Problems solved by technology

[0002] With the development of server technology, the server has an increasing demand for expansion of memory capacity, resulting in more and more memory on the board. The number of memory in a four-way boxbore EX platform server can reach 96. If There is a memory failure during the boot process, especially on servers that need to be installed repeatedly, such as rack servers and blade servers. If a memory failure occurs, it is difficult to locate the faulty memory without fault analysis software.

Embodiment Construction

[0018] With reference to the accompanying drawings, the method of the present invention is described in detail as follows:

[0019] After the system is turned on, the system management bus on the integrated south bridge chip has started to work at this time, the BIOS will first detect the system memory, and after obtaining the memory information, send information to the CPLD through the system management bus to modify the internal registers of the CPLD ( figure 2 ), if the number of memory is N, the register size needs to be at least N bytes, and it corresponds to different bus expanders (the bus expander corresponds to the LED next to the connected memory slot one by one), so as to control the bus expander state, when register bit0=0, the corresponding bus expander output is low level; when register bit0=1, the corresponding bus expander output is high level.

[0020] When there is no memory fault, the system will set the register corresponding to the memory of the CPLD to b...

Abstract

The invention provides a hardware implementation method for rapidly positioning a fault memory. A complex programmable logic device (CPLD) which is a chip for controlling light-emitting diodes (LEDs) is connected with a system south bridge or a central possessing unit (CPU) through an inter integrated circuit (I2C), general purpose input / output (GPIO) of the CPLD which is the chip for controlling the LEDs is connected to the LEDs beside memory slots, an operation level of the CPLD which is the chip for controlling the LEDs and driving levels of the LEDs are standby power, the LEDs are close to the memory slots for arrangement during the layout of a printed circuit board (PCB), and one of the LEDs is arranged beside each slot. During the booting process of a system, when the fault memory is found, the CPLD which is the chip for controlling the LEDs is used for lighting the corresponding LED beside the corresponding slot of the fault memory, and simultaneously, during outage, the memory work information is saved into the CPLD which is the chip for controlling the LEDs.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a method for quickly locating fault memory. Background technique [0002] With the development of server technology, the server has an increasing demand for expansion of memory capacity, resulting in more and more memory on the board. The number of memory in a four-way boxbore EX platform server can reach 96. If There is a memory failure during the boot process, especially on servers that need to be installed repeatedly, such as rack servers and blade servers. If a memory failure occurs, it is difficult to locate the faulty memory without fault analysis software. Contents of the invention [0003] The purpose of the present invention is to provide a method for quickly locating fault memory. [0004] The purpose of the present invention is achieved by the following method, the LED control chip CPLD is interconnected with the system South Bridge or CPU through I2C,...
