In addition, it is possible to improve the reliability of the write data and prevent a mistake in the write operation, thereby improving the operation efficiency.

[0002]

2. Description of the Related Art A MACROM writing system is a ROM (Read Only Memory) mounted on a network card.
MAC address (Media Access
This is a system for writing data such as firmware including Control Address).

The term “MACROM” is a unique M
Refers to a ROM in which data such as firmware including an AC address is stored.

FIG. 9 is a block diagram showing a configuration of a conventional MACROM writing system. In the figure, 91 is a computer, 92 is a printer, 93 is a MAC attached to a ROM.
Label with address printed, 94 is ROM writer, 9
5 is a master RO storing data to be written to the ROM.

Data to the ROM and the ROM via the printer 92.
MAC to control printing of labels to be attached to
This is a ROM writing unit.

FIG. 9A shows a MACROM writing system in which data to be written to a ROM is read from a master data storage section 96 in a computer 91 and set in a ROM writer via a serial interface, and has a relatively small master data capacity. Used in case.

FIG. 9B shows a MACROM writing system for reading data to be written in the ROM from a unique master ROM 95 and setting the data in a ROM writer, and is used when the capacity of the master data is large.

[0009] In FIG. 9, reference numeral 98 denotes a work content, for example, work date, after using the MACROM writing system.
This is a work history ledger in which the written MAC address range, ROM drawing number, worker name, work instruction date, and the like are written by the worker.

Referring to FIGS. 6 to 8, a conventional MAC
The processing of the ROM writing system will be described.

FIG. 6 is a processing flowchart of one embodiment of a conventional MACROM writing unit, FIG. 7 is a diagram showing an example of the configuration of a MAC address, and FIG. 8 is a display screen of one embodiment displayed by a conventional MACROM writing unit on a display unit. It is.

As shown in FIG. 7, a MAC address generally includes a vendor code (3 bytes) indicating a manufacturer, a model code (1 byte) indicating a model identification, and a serial number (2 bytes) indicating a manufacturing number. Have been.

A display screen 81 shown in FIG. 8 is a display screen of a work for creating a MACROM, and has a worker name, a work date,
Input fields of work data such as a ROM drawing number and its version number, a MAC address for designating a MAC address to start creation as a write condition, and a quantity for designating the number to be created are displayed, and the progress of the work is shown at the bottom. A counter and a message indicating the work status are displayed.

According to the flow of FIG.
The operation of the writing unit will be described.

Step S601: The operator name and R are displayed on the display unit.
A display screen 81 for acquiring work data such as the OM drawing number, version number, and writing conditions is displayed, and each data is acquired.

Step S602: Labels are printed by the number of designated ROMs.

Step S603: Data stored in the master data storage unit or the master ROM is set in the ROM writer.

Step S604: MAC address data is created and set in the ROM writer.

Step S605: The data set in the ROM writer is written in the ROM by the processing in steps S603 and S604.

Step S606: A verify check of the data written in the ROM is performed.

Step S607: Next MAC address,
That is, it is checked whether the next serial number can be assigned.

Step S608: MACROM created
Is instructed to paste the label corresponding to.

Step S609: The MACROM creation counter is updated, and the counter is displayed on the display unit.

Step S610: It is determined whether or not the writing of the number specified in step S601 has been completed. If the creation has been completed, the process ends. If the creation has not been completed, the process returns to step S604.

[0023]

However, the prior art shown in FIG. 9 has the following problems. (1) There are a plurality of MACROM writing systems corresponding to the amount of data to be written to the ROM. Further, since the operation method differs for each system, workability is poor. (2) All labels indicating the MAC address are printed before the ROM writing operation is performed, and when the writing of each ROM is completed, the label written by the operator is written in the ROM.
Pasted on. Therefore, a label having a different MAC address may be attached to the ROM. Also, when the writing of the ROM is interrupted due to a hardware abnormality or the like, a label that has not been pasted remains. Then, when the system is started, labels are printed, and the same labels are present in the process, resulting in poor work efficiency.

(3) At the time of writing to the ROM, the user may forget to replace the ROM of the ROM writer and rewrite the already written ROM, resulting in poor work efficiency. (4) Since only a verify check is performed on the ROM after writing in the ROM, a write failure MACRO
M may not be detected.

(5) When the serial number forming the MAC address can no longer be assigned, an error message is displayed on the display unit. For this reason, the work is stagnated until the numbering work performed in another department is completed. (6) Since the progress of the writing operation of the ROM is displayed by the counter, it is difficult to confirm the progress.

(7) The work efficiency is poor because the worker writes work history such as the ROM writing work date, the MACROM address of the writing work, and the worker name in the ledger.

[0027]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-described problems. In a MACROM writing system, before writing data to a ROM, an RROM is used.
A means for confirming that no data has been written to the OM. Also, after writing data to the ROM, read data from the ROM, verify check, MAC address data check, MAC address sum check, all data sum check, etc. Means for performing data write to the ROM, and means for confirming that the same MAC address as the written MAC address has not been previously written, thereby preventing data overwrite, confirming data reliability, and so on. It is possible to prevent provision of a defective MACROM.

[0028]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In a MACROM writing system, there is provided a means for selecting data of a master ROM to be loaded into a ROM writer from a master data storage section for storing data of a plurality of master ROMs and a unique master ROM. Therefore, it is not necessary to learn how to operate a plurality of MACROM writing systems, thereby improving work efficiency.

Before writing data to the ROM, R
By providing a means for confirming that data has not been written to the OM, data overwriting can be prevented, and the occurrence of work errors can be eliminated.

After writing data to the ROM, the RO
The reliability of the data written in the ROM can be improved by providing means for reading the M data, verifying the check, checking the MAC address data, checking the MAC address sum, checking the sum of all data, and the like. Thus, provision of a defective MACROM can be prevented.

Further, by providing a means for confirming that the same MAC address as the written MAC address has not been previously written after writing data to the ROM, the provision of the MACROM in which the same MAC address has been written is prevented. It becomes possible.

After writing data to the ROM, MA
A means for comparing the serial number of the C address with a predetermined value and displaying a warning message on the display unit when the serial number is equal to or less than the predetermined value allows the serial number of the MAC address to be assigned in advance. It is possible to improve work efficiency.

When the MACROM writing operation for one ROM is completed, the operation history such as the ROM writing operation date, the MACROM address of the writing operation, and the operator name is stored in the storage unit. By providing the means for displaying the work history on the display unit, the work of recording the work history can be eliminated.

Further, by providing a means for printing a label of the MAC address corresponding to the write data every time the writing of the ROM is completed, it is possible to prevent the label of the MAC address from being stuck and the printing of the label of the unnecessary MAC address. It can be eliminated.

Further, by providing means for displaying the progress of the writing operation of the MACROM in a graph,
The progress of the M writing operation can be grasped at a glance and easily.
