Problems solved by technology

As for the other hard disk drive 24, the status update signal sent by it cannot be sent to the back-end computer system through the transmission engine 121 to obtain a corresponding response.
In this way, it is possible that the hard disk drive 24 cannot enter the normal operation state due to waiting for a long response time, and it is also easy to cause the computer system itself to crash due to the abnormal operation of the hard disk drive 24.

Embodiment Construction

[0032] Please refer to Fig. 3 first, which is a functional block diagram of the personal computer system on which the method of the present invention is applied, which is a partial functional block diagram of a personal computer system, which mainly includes a central processing unit 30, a core Logic chipset 31, SATA host controller interface 34 and SATA bus 32, and SATA bus 32 respectively includes physical layer devices (physical layer devices) 327, 328, 329, 320, data link layer devices (data link layer device) 323 , 324, 325, 326 and a first transport engine (transport engine) 321 and a second transport engine 322. But because on the SATA bus 32, the first transmission engine 321 is utilized to serve the first hard disk drive 331 and the second hard disk drive 332 simultaneously (such as a common master-slave mode), and the second transmission engine 322 is utilized to serve the third hard disk drive 333 in addition simultaneously , the fourth hard disk drive 334 . Theref...

Abstract

The method is applicable to PC including bus transmission engine, which is shared by first bus module and second bus module. The method includes following steps: first, in time of starting up PC, disabling link operation from the first bus module and the second bus module to the bus transmission engine; when enabling link operation between the bus transmission engine and the first bus module and completing the link, the method makes the first bus module is enabled to send out a first state update signal; when receiving the said first state update signal, the PC enables the bus transmission engine to be changed to link to the second bus module; after completing the link, the second bus module is enabled to send out a second state update signal to the PC.

Description

technical field [0001] The invention relates to a bus component initialization method, in particular to a bus component initialization method applied in a computer system. Background technique [0002] Please refer to FIG. 1, which is a schematic diagram of some functional blocks inside the personal computer system, which mainly includes a central processing unit 10, a core logic chipset 11, and a serial advanced technology attachment (Serial Advanced Technology Attachment, hereinafter referred to as SATA) bus 12 And hard disk drive 13. Since the new generation of SATA bus 12 adopts serial mode for data transmission, compared with the traditional advanced technology additional interface (abbreviated as ATA) bus for parallel mode transmission, it has faster speed, thinner and longer cables, and better heat dissipation. It is the transmission interface adopted by the new generation of high-speed hard drives. [0003] When a hard disk drive 13 is connected to the SATA bus 12 ...
