BIOS Firmware Quiz

BIOS and Firmware

• The machine-specific part of CP/M loaded during boot time that interfaces directly with the hardware is called the BIOS.
• BIOS contents are stored in ROM chips on the motherboard in later computer systems.
• Windows XP is the version of Microsoft Windows that officially supports running on PCs which use legacy BIOS firmware.
• UEFI (Unified Extensible Firmware Interface) is the successor to the legacy PC BIOS, aiming to address its technical limitations.
• The file IO.SYS is known as the 'DOS BIOS' and contains the lower-level hardware-specific part of the operating system in MS-DOS, PC DOS, or DR-DOS.
• Compaq reverse engineered the BIOS originally proprietary to the IBM PC.
• UEFI stands for Unified Extensible Firmware Interface.
• BIOS stands for Basic Input/Output System.
• IBM divided the System BIOS into Low-Level BIOS and High-Level BIOS with the introduction of PS/2 machines.
• The BIOS was used to provide backward compatibility with existing operating systems such as DOS on the original IBM PC and XT.
• The purpose of the BIOS in a computer system is to perform hardware initialization, configure hardware components, and load the operating system.
• BIOS stands for Basic Input/Output System in computing.
• The BIOS firmware comes pre-installed on a computer system when it is manufactured.
• The function of the BIOS in modern PCs during startup is to initialize and configure the hardware components, and then boot the operating system.
• In the era of DOS, the BIOS provided a set of low-level routines that allowed the operating system and applications to interact with the hardware.
• Operating systems that do not use the BIOS interrupt calls after startup are Windows NT, Windows 2000, and Windows XP.
