Embodiment Construction

[0022] According to an embodiment of the present invention, a memory management method is provided.

[0023] Such as figure 1 As shown, the memory management method according to the embodiment of the present invention includes:

[0024] Step S101, the computer system runs and enters the EFI environment;

[0025] Step S103, obtain the parameter information of internal memory from motherboard under EFI environment, read the serial presence detection (SPD) information of internal memory from system management bus (SMBus), use SPD information and from the desktop management interface that is used to collect computer system information (DMI) Compare the obtained DMI information to determine whether the memory status is normal.

[0026] The method may further include: obtaining memory troubleshooting (debug) information. Wherein, the debug information may include: a CPU data segment and a chipset data segment required for troubleshooting.

[0027] In addition, before step S103 i...

Abstract

The invention discloses an internal memory management method and a device. The method comprises the following steps that: step S101, a computer system operates and enters an extensible firmware interface (EFI) environment; step S103, parameter information of an internal memory is obtained from a main board in the EFI environment, serial presence detection (SPD) information of the internal memory is read from a system management bus, and the SPD information is compared with a directional memory interface (DMI) information obtained by a DMI used for collecting computer system information for judging whether the internal memory state is normal or not. The parameter information and the SPD data are read in the EFI environment, in addition, whether the internal memory is normal or not is judged according to the tabletop management interface information, so the internal information management and the internal memory fault diagnosis are realized in the EFI environment, a UEFI BIOS main board can be supported, and simultaneously, rich internal information obtaining and accurate fault diagnosis are realized, so the method and the device help engineers to do operation relevant to the internal memory.

Description

technical field [0001] The present invention relates to the field of computers, and in particular, to a memory management method and device. Background technique [0002] In the current computer system, some tools in the traditional DOS environment can also realize memory information management and fault diagnosis. However, these tools can only be used in the original DOS environment, and the current Basic Input Output System (BIOS) has developed from the traditional BIOS to the Unified Extensible Firmware Interface (UEFI) BIOS, and the traditional The tools under DOS cannot be applied to UEFI BIOS; and, when using memory information management and fault diagnosis under DOS environment, it is usually necessary to connect external devices, and this device must be formatted in DOS boot mode, so the hardware The requirements are high and not easy to realize. [0003] In the current UEFI Shell environment, the tools used for development are relatively simple, but the functions...
