the system's components, such as the operating system, memory, peripheral devices, expansion cards, and asset tag. Information about the

system's components is displayed as a MIF file or through the Dell Inspector program.

DMTF

Distributed Management Task Force. A consortium of companies representing hardware and software providers, of which Dell Computer

Corporation is a member.

dpi

dots per inch

DPMS

Display Power Management Signaling. A standard developed by the Video Electronics Standards Association (VESA) that defines the hardware

signals sent by a video controller to activate power management states in a monitor. A monitor is said to be DPMS-compliant when it is designed

to enter a power management state after receiving the appropriate signal from a computer's video controller.

DRAM

dynamic random-access memory. A computer's RAM is usually made up entirely of DRAM chips. Because DRAM chips cannot store an electrical

charge indefinitely, your computer continually refreshes each DRAM chip in the computer.

drive-type number

Your computer can recognize a number of specific hard-disk drives. Each is assigned a drive-type number that is stored in NVRAM. The hard-disk

drive(s) specified in your computer's System Setup program must match the actual drive(s) installed in the computer. The System Setup program

also allows you to specify physical parameters (logical cylinders, logical heads, cylinder number, and logical sectors per pack) for drives not

included in the table of drive types stored in NVRAM.

DSP

digital signal processing

DTE

data terminal equipment. Any device, such as a computer system, that can send data in digital form by means of a cable or communications line.

The DTE is connected to the cable or communications line through a data communications equipment (DCE) device such as a modem.

ECC

error checking and correction

ECP

Extended Capabilities Port

EEPROM

electrically erasable programmable read-only memory

EIDE

enhanced integrated drive electronics. EIDE devices add one or more of the following enhancements to the traditional IDE standard:

l Data transfer rates of up to 16 MB/sec

l Support for drives other than just hard-disk drives, such as CD-ROM and tape drives

l Support for hard-disk drives with capacities greater than 528 MB

l Support for up to two controllers, each with up to two devices attached

EISA

Extended Industry-Standard Architecture, a 32-bit expansion-bus design. The expansion-card connectors in an EISA computer are also

compatible with 8- or 16-bit ISA expansion cards.

To avoid a configuration conflict when installing an EISA expansion card, you must use the EISA Configuration Utility. This utility allows you to

specify which expansion slot contains the card and obtains information about the card's required system resources from a corresponding EISA

configuration file.
