Description
[technical field]
The present invention is the system and method that closes at a kind of graphical interfaces when being used for the supervisory control comuter start, particularly close a kind of by network the system and method for the graphical interfaces during in the start of monitoring client monitoring remote computer.
[prior art]
The computer nowadays graph technology is used quite extensive, and VGA (Video GraphicsArray, striograph figurate number group) technology is a gordian technique of computer graphics techniques.Computer nowadays generally all the Graphics Application display card activate Computer Graphic Demonstration, the relevant information of some and graphic presentation all is stored among the Video RAM (Random Access Memory), this Video RAM is meant a kind of erasable internal memory that is solidificated on graphic presentation (VGA) card, and its image data storing mode is different different because of the display chip on the graphic display card.Image store district (Video Memory) is that previous IBM is for storing a kind of standard of MONO, EGA, CGA, VGA image information institute agreement, its address fix and form certain, though can not being used for now, the Windows system of high image quality shows, but all computing machines all use this mode, all graphic display cards all to support when activating figure and need not provide driver.
IBM protocol of I BM VGA when start graphics mode is to come initialization graphic display card parameter by starting BIOS (Basic Input-Output System, Basic Input or Output System (BIOS)) program during by computer booting, to reach the purpose that activates graphic presentation.Every hardware to computer system when BIOS is responsible for starting shooting carries out initialization setting and test, can operate as normal to guarantee system.If hardware is undesired then to quit work immediately, and a facility information of makeing mistakes feeds back to the user.BIOS is stored in CMOS (the Complementary Metal-Oxide Semiconductor on the computer main frame panel, complementary metal oxide semiconductor (CMOS)) in the internal memory, be the batch processing that is used to get in touch between computer hardware and the software, this program provides lowermost level and the most direct hardware controls for computing machine.After the computing machine energized, BIOS will check the computer-internal all devices, comprise CPU, internal memory, graphic display card, audio cards, system host board, CMOS internal memory, parallel and serial communication subsystem, floppy disk and the hard disk subsystem and keyboard are tested.After self-checking is finished, operating system will be sought by system in the driver of appointment, and in internal memory loading of operating system, and then make the computer system operate as normal.
The user is that the graphical information of obtaining in the remote computer start process adopted a lot of technology, and traditional technology is general to adopt the bios program by remote computer that the graphical information in the start process is outputed to a monitor card from serial port; Or directly go to capture the graphical information among the Video RAM on the graphic display card by monitor card, by monitor card the graphical information of acquisition is shown to the user by Network Transmission to the software of monitoring computers again.Yet the above-mentioned efficient of obtaining the graphical information in the remote computer start process must be subject to the speed of general serial port, also can use different chips because of each tame graphic display card manufacturer sometimes, and cause monitor card can only support specific graphic display card.
For overcoming the deficiency of above-mentioned prior art, graphical interfaces supervisory system and method when the invention provides the start of a kind of remote computer, by the image store district of standard on a kind of PCI monitoring management card direct access remote computer, it is not limited by graphic display card or VGA chip.
