TW501006B - Information processing system with power-on debugging function and the power-on debugging method - Google Patents

Abstract

The present invention provides an information processing system with power-on debugging function comprising a built-in display mechanism. Before the power-on self test of the basic input/output system (BIOS), the display mechanism is initialized first; next, before executing each testing operation in the power-on self test process, the code for each test point is shown on the display mechanism; thus, when error occurred in the power-on self test process, the test operation will be immediately stopped to halt the system, and the code for the test point occurring the error can be read on the built-in display mechanism.

Description

J " 106. V. INTRODUCTION TO THE INVENTION (1) Field of the Invention The present invention relates to an information processing system, and more particularly to a built-in display panel 'power-on se 1 f-test, post ) When the test point code is displayed for the information processing system of the debugging function. '' Background of the Invention When an information processing system such as a computer is reset or started, the basic input / output system (Bios) performs a power-on-self-test p〇ST on the hardware ),: Also :: The two processors' calculations, graphics cards, memory, disk drives, etc., perform trial operations. Every test during this hardware test = f Dong Beicai said one code. The conventional BIOs program reports f, g A e, ..., the code will be output to a specific I / 0 port (usually port 80h).饤 疋 i / υ 垾 Wrong in the development of information processing systems. Objectives: It is known that computers and BIOS manufacturers ==, IOS remove the shells, and use a method that uses J, which is achieved by using a computer: a board. When P0ST executes ;;;; ::: The interface card is plugged into the host. When the error occurs, the test action will stop immediately. One copy of the hardware function occurs = two digit seven-segment display to watch the test d, you can d copy through the interface card. However, this method uses ‘Go code’, and it ’s very inconvenient to learn that some of the motherboard board ’s space has an error, and it ’s necessary to reserve a j-type trend. Not only is it a waste of space, it is also inconsistent. A daughter card with a display circuit is externally connected to another conventional method. It is 501006 V. Invention Description (2) ^, the port receives test point codes output to port 80h. However, it seems that "electronics will gradually develop towards the concept of Legacy Free. At that time, the computer will no longer have a printer port, but only a USB port, so it will not be possible to debug in the manner of connecting to a daughter card other than the above. OBJECTS AND SUMMARY OF THE INVENTION The purpose of this invention is to provide an information processing system with a boot debugging function and a boot debugging method, which uses a built-in display panel of an information processing system * to display a boot self-test ( p〇ST,

Self-Test) test point code, so you don't need to connect any daughter card or interface card to achieve the debugging function. The information processing system with startup debugging function of the present invention includes a built-in display mechanism. When the basic input / output system (BIOS) starts to perform the power-on self-test, the display mechanism is first initialized. Next, each test point code is displayed on the display mechanism before the test is performed during the startup self-test. Hunting for this, when an error occurs during the self-test during startup, the test action will be immediately stopped and the system will be set. When necessary, the test point code where the error occurred can be read from the built-in display mechanism.

Therefore, according to the present invention, it is not necessary to reserve a part of the motherboard for an external debugging interface card, which saves space and cost and improves the utilization rate. m is an information processing system which does not have a printer port and cannot be connected to an external interface card, and can further show the effect of the present invention. The other advantage of the present invention is that a general computer has a system test error, which can be easily built-in.

Write down the code, report to the service center and ask how to troubleshoot. In this way, for some simpler problems, the service center can immediately teach the user the method. Therefore, users do not need to return the system to the service center for inspection every time an error occurs, which not only improves efficiency but also saves unnecessary costs. ^ At present, some notebooks or LCD display shows that the built-in LCD display needs to be installed separately. The computer has a built-in LCD ‘showing and playing track of a music disc. The panel can be used as the display device of the present invention, so the panel is not shown at all, so it can be turned on. In this case, the display is not structured, and no additional schematic block diagrams are added. Figure 1 of the program is the information processing system of the present invention. Figure 2 is the first detailed example of Figure 1. , Knife flow chart of the basket example; and boot self-test (figure 3 is the flow chart of the preferred specific example of FIG. 1).
