The BIOS in modern PCs initializes and tests the system hardware components, and loads a boot loader from a mass storage device which then initializes an operating system. More recent operating systems do not use the BIOS interrupt calls after startup. Most BIOS implementations are specifically designed to work with a particular computer or motherboard model, by interfacing with various devices especially system chipset. In modern computer systems, the BIOS contents are stored on flash memory so it can be rewritten without removing the chip from the motherboard. This allows easy, end-user updates to the BIOS firmware so new features can be added or bugs can be fixed, but it also creates a possibility for the computer to become infected with BIOS rootkits.

Saturation diving is diving for periods long enough to bring all tissues into equilibrium with the partial pressures of the inert components of the breathing gas. It is a diving technique that allows divers working at great depths to reduce time spent undergoing decompression. A diver breathing pressurized gas accumulates dissolved nitrogen in his or her tissues, which can cause decompression sickness "the bends" if permitted to come out of solution too quickly; hence, returning to the surface safely requires lengthy decompression. Once the dissolved gases in a diver's tissues reach the saturation point, however, decompression time does not increase with further exposure.
