Embodiment Construction

[0012] In order to solve the problem that the ISA slot will be removed and the ISA card cannot be used in the future structure of the PC motherboard, please refer to figure 1 , which shows a schematic diagram of a device for monitoring the boot process of a personal computer system according to a preferred embodiment of the present invention.

[0013] The present invention replaces the function of the ISA card with the IEEE 1284 standard parallel port controller (Parallel PortController) 12 on the motherboard 10 plus some designs.

[0014] According to a preferred embodiment of the present invention, one changes the input / output (I / O) address of the parallel port controller 12 data ports at the system debugging (debug) port (its address is usually 80h); A data port is added in the port controller 12, and its I / O address is at the system debug port (80h), so that the parallel port controller 12 can lock the POST code and send it to the parallel port connection on the motherboar...

Abstract

A device for monitoring the start process of personal computer system features the use of parallel port instead of ISA card, no need of ISA slot and ISA bus on host machine board and the use of parallel port adapter to connect display for displaying self-test codes. Its cost is lower.

Description

technical field [0001] The invention relates to a device for monitoring the booting process of a personal computer system, in particular to a device which does not need to configure an ISA slot and use an ISA card on the motherboard, but replaces the ISA card with a parallel port to monitor the booting process of the system. Background technique [0002] In today's society with advanced technology and information, because computers can be widely used in multimedia, network, storage data, signal transmission, etc., computers have almost become one of the indispensable basic tools in all walks of life, even It has almost reached the point where every household has at least one computer. [0003] Usually, the reason why a personal computer (Personal Computer-PC) can operate smoothly can be said to depend on the core of the central processing unit to drive other auxiliary parts to operate and execute, and then achieve the situation of smooth operation. However, the peripheral a...
