  2. BIOS interrupt call - Wikipedia

    en.wikipedia.org/wiki/BIOS_interrupt_call

    BIOS interrupt calls perform hardware control or I/O functions requested by a program, return system information to the program, or do both. A key element of the purpose of BIOS calls is abstraction - the BIOS calls perform generally defined functions, and the specific details of how those functions are executed on the particular hardware of the system are encapsulated in the BIOS and hidden ...

    In the case of a hard reboot, the northbridge will direct a code fetch request to the BIOS located on the system flash memory. For a warm boot, the BIOS will be located in the proper place in RAM and the northbridge will direct the reset vector call to the RAM. In earlier PC systems, before chipsets were standard, the BIOS ROM would be located ...

  7. ACPI - Wikipedia

    en.wikipedia.org/wiki/ACPI

    Advanced Configuration and Power Interface (ACPI) is an open standard that operating systems can use to discover and configure computer hardware components, to perform power management (e.g. putting unused hardware components to sleep), auto configuration (e.g. Plug and Play and hot swapping), and status monitoring.

  8. e820 - Wikipedia

    en.wikipedia.org/wiki/E820

    e820 is shorthand for the facility by which the BIOS of an x86-based computer system reports the memory map to the operating system or boot loader. [1] It is accessed via the int 15h call, by setting the AX register to value E820 in hexadecimal. It reports which memory address ranges are usable and which are reserved for use by the BIOS. [2]
