PCI/PNP ISA IRQ Resource Exclusion
This sub menu allows you to reserve specific IRQ(s) for use by
legacy devices and indicates if the IRQ has been assigned.
By default, all IRQ lines are set to [Available], which means they
are “available” to the PCI/PNP resource pool. At power up, the
BIOS assigns IRQs from this pool as required to the on-board PCI
devices (VGA controller, network controller, IDE controller, and
USB controller), as well as the system board COM and LPT ports.
If you install a legacy ISA such as a multi-port serial card that
requires one or more interrupts , set those IRQ lines to [Reserved] to
prevent the BIOS from assigning them to PCI devices.
If the message “Indicates a DMA, interrupt, I/O, or memory
resource conflict with another device” appears when you select
[Reserved], that IRQ has been assigned to a device in the pool. If
the message does not appear, it means the IRQ is available.
Once you know what resources are available , set the board jumpers
and set those IRQ lines to [Reserved].
I/O Device Configuration
This sub-menu allows enable/disable and manually configure the
on-board COM and LPT ports, as well as enable the floppy disk
controller.
Serial port A:
This selection configures the rear panel DB9 serial connector.
The Default setting is “Auto” which allows the BIOS to
determine the settings. Select “Disabled” to turn off the port
and use the resources elsewhere. Select “Manual”, to allocate
the resources manually. When you select a Manual
configuration, you must enter the following values.
Base I/O address:
The Base IO Address determines the COM port designation
with three available selections. 3F8 corresponds to COM1,
3E8 corresponds to COM3 and 2E8 corresponds to COM4.
Note: I/O address 2F8 (COM2) is reserved for the
touchscreen controller.

point-of-sale functionality including such items as an integral mag
card reader, customer display, and cash drawer interfaces among
others. A Software Developers Kit is available that provides the
software and documentation required to leverage these unique
features for third party applications.
Like any personal computer, the PC Workstation is changing to
keep up with advances in processor, memory, and LCD technology.
The Ultra system board represents the latest development.
To continue our description, the MICROS PCWS (PC Workstation)
can be viewed from three dimensions: Profile, Display, and System
Board, detailed in the following pages.

Contents
Profile
Low Profile and Adjustable Display Case
All PC Workstations are available in a Low Profile (LPs), or
Adjustable Display Sharp (ADs) case style. The AD case can use a
variety of 11.3” and 12.1” active and passive LCD panels. The LP
case does not support 12.1” LCD panels. Figure 1-1 shows an
example of the LPs (left) or ADs (right) casework.

Display and Touchscreen
PC Workstations support a variety of backlit active and passive
matrix LCD panels. The display is closely integrated with a highly
reliable, 5-wire t ouchscreen panel which c an replace the t raditional
mouse or other pointing devices.
The AD and LP casework influences the size of the LCD. The Low
Profile case supports only 11.3” LCDs. The AD case supports both
11.3” and 12.1” LCD panels. The Ultra system board adds support
for a 12.1” passive LCD.
Both the LP case, and the Sharp 11.3” passive LCD goes end-of-life
in mid 1999.
System Boards
With the introduction of the Ultra System Board, there are now
four PCWS System Boards in the field. A brief description of each
follows. These system boards can be installed in either the LP or
AD case.
The System
What is the PC Workstation?
Model 32R and 32L
The Model 32R and 32L system boards represent the 486/586
processor class. These system boards set the standards for those
that follow.

Diagnostics Utilities
There are two versions of diagnostics utilities designed to test the
POS extensions of the Ultra PC Workstation. The first,
WorkStation Diagnostics Te st (WSDT), is intended for the DOS or
Windows 95/98 command mode environments. Once installed on a
bootable floppy diskette, WSDT forms a complete stand-alone
diagnostics utility, used primarily to confirm basic functionality of
the workstation POS extensions.
The second version, DEMODIAG, runs in the Windows 95/98 and
Windows NT environments . Eac h diagnostics utility all ows you test
the LCD, backlight, mag stripe reader, customer display(s), and
other ports. Please note that neither diagnostics utility is intended
to replace off-the-shelf PC diagnostics utilities that test PC
functions such as memory, hard disk, and the processor.
Both diagnostics utilities are available in the hardware support
section of the MICROS web site, www.micros.com.
PCWS API
The PCWS Application Programming Interface (API) is a set of
services that resides between the application and oper ating system
(Windows 95/98 or Windows NT) and the unique POS hardware on
the system board. This allows the application programmer to use a
standard set of API calls to access such POS features as LCD
contrast, mag stripe data, and the cash drawers.

