Abstract

PURPOSE:To attain the start of a set-up program without using a test program by starting the set-up program at the time of confirming whether the interruption caused by the external switch during the processing of NMI interruption is depressed at the time of power ON or reputing time. CONSTITUTION:The subject system is provided with a hardware switch 2 to be driven by set-up processing, a means for forming non-maskable interruption when the switch 2 is turned on, an interruption processing program for deciding whether an interruption is based upon the switch 2 or another factor, and the 2nd means in the interruption processing program for deciding whether the switch 2 caused by the generation of the interruption is depressed at the time of power ON or reputing time. At the time of power ON or reputing time, the set-up program is started to allow a user to urge the input of the system constitution information. Consequently the set-up program can be started without being influenced by an operating system and the system constitution can easily be changed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a setup startup method suitable for use in a personal computer.

(Prior Art) Personal computers allow users to freely set setup information in order to notify applications of the system configuration. In order to set this setup information, a setup program owned by the system must be started. A common method for starting the system is to use a test program attached to the system.

(Problems to be Solved by the Invention) A test program runs in an OS (operating system) that is standardly used in the field of personal computers. Therefore, it is possible to start setup using a program under this woos, but if you are using a relatively high-performance O8 and are upgrading the system under this O8, you may not be able to use the test program. . Therefore, -dan, standard O
There was an inconvenience that the test program had to be used and started after starting up from 8.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a setup startup method that allows setting of stem configuration information regardless of the type of O8 in the above usage environment.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides hardware for starting setup processing in a computer system in which a user arbitrarily sets setup information at the time of system initialization and transmits it to an application program. A switch, a means for generating a non-masked interrupt when the switch is turned on, a processing program for the interrupt that determines whether the interrupt is caused by the switch or another factor, and if it is a switch, whether it was pressed at power-on or rebooting. and a second means in the interrupt processing blockrum for determining whether or not the interrupt processing block is enabled, and is characterized in that when power is turned on or rebooted, the setup program is activated to prompt the user to input system configuration information. .

(Function) The present undergarment invention has the above-mentioned configuration, and the external switch allows the 8M1
Generates an interrupt, checks the interrupt cause during 8M1 interrupt processing, and determines whether the 8M1 interrupt is caused by an external switch and was pressed at power-on or reboot, or at any other time. If this is confirmed, start the setup program. This makes it possible to perform setup startup without using a test program.

According to the present invention, setup can be started without being influenced by O8, and the system configuration can be easily changed.

(Example) Hereinafter, an example of the present invention will be described in detail using the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, reference numeral 1 denotes a CPU, which reads and executes an initial diagnosis block diagram and a setup program stored in a ROM 3. Reference numeral 2 is an external switch, which includes a circuit that generates an 8M1 interrupt. Code 3 is R
OM, and stores the above-mentioned initial diagnosis program, setup program, etc. Reference numeral 4 denotes a main storage device, which serves as a work memory used when executing each program. Reference numeral 5 denotes a CRT monitor, which displays system configuration items using a setup program.

FIG. 2 is a flowchart showing the operation of the embodiment of the present invention. In the figure, reference numeral 101 is a step for determining the cause of the interrupt, and it is determined whether the interrupt is caused by a switch or another interrupt. Reference numeral 102 is a step for determining when the switch was pressed, and it is determined whether the switch was pressed at power-on, rebooting, or at any other timing.

Reference numeral 103 is a step knob that starts the setup program, and when the switch is pressed at power-on or reboot, the setup program is executed.

Hereinafter, the operation of the embodiment of the present invention will be explained in detail. If the external switch 2 is not pressed at power-on or reboot, an initial diagnostic program is executed as normal processing, and if there is no abnormality in the system, O8 is executed. If the externally provided switch 2 is pressed, an 8M1 interrupt occurs, and the process shown in FIG. 2 is performed after the initial diagnosis program is executed.

To explain in detail using Fig. 2, first, when switch 2 is pressed, an 8M1 interrupt occurs, and during the interrupt processing, a process is performed to determine whether the cause of the interrupt is caused by the switch or something else. is performed in step 101. In the case of an interrupt caused by the switch 2, a determination process is performed in step 102 as to whether the switch was pressed during initial diagnosis at power-on or reboot, or was pressed for some other reason.

If it was pressed during initial diagnosis at power-on or reboot, the setup program is called in step 103, and once the user has completed the settings, the initial diagnosis program is executed again according to the set values and the system is installed. If there is no abnormality, control returns to O8.

[Effects of the Invention] As described above, according to the present invention, setup can be started without being influenced by O8, and the system configuration can be easily changed.
