialize the master card 2 and the card to be tested 3 according to the read parameter values, and start to send/receive the data through the network. Receiving detection; the sending/receiving detection is to switch the two network cards to the UTP (Unshielded Twisted Pair) output/input end first, and then send the information packet (packet) by the mother card 2, when the After the card to be tested 3 receives the information packet, the central processing unit 12 of the computer 1 will compare the content of the information packet received by the card to be tested 3, whether it is the same as that sent by the mother card 2, if not, or If the content of the information packet is missing, relevant information will be displayed on the display screen of the computer to remind the testing personnel to check whether the connection is wrong or whether there is a problem with the network card. , to provide the inspector to select the button to continue re-inspection, or to conduct other output/input inspections.

In addition, the card 3 to be tested sends an information packet. After the mother card 2 receives the information packet, the central processing unit 12 of the computer 1 will compare the content of the information packet received by the mother card 2 to see if it is the same as the information packet received by the mother card 2. The ones sent by the card 3 to be tested are the same, if they are not the same, or the content of the information packet is missing, then it will be processed in the aforementioned manner.

If they are the same, the inspector chooses to continue the inspection of other output/input terminals, and switch both network cards to another BNC (Bayonet Nut Connector coaxial cable connector) or AUI (Attachment Unit Interface) output /input terminal, and repeat the above-mentioned action of network transmission/reception detection, and continue to detect until all output/input terminals on the two network cards complete the transmission/reception detection.

The present invention completes all detections, and after judging that the card to be tested 3 has passed the test, the node ID value in the card to be tested 3 is added by one (or a set value) and written back to the mother card 2, so as to detect another When a network card is to be tested, the new node ID value can be burned, so that all network cards that have been tested have different node ID values, so as to meet the characteristic requirement that the node IDs between network cards must not be repeated.

Therefore, the present invention uses a computer mainframe as a detection tool, burns the detection program in these memory devices 22, 32 installed on the bootstrap ROM slot positions of the two network cards, and then utilizes its bootstrap The feature enables the host computer to directly execute the detection program. In this way, not only does not need a floppy disk drive or a hard disk drive, but also does not require additional operating system software such as DOS, and can quickly complete various detections of the network card, saving software or The cost of the hard disk and the long time of booting.
