Access control method and system capable of automatic designing internal storage state in computer platform

Abstract

A access control method enabling to automatically set internal memory state of computer platform includes setting state data exchange line between internal memory control chip and I / O control chip to let I / O state buffer storage image to internal memory state buffer storage through said line for making access program use obtained internal memory specification data to execute internal memory access operation corresponding to said specification based on internal memory state buffer storage. The system for realizing said method is also disclosed.

Description

technical field [0001] The present invention relates to a computer system technology, in particular to an access control method and system capable of automatically setting the memory state of a computer platform, which is applied to a host circuit of a computer platform, such as a host computer of a server using an Intel Corporation Lindenhurst chipset The circuit provides the server with an access control function of automatically setting the memory state. When the user replaces the memory, for example, when changing from DDR-266MHz memory to DDR-333MHz memory, the memory can be automatically set in the server. state, so that the server can access the memory. Background technique [0002] The Lindenhurst chipset developed by Intel is a chipset suitable for dual-processor server architecture, which can support memory modules in multiple frequency states, such as DDR-266MHz and DDR-333MHz DIMM (Dual Inline Memory Module) memory Module (where DDR is Double Data Rate). [000...

Problems solved by technology

[0004] However, in practical application, the disadvantage of the method for setting the memory frequency state of the above-mentioned jumper line is that it is obviously more time-consuming and manpower-consuming to dial the jumper line with manpower, and the specific dialing method of the jumper line also needs to be adjusted. The system administrator consults the relevant operation manual in advance, so the setting process is obviously time-consuming and laborious and inefficient

In addition, if the dialing method of the jumper line is wrong, it may also cause the server to fail to boot.

These shortcomings will make the system management of the server less efficient
