BIOS (Basic Input/Output System)
BIOS is a set of routines that affect how the computer transfers data between computer components,
such as memory, disks, and the display adapter. The BIOS instructions are built into the computer’s
read-only memory. BIOS parameters can be configured by the user through the BIOS Setup program.
The BIOS can be updated using the provided utility to copy a new BIOS file into the EEPROM.
Bit (Binary Digit)
Represents the smallest unit of data used by the computer. A bit can have one of two values: 0 or 1.
Boot
Boot means to start the computer operating system by loading it into system memory. When the manual
instructs you to “boot” your system (or computer), it means to turn ON your computer. “Reboot” means
to restart your computer. When using Windows 95 or later, selecting “Restart” from “Start | Shut Down...”
will reboot your computer.
Bus Master IDE
PIO (Programmable I/O) IDE requires that the CPU be involved in IDE access and waiting for me-
chanical events. Bus master IDE transfers data to/from the memory without interrupting the CPU. Bus
master IDE driver and bus master IDE hard disk drives are required to support bus master IDE mode.
