8.1 BIOS
The basic input/output system (BIOS) is the most basic software loaded to a computer
hardware system. It provides an abstraction layer between the computer hardware and the OS.
It is used to perform hardware initialization during the boot process and provide runtime
services for the OS and programs. Figure 8-1 shows the BIOS position in the system.
The BIOS data is stored on the Serial Peripheral Interface (SPI) flash memory. The BIOS
performs a power-on self-test (POST), initializes CPU and memory, checks the I/O and boot
device, and finally boots the OS. The BIOS also supports the advanced configuration and
power interface (ACPI) and hot swap setting.
Huawei Kunpeng 920 platform server is a patented BIOS product with independent
intellectual property rights. It supports customization and provides a variety of in-band and
out-of-band configuration functions as well as high scalability.