Care and Handling
Environmental Requirements
T o ensure proper operation of the equipment, consider the following
guidelines for placement of the PC Workstation.
Dimensional data for each workstation case and accessories can be
found in Appendix A of this manual. Before you decide on the space
each device should occupy, take measurements and compare them
to ours.
Location
Tile is the recommended floor surface for areas surrounding the
workstation. If the floor covering adjacent to the equipment is
carpeted, an anti-static grade is recommended. If the carpeting
surrounding the area containing the equipment is not composed of
anti-static material, the use of static-discharge mats should be
considered. The recommended type of anti-static mat is one that
incorporates a grounding clip with a cable to provide a disch a rge
path to ground.

Foreign Materials
WARNING:
Do not use sharp objects such as a pen or pencil to
press keys on the touchscreen as this could damage t he
sensing layer.
Liquid spillage can cause damage to the circuits in the
unit. Do not place the equi pment near food prep eration
areas, disk racks, or water stations. The PCWS
includes a gasket seal around the touchscreen which
may afford some protection from liquid spillage. Also,
the mag card reader assembly is mounted to a tray
that is designed to prevent liquid spills from reaching
the system board.
If any type of liquid is spilled onto the touchscreen or
mag card reader slot, turn off power as quickly as
possible and remove the spillage. Do not power-up the
unit until it has been determined that no spillage
remains inside the unit.

Cleaning
The System
Care and Handling
Electrostatic Discharge (ESD)
The occurrence of electrostatic discharge (ESD) usually takes the
form of a discharge from the operator’s hand to cash drawers, the
workstation, or other peripherals connected to the workstation.
ESD is more common in the dry climates during the winter, and
less common in the moist climates. The PCWS has good built- in
immunity to ESD in most environments. However, tile or anti-static
carpet should still be employed in the area near the workstation.
Temperature and Humidity
The continuous operating temperature for the PCWS is between
40°F and 113°F (5°C to 45°C). A constant humidity between 40%
and 90% is desired for proper operation of the equipment.
WARNING:
Always use a chamois or clean lint-free clo th to clean
the PCWS cabinet and touchscreen surface . Do not use
chemical, alcohol, or petro leum based cleaners that are
not recommended for plas tics.
Depending on how much they are used, floppy drives,
mag card readers and tape backup drives require
periodic cleaning. Cleaning kits are available from a
variety of sources. Be sure to follow the instructions
supplied with the cleaning kits.
Transporting the Workstation
If a hard disk is installed, always power down the workstation
before transporting it, even if you are just moving it across your
work surface. The high density hard drives used today are more
susceptible to damage if subjected to a sudden physical shock while
they are operating, especially if the heads happen to be reading or
writing to the disk surface. Powering off the workstation
automatically parks the heads, allowing you to move the unit
without risking damage to the hard disk.

board adds support for a 12.1” STN LCD panel installed in the AD
case. LCD panels are configured through a system board DIP
Switch and jumper setting.
Configuration and Control Registers
The Configuration and Control Registers perform the majority of
the Ultra POS related functions. It is composed of U23, a
EPF6016A144 Programmable Logic Device from Altera, a more
advanced version of the AMD MACH part used on previous system
boards. In addition to the programmable IO pins and registers , this
device adds two UARTs.
Touchscreen Controller
The Ultra system board uses the same Elo Graphics Touchscreen
Controller and 5-wire touch panel as the Model 32 and Model 64
workstations. The touchscreen controller communicates to the
system board through COM2.
PCI Ethernet Interface
The Ultra Ethernet interface is based on an AMD 79C970 PCI
based Ethernet controller. The workstation includes a rear panel
10BaseT modular connector.

Spread Spectrum Clock Generator
A typical Pentium based system board produces clock pulses with
rise times that result in greater higher-order harmonic energy than
those in previous designs. Spre ad spectrum clocking modulates the
clock signal’s frequency at a 50 KHz rate, spreading the energy of
the clock fundamental to minimize energy peaks at harmonic
frequencies. The clock signal radiates the same amount of energy,
but is spread across a wider range of frequencies without affec ting
the rise and fall times.
Spread spectrum clocking ensures t he Ultra system board will more
readily comply with EMI standards while at the same time greatly
reducing the number of passive components required for EMI
suppression. This, combine d wi th the SiS 5581 core logic device,
reduces number of system board layers from ten to six, increasing
reliability.
Serial/Parallel Ports
PCWS Ultra Hardware Configuration
What’s Inside?
The Ultra system board includes two high-speed serial ports and
one enhanced parallel port. One RS232 Port is based on the
industry standard DB9 connector an d is backed by a 16550 buffer ed
UART.
The second port, also based on the 16550 device, can provide either
an RS422 or RS232 interface via a rear panel 8-pin modular
connector. In RS232 mode, this port supports simple TX/RX
interface lacking hardware hand-shaking support.
In RS422 mode, when used with certain MICROS applications , t his
port is designed to support MICROS IDN devices. The function of
this port is controlled by application soft ware or through the Setup
Utility.

