Abstract

PURPOSE:To improve the efficiency of the start and to shorten the total processing time by starting up the system by using a default value address even if an address is not written when the system is started up from a network and then setting an address. CONSTITUTION:An IPL decision means 1 decides whether or not network IPL is performed and when so, a network address is read out of a working memory 2. When the most significant digit bit of the address is 1, it is judged that no address is written and after a temporary network address setting means 5 sets a temporary network, a program loading means 6 loads a program and a correct address is inputted on a keyboard after the program is loaded. Consequently, even when the network address is not written, the system can be started up from the network and the operation is speeded up.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for starting up an information processing device, and particularly to a method for setting a network address for starting up from a network when a network address has not been written.

[Conventional technology]

Conventionally, when starting up from a network, if the network address has not been written, an error occurs, and unless the address is written, it is not possible to start up from the network.

[Problem to be solved by the invention]

In the conventional startup method from the network, the network address is written in the working memory in advance, and the network address is returned to the server device at startup. If it is not written, an error will occur and the system will not be able to start up.The client device will not have the necessary hardware to start up the system, such as a disk device, and will have to start up the system from outside. The drawback is that it cannot be started up with just the client device.

[Means to solve the problem]

The network address setting method of the present invention includes an IPL determining means for determining whether or not it is a network IPL, a working memory for storing a network address, and when the IPL determining means determines that it is a network IPL, the working memory address reading means for reading out a network address from the address reading means; address determining means for determining the presence or absence of the network address read by the address reading means; a temporary network address setting means for setting a temporary network address; and a program loading means for loading a program when a temporary address is set by the temporary network address setting means and when it is determined by the IPL determination means that an address has been written. temporary network address determining means for determining whether a network address is a temporary network address at the time when loading is completed by the program loading means; and provisional network address determining means for inputting an accurate network address and writing the network address to the working memory at the same time. The present invention is characterized by comprising an address input means for entering the address.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, and FIG. 2 is a flowchart showing its operation. This example is an IPL
Consists of determination means 1, working memory 2, address reading means 3, address determination means 4, temporary network address determination means 5, program loading means 6, address setting means 7, and address input means 8 be done.

An IPL determining means 1 for determining whether the network IPL is a network IPL determines whether the network IPL is any other IPL, and if it is a network IPL, the network address is read from the working memory 2. The most significant bit of this address is a flag used to determine whether the correct address has been written. If it is 1, it means that the address has not been written, and if it is 0, it is determined that the address has been written. do. If the address has not been written, the temporary network address setting means 5 sets a temporary network, and then the program loading means 6 loads the program.

If the address has already been written, just load the program. When the program load is finished, determine whether the network address is the temporarily set value or not. If it is the temporarily set address, enter the correct address from the keyboard and save this address to working memory. Write and then exit.

As shown in FIG. 2, it is determined in step 21 whether or not it is an IPL device, and if it is other than a network, step 22 is performed.
Each IPL is executed in step 23, and if it is a network, the network address is read from the working memory in step 23, and the process moves to step 24. In step 24, it is determined whether the flag is 1, and if it is 1, a temporary network address is set in step 25, and the process moves to step 26. If the judgment in step 24 is not 1, step 26
Move to. In step 26, the program is loaded.

In step 27, it is determined whether the loading has been completed, and if the loading has not been completed, the process returns to step 26. If the loading is completed, it is determined in step 28 whether it is a temporary address, and if it is a temporary address, a network address is set (keyboard input) in step 29, and the process ends. The process also ends if the address is not a temporary address.

〔Effect of the invention〕

As explained above, when starting up from a network, the present invention enables efficient startup by starting up the system using a default value address and then setting the address even if the address has not been written. This has the effect of significantly speeding up the overall processing time.
