Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

5 is a diagram illustrating a state in which a diagnostic system of a personal computer according to the present invention is loaded into RAM of a personal computer.

As shown in FIG. 5, the diagnostic system of the personal computer according to the present invention is stored in a diagnostic TSR module loaded and executed in an area 500, a diagnostic manager module loaded and executed in an area 510, and an area 530. Is comprised of a plurality of test modules loaded and executed in area 520.

The diagnostic TSR module includes library code means which are commonly performed for the diagnosis of all the devices constituting the personal computer. The diagnostic TSR module may further include initialization code means for checking the specifications of all devices constituting the personal computer and storing them in a predetermined area of the memory. Such a diagnostic TSR module is a Terminate Stay Resident (TSR) module that remains in the basic memory even after the diagnosis is terminated after the initial loading into the basic memory.

In the present invention, the test module for diagnosing each device constituting the personal computer is configured as a separate module for each device or for a predetermined group of devices. Each test module is a program loaded and executed in main memory.

The library code means provided in the diagnostic TSR module are implemented as a BIOS Interrupt Service Routine, and the test modules perform a diagnosis by using a service provided by the library code means by a BIOS interrupt call. Perform.

The diagnostic manager module is an execution module that is loaded into the main memory, stores all the test modules in the continuous memory, and then loads the test modules stored in the continuous memory into the predetermined memory in a predetermined area in order.

At this time, both the diagnostic manager module and the test modules are executable files which return the areas in the main memory and the continuous memory when the execution is completed.

According to Figure 6, the execution of the computer diagnostic software using a continuous memory according to the present invention is as follows.

In the present invention, since data movement between the continuous memory and the main memory is required, a function for supporting the data is required. Such functionality may be provided by the BIOS or may be supported through a separate device drive. According to an embodiment of the present invention, DOS is used as an operating system of a personal computer, and a block move function is used to move data between continuous memory and main memory using a separate device drive called "HIMEM.SYS."

Therefore, in the "CONFIG.SYS" file located in the root directory of the hard disk drive or the floppy disk drive that is the master drive that boots your personal computer, "DEVICE = A: \ HIMEM.SYS" or "DEVICE = C: By setting \ WINDOWS \ HIMEM.SYS ", the" HIMEM.SYS "file must be loaded into the conventional memory of memory while the personal computer is booting (step 600).

In addition, the diagnostic TSR module and the diagnostic manager module are sequentially loaded into the main memory (steps 605 and 610).

The diagnostic manager module loaded in the main memory secures the buffer area 515 to be used for the test and the test module area 520 to be loaded and executed in the main memory (steps 615 and 620).

The diagnostic manager module stores the test module of one of the test modules stored in the hard disk drive or the floppy disk drive in the test module area 520 of the main memory, and then the block move function supported by "HIMEM.SYS". Copying from the test module region 520 to the test module storage region 530 on the continuous memory using steps 625 and 630. These processes continue until all test modules are stored in the test module storage area 530 (step 635).

After all the test modules are stored in the contiguous memory, the diagnostic manager module receives instructions related to diagnosis from the user and transfers the test module from the test module storage area 530 in the contiguous memory using the block move function to the test module area in the main memory ( In operation 520, the process is loaded (step 640, 645). Accordingly, the diagnostic manager module includes a user interface unit including a menu processor, an error processor, and a helper for interfacing with a user. This performance process continues until no further diagnosis is needed (step 650).

When all the diagnostics are finished, the diagnostic manager module frees the used contiguous memory and ends (step 655). When the diagnostic manager module is terminated, the region 510, the buffer region 515, and the test module region 520 in which the diagnostic manager module is loaded are all released, and other programs may be loaded and used afterwards. However, the diagnostic TSR module remains loaded in the main memory even when the diagnostic manager module terminates.

Referring to FIG. 7, the process of installing the diagnostic TSR module in the basic memory is as follows.

The diagnostic system of a personal computer according to the present invention has an optional function for determining whether to install a diagnostic TSR module in a basic memory of the personal computer. Therefore, when the diagnostic TSR module is loaded into the main memory and executed, if there is an Uninstall option when entering a command in DOS, the interrupt vector saved in another area at the time of installation is restored, and the diagnostic TSR module is deleted from the main memory and terminated. (700, 750 steps).

If there is an uninstall option, first to check whether there is a loaded diagnostic TSR module to prevent duplicate loading in the main memory (step 710). If there is already loaded diagnostic TSR module, it outputs a message indicating the fact and ends (steps 710 and 740).

On the other hand, if there is no already loaded diagnostic TSR module, an initialization operation such as checking the specifications of all devices constituting the personal computer and storing them in a predetermined area of the memory is performed (step 720). The existing interrupt vector is stored in a predetermined area, and libraries provided in the diagnostic TSR module are installed in the form of a BIOS interrupt service routine (step 730).

According to FIG. 8, a process in which each test module is performed is as follows.

In the diagnostic system of a personal computer according to the present invention, each test module may be temporarily stored in a continuous memory by the diagnostic manager module and then executed under the management of the diagnostic manager module, and only the diagnostic TSR module is installed, and commands of DOS are provided. It may also be performed separately through the input unit.

First, it is checked whether the diagnostic TSR module is first loaded into the main memory (step 800). If the diagnostic TSR module is not installed, the test module can no longer be executed and a message indicating the fact is output and the process is terminated (step 830).

If the diagnostic TSR module is installed, the controller acquires information provided by the diagnostic TSR module and initializes it to use the library function of the diagnostic TSR module (step 810). Then, the diagnostic process as a single program is performed (step 820).

An embodiment of a diagnostic TSR module, a diagnostic manager module, and a plurality of test modules constituting a diagnostic system of a personal computer according to the present invention may be written as a program executable in a computer system, respectively. And it can be implemented in a general-purpose digital computer system for operating a program from a medium used in the computer system. The medium may be a magnetic storage medium (e.g., ROM, floppy disk, hard disk, etc.), an optical reading medium (e.g., CD-ROM, D.V.D, etc.) and a carrier wave (e.g. Storage medium).

In addition, functional programs, codes, and code segments for implementing the present invention can be easily inferred by programmers in the art to which the present invention belongs.

According to the present invention, even if the size of the diagnostic program increases due to the upgrade of the diagnostic program or the addition of the test module, the limitation of the basic memory area can be overcome by using the continuous memory of the personal computer.

In addition, since the diagnosis is performed by each test module, copying and loading in the continuous memory area without the need of accessing the disk does not cause data loss due to disk access, and the execution speed is also shortened.
