Abstract
The present invention relates to a device for monitoring start processes of personal computer systems. Parallel ports are used in stead of industry standard architecture (ISA) cards; meanwhile, a host board does not need to be provided with an ISA slot or an ISA bus, and a display device for connecting parallel port connectors is used for displaying energized self-test codes so as to achieve the goals of system start process monitoring and low cost.
Description
Technical field
The present invention relates to a kind of device of monitoring start process of personal computer system, particularly relate to a kind of need not on motherboard, to dispose ISA groove and use ISA card, but reach the device of surveillance start process with parallel port replacement ISA card.
Background technology
In the society of scientific and technical information prosperity now, because computer can be widely used in multimedia, network, storage data, signal transmission ... on many-side, make computer almost become one of indispensable basic tool of all trades and professions institute, even reach the stage that every household all has a computer at least soon.
Usually, why a PC (Personal Computer-PC) can operate running smoothly, we can say that driving other accessories by this core material of central processing unit entirely operates execution, and then reaches situation about operate smoothly.Yet, but peripheral accessory is indispensable, if there be not cooperatively interacting of these peripheral accessories, computer is bound to can't normal operation and operation.
In PC, Basic Input or Output System (BIOS) (BIOS) every one section code (code), can be passed through specific input/output end port in the process of boot program (boot), send special energising self-test (Power On Self Test; Hereinafter to be referred as POST) code.Traditionally, generally all be with industrial standard architectures ((Industry Standard Architecture; Hereinafter to be referred as ISA) card, being commonly called as port 80 cards (Port80 Card) is inserted on the ISA groove (slot) of motherboard (Mother Board), wherein the ISA card is mainly used to monitor PC system boot situation, and behind the POST code that pinning BIOS sends, (LED) demonstrates with light emitting diode.But on the PC in future host board structure, ISA groove or isa bus will be removed, and then this kind ISA card just can't use.In addition, use, will cause the increase of cost if the ISA card is made periphery connection interface (PeripheralConnection Interface-PCI) card.
Summary of the invention
The object of the present invention is to provide a kind of device of monitoring start process of personal computer system, to solve on following PC host board structure, the ISA groove will be removed the problem that causes the ISA card to use.
In order to reach above-mentioned and other purposes of the present invention, a kind of device of monitoring start process of personal computer system, use parallel port to replace ISA port 80 cards, need not the ISA groove on the motherboard simultaneously, and demonstrate energising self-test code, but to reach surveillance start process and purpose cheaply by the display device that connects the parallel port connector.
The object of the present invention is achieved like this, and a kind of device of monitoring start process of personal computer system promptly is provided, and comprising: a motherboard; One parallel port controller is disposed on this motherboard, and this parallel port controller has a FPDP, and the I/O address setting of this FPDP is a system debug port; And a parallel port connector, being disposed on this motherboard, and connecting this parallel port controller, this parallel port connector is in order to receive an energising self-test code of this parallel port controller.
The present invention also provides a kind of device of monitoring start process of personal computer system, comprising: a motherboard; One parallel port controller is disposed on this motherboard; A plurality of FPDP are disposed on this parallel port controller, and an I/O address setting of this each FPDP is a system debug port; And a parallel port connector, being disposed on this motherboard, and connecting this parallel port controller, this parallel port connector is in order to receive an energising self-test code of this parallel port controller.
The present invention also provides a kind of device of monitoring start process of personal computer system, comprising: a motherboard; One parallel port controller is disposed on this motherboard, and this parallel port controller has a FPDP, and the I/O address setting of this FPDP is a system debug port; One parallel port connector is disposed on this motherboard, and connects this parallel port controller, and this parallel port connector is in order to receive an energising self-test code of this parallel port controller; And a display device, connect this parallel port connector, in order to show this energising self-test code.
Description of drawings
Below in conjunction with accompanying drawing, describe embodiments of the invention in detail, wherein:
Fig. 1 is the device synoptic diagram according to a kind of monitoring start process of personal computer system of a preferred embodiment of the present invention.
Embodiment
On the PC host board structure that will solve in future, the ISA groove will be removed the problem that causes the ISA card to use, and please refer to Fig. 1, and it illustrates is device synoptic diagram according to a kind of monitoring start process of personal computer system of a preferred embodiment of the present invention.
The present invention adds some designs with parallel port controller (Parallel PortController) 12 in 1284 standards of the IEEE on the motherboard 10, replaces the function of ISA card.
According to preferred embodiment of the present invention, one is changed into system's debug (debug) port (its address is generally 80h) with I/O (I/O) address of parallel port controller 12 FPDP; It two increases a data port in parallel port controller 12, its I/O address is at system's debug port (80h), and so parallel port controller 12 just can pin the POST code, and it is delivered to parallel port connector 14 on the motherboard 10.
In addition, we can connect a display device that can show the POST code on parallel port connector 14, for example be a seven-segment display 16, so the POST code of system boot program can show by seven-segment display 16, to make things convenient for the situation of our surveillance boot program.
Therefore, by device of the present invention, ISA port 80 cards just can be replaced by parallel port cheaply, need not the ISA groove simultaneously.
In sum, characteristics of the present invention and advantage are to use parallel port to replace the ISA card, need not to dispose the ISA groove on the motherboard simultaneously, and demonstrate energising self-test code, but to reach surveillance start process and purpose cheaply by the display device that connects the parallel port connector.
Though disclosed the present invention in conjunction with preferred embodiment; yet it is not in order to limit the present invention; those skilled in the art without departing from the spirit and scope of the present invention; should be used for a variety of modifications and variations, so protection scope of the present invention should be considered as appended being as the criterion that claim defined.
