Abstract

PURPOSE:To make it possible to select a registered file at the time of initialization and to provided the information processor with flexibility by selecting a registered file from a master registered file, loading the selected file from an external storage device to an internal storage device and executing initialization based upon the registered file. CONSTITUTION:At the time of staring the information processor, whether a disk operating system (DOS) 132, plural initialized (registered) files 135 and a file (master registered file) 134 having file names as its contents exist or not is checked, and when these contents exist, the contents are read out and a group of the file names of the registered files is displayed on a screen as a menu. If no key input is obtained, the file registered in the head of the file 134 is selected and processed to end the initialization. Thereby, power saving can be attained in many cases by registering the file to be most frequently used in the head of the file 134.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an initial stage of DO3 in an information processing device [Prior Art] A typical startup method of DO3 used in a conventional information processing device such as a personal computer will be explained with reference to FIG.

Immediately after power-on or reset, the basic input/output and system (hereinafter referred to as R
OM-BI○S) loads the boot program in the disk (3200). The boot program also loads DO3, 210) transfers control to DO3, D
O3 is the hardware initialization (initialization (A)) (322
0)), loading a collection of various peripheral device drive programs (hereinafter referred to as device drivers) and securing the DO3 work area (initial settings (B) (3230)), execution of an automatic startup user program (initial settings (C)) (3240))
After performing various initial settings, the system enters a command waiting state (3250).

Initial settings (B) (3230) are the name of the device driver created in advance that you want to load and the DO3 to be secured.
This is done based on a registration file in which parameters giving the size of the RAM area are registered.

Although it is possible to load and unload some device drivers after starting DO3, the settings of some device drivers are determined by the contents of the registration file. Furthermore, the disk buffer and DO3 work RAM area for file reading are determined by the registered file, and cannot be changed later.

Further, the parameters for the DO3 working RAM area have values that provide the highest efficiency depending on the usage type, and it has become necessary to switch the values of these parameters.

If a registration file is prepared once, a problem arises in that the registration file must be rewritten each time the above settings are changed.

It is an object of the present invention to provide a highly flexible initial setting mechanism that allows a registration file to be selected at the time of initial setting of DO3.

[Problems to be Solved by the Invention] However, in the conventional technology described above, in order to use many peripheral devices, it is necessary to load many device drivers in advance, which requires more RAM. Therefore, it has become necessary to switch the loading mode of the device driver depending on the mode of use, such as when it is necessary to use a large amount of RAM and when it is not necessary.

[Means for Solving the Problems] An information processing device according to the present invention includes a disk operating system (hereinafter referred to as DO3), a plurality of initial setting files (hereinafter referred to as registration files), and 1 whose contents are the names of the files. an external storage device containing one file (hereinafter referred to as a large registration file); an internal storage device that stores the contents of the external storage device; The present invention is characterized in that it includes a mechanism for loading into an internal storage device and performing initial settings based on the registered file.

[Example code] Embodiments of the information processing apparatus according to the present invention will be described below.

The information processing device according to the present invention has a CPU (1
00) and the path line (110) connected to it, ROM
(120), BOS in ROM (121), external storage device (130), boot program (131), DO3
(132), initial setting format selection routine (133), large registration file (134), multiple registration files (135)
), various input/output devices (display section (150), keyboard (160), printer (170), R3232C (18
0)). In addition to these, other input/output devices (1
90) can also be added.

An explanation of the DO3 activation style by this information processing device is shown in FIGS. 2 and 3. FIG. 3 shows the initial setting (
B) Selection of format (3229).

This shows the initial settings (B) (3230).

At startup, DO3 checks whether the large registration file exists (3310), and if the large registration file does not exist,
Setting based on predetermined standard values (3321)
Perform the initial setting (B) (323
0) shall end.

If the large registration file exists, load it (
3320), and displays a menu of names of registered files registered thereon on the screen (3330).

Time measurement is started (3340), and input from an input device (here, a keyboard) is checked (3350).

If there is no input from the keyboard, check the time (33
60) Check if a time limit (on the order of a few seconds, e.g. 5 seconds) has been exceeded (3370), and during the time limit (S350) unless there is key human power (5360) (3370)
repeat. If you do not have the key manpower even after the time limit has passed, select the registration file registered at the beginning of the large registration file (3380) and process it (5390).
, the initial setting (B) (3230) shown in FIG. 2 is completed. Therefore, by registering the most frequently used registration file at the beginning of the large registration file, labor can be saved in many cases.

Now, if there is any input from the keyboard, its value is checked (3361) and an action is performed depending on the type of key. If the cursor movement key is used, the registered file candidates are switched (S372), and if the return key is used, the selection of the registered file candidate at that time is confirmed (S33).
71). After that, the process described in the registration file is performed (3390), and the initial settings (B
) (3230) shall end.

[Effects of the Invention] According to the above-described invention, when using a disk operating system (hereinafter referred to as DO3) in an information processing device such as a personal computer, it is possible to load peripheral device drive programs, secure a DO3 work area in RAM, etc. The user can select the initial setting format when starting the DO3, which has the effect that the registration file does not need to be rewritten every time the above settings are changed.
