2. Description of Related Art
CMOS RAM (Complementary Metal Oxide Semiconductor, Random-Access Memory) is a special type of memory that is battery-powered and installed on computer platforms, such as desktop computers, notebook computers, or network servers, for storing setup configuration data that is to be used for initialization of the computer platform at startup. Typically, the setup configuration data stored in a CMOS RAM includes current date and time (year/month/day/hour/minute/second), types of currently installed hard disk drives, memory capacity, port configuration, to name a few. When a computer platform is powered on, it will first retrieve the setup configuration data from the CMOS RAM for system initialization of the computer platform.
In the case of network servers, the end users often need to set custom-specified setup configuration data to the CMOS RAM of their network servers based on specific requirements in their network applications. However, since most end users are technically unfamiliar with CMOS RAM setting procedures, the custom-specified setup configuration data is typically set in factory by the manufacturer for the customer.
One drawback to the above-mentioned practice, however, is that when a failure occurs to the CMOS RAM or the setup configuration data stored therein is corrupted, it will cause the computer platform to be unbootable at startup; and when this happens, the customer often needs to ask the original manufacturer for help to fix the CMOS RAM problem. The process is undoubtedly quite laborious and time-consuming. Moreover, on the customer side, since the fixing of the CMOS RAM problem would typically take some time to complete on the manufacturer side, the faulted network server would be inoperable for a while until the CMOS RAM problem is fixed, which would undoubtedly affect the network services offered by the server.
It is therefore an objective of this invention to provide a computer platform setup configuration data backup handling method and system which allows a network server to be notwithstanding able to be initialized at startup in the even of a failure to the CMOS RAM, without requiring the customer to ask the manufacturer for help.
The computer platform setup configuration data backup handling method and system according to the invention is designed for use in conjunction with a computer platform of the type having a setup configuration data memory module, such as a CMOS RAM (Complementary Metal Oxide Semiconductor, Random-Access Memory) module, for providing the CMOS RAM module with a backup handling function that allows the computer platform to be notwithstanding able to be started up in the event of a failure to the CMOS RAM module.
In conception, the computer platform setup configuration data backup handling method according to the invention comprises: (1) responding to each setup configuration data setting event on the setup configuration data memory unit by duplicating a copy of setup configuration data currently stored to the setup configuration data memory unit, and then storing the duplicated copy of setup configuration data as backup data into the programmable non-volatile memory unit; (2) responding to a setup configuration data failure event on the setup configuration data memory unit at startup of the computer platform by issuing a backup enable message; and (3) responding to the backup enable message from the setup configuration data failure responding module by retrieving the backup copy of setup configuration data from the programmable non-volatile memory unit for use by the startup control unit for initialization of the computer platform.
In architecture, the computer platform setup configuration data backup handling system according to the invention comprises: (A) a setup configuration data backup module, which is capable of responding to each setup configuration data setting event on the setup configuration data memory unit by duplicating a copy of setup configuration data currently stored to the setup configuration data memory unit and then storing the duplicated copy of setup configuration data as backup data into the programmable non-volatile memory unit; (B) a setup configuration data failure responding module, which is capable of responding to a setup configuration data failure event on the setup configuration data memory unit at startup of the computer platform by issuing a backup enable message; and (C) a backup data retrieving module, which is capable of responding to the backup enable message from the setup configuration data failure responding module by retrieving the backup copy of setup configuration data from the programmable non-volatile memory unit for use by the startup control unit for initialization of the computer platform.
The computer platform setup configuration data backup handling method and system according to the invention is characterized by the capability of making a backup copy of the setup configuration data stored in the CMOS RAM and storing the backup data in a programmable non-volatile memory unit, such that in the event of a failure to the CMOS RAM, the backup copy of setup configuration data can be retrieved from the programmable non-volatile memory unit for initialization of the computer platform at startup. This feature allows the computer platform to be notwithstanding able to start up in the event of a failure to the CMOS RAM, without requiring the end user to ask for help from the manufacturer.