PCWS Ultra Hardware Configuration
Processor
The PCWS Ultra system board currently supports the Intel Classic
Pentium
speeds up to 233 MHz. Support has now been added for AMD K6-2/
300 and K6-2/400.
®
(P54C) and Pentium with MMX Processors (P55C) at
WARNING
Never operate the Ultra system board without the
processor heatsink and air duct/fan assembly install ed
and the fan operating.
STATIC SENSITIVE DEVICES
Follow ESD Procedures when replacing or upgrading
the processor.
Processor Configuration Jumpers
Intel and AMD processors utilize a fractional bus operation where
the incoming bus frequency is multiplied to set the processor core
operating frequency. This allows the processor core to operate at
higher frequency while communicating to the system bus running
at a lower frequency.
JP6 sets the bus multiplier input to the processor and JP4
determines the processor supply voltage. For example, the P54C
“classic” Pentium processor requires a supply voltage of +3.54V,
while the Pentium MMX requires +2.84V. Note the alternative
setting for the AMD K6-2/233MHz through K6-2/366MHz. The
alternate setting may be required f or stable operati on due to power
supply tolerances.
JP4 presents a 5-bit binary input to a programmable voltage
regulator, known as the VCORE regulator.
Settings for JP4 and JP6 can be found in Figure 3-16.
AMD Processor Note:
To fully support the AMD K6-2 processors, BIOS
Version 1.00d or later is required. BIOS versions prior
to 1.00d will report an AMD K5 processor is installed,
and does not report the operating speed.

Processor Heat Sink and Air Duct Assembly
The processor is mounted in a 321-pin Zero Insertion Force (ZIF)
Socket 7 compatible socket. The processor heat sink assembly
consists of the heat sink itself, the clip which fastens it to the
processor socket, and a thermal pad between the heat sink and
processor.
The fan is mounted to sheet metal which is formed into a threesided air-duc t or channel. The air duct is attached to the processor
heat sink and fits over the power supply heatsink, and rear fan
shroud. The heatsink is attached to the processor socket by a clip,
with a hinge at one end. A thermal pad is mounted to the bottom of
the heat sink. Heat sink compound is currently not used.
The fan pulls fresh air in through the gap between the base and the
lid, moves it across the processor heat sink, through the air duct,
and out through a shroud at the rear of the base. The shroud is the
same as used in previous workstations, but a fan is not installed.

Main Memory
The PCWS Ultra system board main memory consists of single
Dual-In-Line-Memory-Module (DIMM) socket. A DIMM is roughly
the same as a pair of SIMMs connected end-to-end. DIMMs have
been replacing SIMMs in most desktop and tower PCs in the last
few years, and therefore have become inexpensive and readily
available.
The table below shows the available configurations. The Ultra
BIOS and chip set will automatically detect and size the DIMM.

The Ultra system board is designed to use 168-pin, +3.3V,
unbuffered 100MHz Synchronous DRAM (SDRAM) DIMMs. Like
the SIMMs used on the M32 and M64 system boards, the DIMM
must be less than 1 inch in height. Standard PC100 SDRAMs are
taller than 1 inch, preventing the top cover from installing pro perly.

Follow ESD procedures when handling the hard disk.
Requirements
❏ PCWS Hard Drive Kit, available with or without Windows 95 or
Windows NT pre-loaded.
❏ PC Compatible keyboard
❏ PCWS Floppy Diskette.
Procedure:
1. Carefully remove the hard disk and mounting bracket from it’s
packing material.
1st Page Content s
2. If you are installing a hard drive kit from MICROS, you can
skip this step. Otherwise, check the drive select jumpers.
❏
All IDE drives include a set of jumpers that designate one of
several configurations including “master”, “slave”, “single”,
or “cable select”. The master, slave, or cable select settings
are required when two drives share a common interface
cable.
In a single drive installation such as the PCWS, this jumper
must be set to “single”. When you purchase a new drive from
MICROS or elsewhere, this is the default setting.
However, should you “borrow” a hard disk from a desktop
PC with two hard drives installed, one drive will be
configured as a “master” and the other as a “slave”. In some
cases, the cable select function may be used. None of these
settings will function in the PCWS. Consult the
documentation supplied with the hard drive for the jumper
settings of a single hard drive installation.
3. Power off and remove the LPs or ADs cover.
4. If you are not installing a kit from MICROS, make sure you are
using the correct hard disk bracket. Figure 3-20.

