Abstract

A system includes a programmable non-volatile memory, a switch, a control chipset, and a basic input/output (BIOS) module. The switch has a first terminal coupled to the programmable non-volatile memory, and a second terminal coupled to the control chipset. The control chipset is configured to store a SKU parameter set in the programmable non-volatile memory according to a predetermined memory allocation. The BIOS module is coupled to the control chipset, and is configured to load and update the SKU parameter set according to the predetermined memory configuration during a booting operation of the motherboard.

Claims

1. A system for configuring a motherboard, said system being connected to a remote server for receiving a SKU parameter set therefrom through a network and comprising:

a programmable non-volatile memory;

a switch that has a first terminal coupled to said programmable non-volatile memory, a second terminal, and a third terminal;

a control chipset that is coupled to said second terminal of said switch;

a baseboard management controller (BMC) that is coupled to said third terminal of said switch and said control chipset, that receives the SKU parameter set from the remote server, and that stores a predetermined memory allocation therein, wherein when an electrical connection between said first and third terminals of said switch is established, said BMC is configured to store the SKU parameter set into said programmable non-volatile memory according to the predetermined memory allocation, and wherein the SKU parameter set includes a plurality of SKU parameters for configuring the motherboard, the predetermined memory allocation includes a plurality of start addresses and a plurality of segment lengths, each one of the plurality of start addresses and the plurality of segment lengths being associated respectively with a plurality of memory segments in said programmable non-volatile memory for storing one of the plurality of SKU parameters; and

a basic input/output system (BIOS) module that is coupled to said control chipset, that stores the predetermined memory allocation therein, wherein when an electrical connection between said first and second terminals of said switch is established, said BIOS module is configured to load the SKU parameter set from said programmable non-volatile memory according to the predetermined memory allocation during a booting operation of the motherboard and to update the SKU parameter set stored therein.

2. The system of claim 1, wherein said programmable non-volatile memory is an electrically-erasable programmable read-only memory (EEPROM), and is configured to serve as a motherboard field-replaceable unit (FRU) of the motherboard.

3. The system of claim 1, wherein:

said switch further includes a control terminal coupled to said BMC; and

after said BMC writes the SKU parameter set into said programmable non-volatile memory, said BMC is configured to enable said switch to electrically connect said first terminal and said second terminal.

4. The system of claim 1, wherein:

said switch further includes a control terminal coupled to said BMC to be enabled to electrically connect said first terminal and said second terminal; and

after said BIOS module loads the SKU parameter set from said programmable non-volatile memory, said BIOS module is configured to generate a switch command and to transmit the switch command that enables said switch to electrically connect said first terminal and said third terminal.

5. The system of claim 4, wherein, said BMC is configured to:

receive the switch command from said control chipset;

enable said switch to electrically connect said first terminal and said third terminal according to the switch command;

load the SKU parameter set from said programmable non-volatile memory according to the predetermined memory allocation; and

store the SKU parameter set therein.

6. The system of claim 1, wherein the SKU parameter set received from the remote server is a user-input SKU parameter set.

7. The system of claim 1, wherein the at least one SKU parameter includes a stock keeping unit identification number, a product identification, a version code associated with versions of said BIOS module and said BMC, a chassis identification number, a chassis string, a project identification number, a banner, a table for specifying a rotation speed of a fan, or a combination thereof.
