Problems solved by technology

[0007] When the PCI-E interface controller on the mainboard of the computer is configured with a slot, the system will allocate system resources to the bridge of the PCI-E interface regardless of whether an expansion slot card is plugged into the PCI-E interface. (such as IO, MMIO, IRQ), those bridges that do not have a bus interface that is plugged into an expansion slot card will waste system resources, and if the BIOS is forced not to allocate system resources to those bridges that do not have an expansion slot card on the PCI-E interface resources, some OS operating systems (such as MS windows 2000, MPS mode of 2003) will have error signals on the device

Embodiment

[0019] see figure 1 , which is a flow chart of the method for saving system resources in the present invention. As shown in the figure, the method for saving system resources of the present invention is applied in a computer system with a BIOS program, and the method includes the following steps: first, step S10 is carried out, and the basic input and output system (BIOS) executes a boot self-test program, Then proceed to step S20.

[0020] In step S20, it is determined whether the data of a first storage unit is invalid, if yes, proceed to step S30, if not, proceed to step S40.

[0021] In step S30, according to the identification code on an expansion card (Riser Card), the currently inserted expansion card is known, thereby knowing the bridges corresponding to all expansion slots on the expansion card, and all corresponding bridges The position value of the device is recorded in the internal value of the first storage unit, and then step S40 is performed.

[0022] In step...

Abstract

A method for saving system resource includes activating bridge corresponding to bus inserted with expansion slot card and writing information of bridge activated bus in the first storage when start-up self-test program is executed by BIOS, only distributing system resource to bridge on activated bus by BIOS when PnP algorithm program is executed by BIOS, using chip set to carry out configuration on width of bus with expansion slot card for making bus interface support maximum bus width to raise data transmission speed.

Description

technical field [0001] The invention relates to a method for saving system resources, in particular to a method for effectively allocating bus interface bandwidth and saving system resources. Background technique [0002] With the advancement of electronic and computer technology, the functions realized are more and more powerful, and new functions can be added by carrying new peripheral devices, but after carrying new peripheral devices, the computer system must be restarted to install the drivers of the peripheral devices, so , it is necessary to stop the existing operations, which is very cumbersome and inconvenient in actual use, especially for servers and other equipment that have high requirements for time continuity and high reliability, which will cause serious consequences such as data loss and service interruption. [0003] For this reason, the industry promptly proposes a kind of expansion slot card (Slot Card) interconnection technology with hot-swappable functio...
