Computer system with built-in flash memory backup operation unit and method thereof

The present invention relates to a computer system and method for building a flash memory backup operation unit for a flash memory operation unit, in particular a computer built in three or more operation units, at least one of which is a hard disk. At least two of the machine working units are flash memory working units, and the two flash memory working devices have the same data content and are mutually redundant.

According to the personal computer, the hard disk drive is used as the loading device of the operating system. In recent years, due to the rapid development of semiconductor flash memory (Generally used NAND type), some portable personal computers have been replaced with flash. Memory to replace the hard drive. However, due to the high cost per unit of memory, it is not economical or practical to replace the hard disk drive with flash memory. If the capacity is too small, it is not convenient to use. Furthermore, the computer virus is awkward, and when the flash memory is damaged, the user has to spend several hours reinstalling.

However, compared with the flash memory operating device, the hard disk drive has many disadvantages including large power consumption and noise, etc., but the biggest fatal disadvantage is its stability, the spindle motor of the two-and-a-half-semi-hard disk drive. Generally, there are 5400 rpm (5,400 laps per minute) or 7200 rpm. Under high-speed rotation, it is easy to be damaged by external collision and vibration. Once the track is damaged, the data recorded on the track is easily damaged in whole or in part. This has been the biggest pain for computer users.

Second, the flash memory operating device, the main advantage is fast and no noise (because no motor), but the disadvantage is that the capacity is too small, the current single flash memory capacity is about 8GB or 16GB, therefore, to achieve 640GB capacity requires 40 flash memory.

The power of the unselected working unit is turned off. For example, in the preferred embodiment, the first flash memory operating unit 6000 is selected as the power-on executing device, and the power is turned on, the second flash memory working unit 7000 and the hard The power of the disc drive unit 5000 is turned off.

The foregoing switch control unit 4000 controls the power of each work unit to be turned on or off, so that the virus cannot invade the work unit whose power is off, and only the power of the work unit as the booting device is turned on, and the power of the remaining work units is turned off. The conventional computer system saves power, and the operating unit that is powered off is not operating to reduce the heat energy in the computer system.

Referring to Figures 1, 3 and 4, the backup method of the present invention will be described in detail. The method comprises the following steps: S100 starts, and the computer system is started.

The S200 detects the operating unit, and the basic input/output system (BIOS) 3000 detects the number of working units and the operating system 10 in each working unit when performing a Power On Self Test (POST) of the computer system. If yes, proceed to step 400, otherwise proceed to step 300.

In a preferred embodiment of the present invention, the basic input/output system (BIOS) 3000 detects a hard disk drive unit 5000 and the first flash memory 6000 and the second flash memory 7000.

The S300 is copied. In the first booting of the present invention, only the hard disk drive unit 5000 has an operating system and an application (including a control module) and data, and the first flash memory working unit 6000 and the second flash memory working unit The 7000 is empty content, so the basic input/output system (BIOS) 3000 loads the operating system 10 in the hard disk drive unit 5000 into the dynamic random access memory 2000, that is, the hard disk drive unit 5000 is powered on. Executing the device and copying the operating system 10 and the application program (including the control module) and the data therein to the first flash memory working unit 6000 and the second flash memory in the operating system of the hard disk drive unit 5000 Inside the body working unit 7000.

After the completion of this step, the hard disk drive unit 5000 and the first flash memory working unit 6000 and the second flash memory working unit 7000 become compatible working devices, and go to step 600 in the hard disk drive unit 5000. The operating system 10 performs general operations or shuts down.

The S400 selects a flash memory as the booting execution device. In this step, the basic input/output system (BIOS) 3000 detects that the first flash memory operating unit 6000 and the second flash memory working unit 7000 have the operating system 10 therein. And using the control module 20 in the basic input/output unit (BIOS) 3000 to select two flash memory working units 6000, one of which is a booting execution device, and close another flash memory working unit and a hard disk drive The power of the work unit 5000, and when the power-on execution device cannot be executed or damaged, is immediately executed by the backup device.

S410 selects the first flash memory working unit 6000 as the booting execution device, and the second flash memory working unit 7000 is the backup device, and the basic input/output system (BIOS) 3000 will be the first flash memory working unit 6000. The internal operating system 10 is loaded into the dynamic random access memory 2000. (as shown in Figure 1 computer system implementation)

In addition, in this step, the switch control unit 4000 turns on the power of the first flash memory working unit 6000, and turns off the power of the second flash memory working unit 7000 and the hard disk working unit 5000.

S420 selects the second flash memory working unit 7000 as the booting execution device, the first flash memory working unit 6000 is the backup device, and the basic input/output system (BIOS) 3000 will be the second flash memory working unit. The operating system 10 within the 7000 is loaded into the dynamic random access memory 2000. (as shown in Figure 1 computer system implementation)

In addition, in this step, the switch control unit 4000 turns on the power of the second flash memory working unit 7000, and turns off the power of the first flash memory working unit 6000 and the hard disk working unit 5000.

The S500 performs the synchronous update of the contents of all the work units, and reformats another flash memory unit and copies the data. In this step, the following steps are performed: the S501 control module 20 turns on the backup device and/or the hard disk drive. The power of the working unit 5000 (for example, step 410 is the second flash memory working unit 7000 and/or the hard disk working unit 5000; step 420 is the first flash memory working unit 6000 and/or the hard disk working unit 5000 And knowing the operating system 10; S502 synchronously updating the backup device and/or the hard disk drive unit 5000 content; S503 is damaged or unexecutable in the operating system 10 of the booting execution device, and the operating system of the backup device is loaded (ie, After the boot device is turned on, the boot device is formatted, and the operating system and the application program and data in the backup device are copied to the boot device; S504 turns off the power of the unoperated work unit. The operating system 10 is also known.

The S600 performs general operations or shuts down.

In summary, the present invention has the following advantages:

1. One of the two flash memory operating units 6000, 7000 is used as the booting device as a backup device, which can achieve a quick reply. When the booting device is damaged, it can be used by the backup device within three seconds. The power-on is replaced by the boot-up device and the operating system is reformatted and copied immediately to the corrupted flash memory unit.

2. Under normal use, the power of the working unit as the power-on execution device is turned on, and the power of the remaining working unit is turned off, which can save power generation and heat generation of the machine operation, and prevent virus intrusion.

3. The hard disk drive unit 5000 is only used as a large-capacity data and file storage device. It is usually not turned on, so it can reduce the risk of damage caused by vibration and collision, and also cut off the chance of being damaged by virus invasion.
