Computer Features

The following features are standard to the computer’s basic architecture.

AGP Video

An accelerated graphics port (AGP) video connector on the system board and an AGP expansion card are standard features. AGP is a bus architecture that increases video performance by routing video signals through a dedicated graphics bus rather than sending video signals on the PCI bus.

BIOS

The basic input/output system (BIOS) is software that enables your computer to communicate with peripheral devices (such as the keyboard, mouse, and monitor) without using programs on the hard drive.

The battery in your computer maintains the BIOS settings in complementary metal-oxide semiconductor (CMOS) memory even when the computer is turned off.

You can change the BIOS settings through the Setup program. Open Setup by pressing F1 when you are prompted as your computer starts.

Cache Memory

Your computer includes level 1 (L1) and level 2 (L2) cache. This cache memory is located on the processor. Cache reduces the average time required for the processor to get the data it needs from the main memory by storing recently accessed data in the cache.

Connectors

The standard input/output (I/O) connectors included with the computer are:

Keyboard port

Mouse port

Two serial ports