The invention can be more fully understood by reading the following detailed description of the preferred embodiments, with reference made to the accompanying drawings, wherein:
The computer platform setup configuration data backup handling method and system according to the invention is disclosed in full details by way of preferred embodiments in the following with reference to the accompanying drawings.
In actual application, the computer platform setup configuration data backup handling system of the invention 100 is capable of allowing the computer platform 10 to be notwithstanding able to boot up in the event of a failure to the CMOS RAM module 30.
As shown in
Firstly, the respective attributes and behaviors of these constituent components 110, 120, 130 of the computer platform setup configuration data backup handling system of the invention 100 are described in details in the following
The setup configuration data backup module 110 is capable of responding to each setup configuration data setting event 201 on the CMOS RAM module 30 (i.e., in the event of a set of setup configuration data being set by the manufacturer or user to the CMOS RAM module 30) by duplicating a copy of the setup configuration data currently stored to the CMOS RAM module 30 and then storing the duplicated copy of setup configuration data as backup data into a predefined storage area 51 (hereinafter referred to as “backup setup configuration data storage area” and denoted by ROM-CMOS) in the programmable non-volatile memory unit 50. In practical implementation, for example, the programmable non-volatile memory unit 50 can be either a flash memory module used for storing BIOS code (a memory space of the BIOS module 40) or a separate flash memory unit appended to the BIOS module 40.
The setup configuration data failure responding module 120 is capable of responding to a setup configuration data failure event 202 on the CMOS RAM module 30 (i.e., in the event of a failure to the CMOS RAM module 30) at startup of the computer platform 10 by issuing a backup enable message to the backup data retrieving module 130.
The backup data retrieving module 130 is capable of responding to the backup enable message from the setup configuration data failure responding module 120 by retrieving the backup copy of setup configuration data stored in the ROM-CMOS area 51 of the programmable non-volatile memory unit 50 for use by the BIOS module 40 for initialization of the computer platform 10.
The following is a detailed description of a practical application example of the computer platform setup configuration data backup handling system of the invention 100 during actual operation.
Referring to
Afterwards, whenever the computer platform 10 is powered on, if the setup configuration data stored in the CMOS RAM module 30 is uncorrupted and good for use, the BIOS module 40 will retrieve the setup configuration data from the CMOS RAM module 30 for initialization of the computer platform 10.
On the other hand, if the setup configuration data stored in the CMOS RAM module 30 is corrupted (i.e., a setup configuration data failure event 202 occurs), it will cause the setup configuration data failure responding module 120 to respond by issuing a backup enable message to the backup data retrieving module 130, thereby activating the backup data retrieving module 130 to retrieve the backup copy of setup configuration data stored in the ROM-CMOS area 51 of the programmable non-volatile memory unit 50 for use by the BIOS module 40 for initialization of the computer platform 10. This allows the computer platform 10 to be notwithstanding able to start up successfully even though the setup configuration data stored in the CMOS RAM module 30 is corrupted.
During the foregoing procedure, if the backup setup configuration data stored in the ROM-CMOS area 51 or the programmable non-volatile memory unit 50 is also corrupted, then the BIOS module 40 can nevertheless utilize a default set of setup configuration data stored elsewhere for the initialization of the computer platform 10 at startup.
In conclusion, the invention provides a computer platform setup configuration data backup handling method and system for use with a computer platform for providing the computer platform with a setup configuration data backup handling function, which is characterized by the capability of making a backup copy of the setup configuration data stored in the CMOS RAM and storing the backup data in a programmable non-volatile memory unit, such that in the event of a failure to the CMOS RAM, the backup copy of setup configuration data can be retrieved from the programmable non-volatile memory unit for initialization of the computer platform at startup. This feature allows the computer platform to be notwithstanding able to start up in the event of a failure to the CMOS RAM, without requiring the end user to ask for help from the manufacturer. The invention is therefore more advantageous to use than the prior art.
