Description

Method for transferring data between operating system and basic input/output system, recording medium and computer program product

The invention relates to an operating system and a basic input/output system, in particular to a method for transferring data between an operating system and a basic input/output system, a recording medium and a computer program product.

The basic input and output system (BIOS) refers to the flash memory stored on the motherboard, which contains a lot of basic input and output system platforms such as computers, tablets or smart phones. The subroutine, on the motherboard for processing software and hardware communication settings, its BIOS settings and the hardware of the system platform are related. For example, if you replace the BIOS on the motherboard of the system platform, it is likely that the system platform will not start.

The function of the BIOS is to set and control the operation of the central processing unit (CPU) and related chips, the clock and various standard peripheral device settings, such as: printer, mouse, keyboard, hard drive and soft Disc player. When the BIOS boots the system platform, it first determines if all peripherals are located and then loads the operating system into random access memory (DRAM) from a hard drive or disk drive. With this BIOS, the operating system and applications can use the BIOS to inherit the details of the input and output devices, such as network card media access control (Medium Address Control, MAC address, drive capacity and location, etc., if the device changes, simply notify the operating system or application through the BIOS change.

In the operating system phase, if you want to update the image file in the BIOS or set the key number, you may need to record some information to the BIOS via the memory space. For example, when the BIOS image file is updated during the operating system phase, the platform system executes an Update Tool to call the driver VariableRuntimeDxe to store the data in the memory space, and notifies the BIOS to update the data in the memory space for the next boot. Firmware, or when setting the key number in the operating system stage, the platform system calls the driver VariableRuntimeDxe to save the key number in the memory space, and then reads the key number in the memory space for the next time to be stored in the BIOS. The memory space in the BIOS is Variable, which can be used to transfer data between the application of the operating system and the driver of the UEFI BIOS. For details, please refer to UEFI SPEC 2.4 Version 7.1.

However, in some secure system platforms, when the platform system is in the operating system phase, the call driver VariableRuntimeDxe cannot be used to store data or information in the memory space, and the BIOS cannot be performed during the operating system phase. Update or set the information or information.

In view of the above problems, an object of the present invention is to provide a method for transferring data between an operating system and a basic input/output system, a recording medium, and a computer program product, which replace the memory space with a memory, so that it is not necessary to use the call driver VariableRuntimeDxe. The way data or information is stored in the memory space, but Data or information is transferred to the BIOS.
