On PCs, the BIOS (Basic Input/Output System) is updatable computer firmware designed to initialize the computer during start prior to handing control to the operating system. Due to the sensitive nature of the system settings controlled by the BIOS, a password can be set by either the computer manufacturer or the end-user. Some of the most common BIOS producers include AMI, AWARD, IBM, and Phoenix with many manufacturers making their own changes to the firmware prior to selling a computer on the open market. The common methods to reset BIOS password include: Generating a BIOS password using a hash code, entering a backdoor BIOS password, reset the BIOS password using software, reset the BIOS password using hardware, and resetting the BIOS password with vendor specific solutions. How Does the BIOS Work? The computer BIOS is the first programming code executed by a PC when the machine is rebooted or turned on.

The computer firmware conducts a power-on self-test of the system which is responsible for identifying system hardware and initializing components such as the CPU, hard drive(s), RAM, video card, mouse, and keyboard. Once the initialization task is complete, the BIOS checks the boot devices in order of configured preference (traditional default setting is the computer’s hard drive). The boot loader software is executed by the BIOS once located, and control of the computer is then passed to the operating system. Functionality that can be changed by the end-user through the BIOS user interface (UI) include setting the system clock, enabling or disabling system hardware, configuring hardware, enabling or setting passwords, and choosing the order of boot devices. Although the BIOS was originally stored on a ROM (read only memory) chip on the computer’s motherboard, today’s computers will store the firmware in flash memory or EEPROM chips that can be updated after the computer has been sold.

Once Intel started producing chips for use on non-PC hardware such as Macintoshes, a successor to the legacy BIOS system was required and is called the Extensible Interface (EFI). Although EFI provides a number of improvements over the traditional BIOS, it has not yet gained market dominance on PC’s.

Is There a BIOS on Mac OS X? Prior to the production of Mac computers using x86 or Intel chips during the later portion of the 2000’s and their use of EFI, OpenFirmware was the BIOS equivalent on all Macintosh computers. Provides similar functionality on a Mac as the BIOS and EFI do on other computing systems. It conducts tasks such as locating attached or installed hardware and uses environment variables to direct the boot process for the Mac.
