Embodiment Construction

[0024] refer to figure 1 , a kind of notebook onboard memory compatible multi-source method that the present invention proposes, comprises the following steps:

[0025] S1. Set up the memory mark generation circuit. The memory mark generation circuit includes a power supply terminal, a ground terminal and a plurality of mark generation nodes. Each mark generation node can disconnect the conductive connection power supply terminal, and can disconnect the conductive Connect the ground terminal.

[0026] In this embodiment, the memory mark generation circuit includes four mark generation nodes, and each mark generation node corresponds to a pull-up resistor and a pull-down resistor. The pull-up resistor has two states: on and off. , indicating that the generation node is connected to the power supply terminal through the pull-up resistor. In the unloaded state, it indicates that the generation node is disconnected from the power supply terminal; the pull-down resistor has two st...

Abstract

The invention discloses a multi-source compatible method for notebook onboard memory, comprising the following steps: S1. Setting up a memory mark generation circuit, the memory mark generation circuit includes a power supply terminal, a ground terminal and a plurality of mark generation nodes, each mark generation node Both can disconnect the conductive connection power supply terminal, and can disconnect the conductive connection ground terminal; S2, preset multiple sets of memory setting parameters in the basic input and output system, and each memory setting parameter corresponds to a A combination of the type of memory and the number of channels occupied by the memory; S3, the mark generation nodes in the memory mark generation circuit are respectively connected to the input and output interfaces of the central processing unit, and the central processing unit is connected to the basic input and output system. The invention realizes the compatible design of multiple memory sources at the lowest cost.

Description

technical field [0001] The invention relates to the technical field of notebook memory setting, in particular to a method for notebook onboard memory compatible with multiple sources. Background technique [0002] As a kind of computer model that is easy to carry, notebook has been deeply involved in people's life and work. An important parameter of a notebook is the memory, and the setting of the memory directly affects the storage capacity and operating speed of the notebook. At present, an important way to improve the notebook memory parameters is to realize the compatibility of multi-source memory. [0003] At present, the compatibility of multi-source memory is generally adopted to imitate the design of the memory stick, and an EEPROM (Electrically Erasable Programmable Read-Only Memory) chip is added to the motherboard, and the CPU reads the information of the EEPROM through the general-purpose input and output bus. So as to judge the memory configuration information...