Expansion Card Installation
Expansion Card Installation
This section provides an overview of Plug and Play, describes the
Ultra PCI/ISA Riser Card, and provides instructi ons for installing a
PCI or ISA expansion card.
Plug and Play
The following information is not intended to repeat the details of
the Plug and Play specification, but merely to pr ovide an overview
of its operational concepts and how they affect you, the installer
adding peripheral ca rds to the PC workst ation . It a lso import ant t o
note that at the time this Setup Guide was written, true Plug and
Play compatibility was available only on the Windows
operating system.
Plug and Play (PNP) is aimed at one of the shortcomings of the
open and extensible architecture of the AT class personal
computers: management and allocation of system resources such as
IO Ports, interrupt requests lines, DMA requests lines, etc. These
resources are in limited supply but are required for almost all
peripheral add on cards. As more add-on cards are added to the AT
bus, the possibility of device conflicts increases because in most
cases, these resources cannot be shared.
1st Page Content s
®
95 or 98
Although the pool of resources is finite, it is still quite extensive.
This is why it makes sense to manage them more efficie ntly than to
simply add more. In fact, the Peripheral Component Interconnect
(PCI) bus represents a step towards better management of
resources at the BIOS and chipset level, but does not include the
operating system. The PCI bus maintains its own set of internal
interrupts associated with each PCI card or system board device . T o
manage these resources, they are combined and placed in a PCI/
PNP “resource pool” where they can be assigned as needed to PCI
or Plug and Play devices.
Legacy ISA Card
The term Legacy ISA card is used to denote older ISA bus cards
that do not conform to PNP specifications. To install these cards,
the technician must know the resource requirements of the card as
well as what resources are available. Configuration of these cards is
typically performed by setting DIP switches to decode IO port
addresses and or setting jumpers to steer IRQ and DMA request
lines to the proper bus pins. Legacy ISA cards may also be
configured by a softw are utili ty. Still , the in staller must kno w what
resources are available and enter them into the configuration
software.
3-34
1st Page Contents
Plug and Play spreads the burden of resource management
between the BIOS and chip set, the operating system, and the
manufacturer of the add-in card or chip.
With PNP, the installer simply plugs in the card, turns on the PC,
and lets the BIOS, chipset, and operating system determine the
resource requirements, then assign them.
Thus, the PNP compatible BIOS assumes the role of resource
manager. It is responsible for configuring PNP cards and system
board devices during the Power On Self Test. Once the POST is
complete, and the operating system starts up, it becomes
responsible for managing PNP devices with the BIOS providing
run-time services for the operating system.

Expansion Board Configuration
Depending on the type of card you installed, you may have to enter
the Setup Utility and configure it.
Legacy ISA Card
If you installed a legacy ISA card, for each IRQ line it requires,
you must reserve an IRQ in the “PNP/PCI IRQ Resource Pool
Exclusion” screen of the Setup Utility.
The primary question when installing a legacy ISA card is
“what IRQs are available for use with this card?” One way to
find out is to change each IRQ from [Available] to [Reserved] in
the IRQ Resource Pool Exclusion scree n. The BIOS will report if
the IRQ has been assigned to a PCI/PNP device and is not
available for a legacy ISA card. If you are running Windows
95, 98, or NT, you can also see the IRQ assignments through the
control panel.
By default, IRQ3, IRQ4, and IRQ7 are assigned to the system
board COM and LPT Ports. IRQ10 is assigned to the AMD
Ethernet controller. IRQ12 is assigned to the PS/2 Mouse.
IRQ14 is assigned to the primary IDE channel. Otherwise, the
remaining IRQ lines should be available for the legacy ISA card.

Should you need to remove an IRQ line from the PnP/PCI
resource pool, proceed as described below.
❏ Power-up the workstation and enter the Setup Utility by
pressing [F2] when prompted
❏ Use the right cursor key to select the Advanced Menu
❏ Cursor down to the “PCI/PnP ISA IRQ Resource Exclusion”
field and press [Enter]
By default, all IRQ resources are made “available” to the
PNP/PCI resource pool
❏ Cursor down to the IRQ line you wish to reserve for the
legacy ISA card and press the [-] key to select [Reserved]
If the message “Indicates a DMA, interrupt, I/O, or memory
resource conflict with another device” appears when you
attempt to reserve an IRQ, it means the IRQ line has been
assigned to a PnP or PCI device by the BIOS. Try another
IRQ line.

Figure 4-1: Ultra System Board Diagnostics LEDs
When DS1 is ON , this is an in dication t hat the Over Voltage Protection
(OVP) circuit has shut down the on-board power supply.
❏ This condition occurs should the +5V output become shorted to a
higher voltage such as +12V. This could be the result of a
component failure in the power supply, or through a foreign object/
spillage on the system board.
D12, D13, D16 and D17 are part of the 10BaseT interface and have the
following functions.
❏ D17 is active when the interface is transmitting data.
❏ D12 is active if the cable transmit and receive polarity is reversed.
The polarity check function is active after a reset or Link Fail. See
the explanation for D13. The controller has the ability to inver t the
polarity of the signal appearing on the RXD+/- pair if the polarity of
the received signal should be reversed due to an improperly wired
connector.
1st Page Contents
❏ D16 is active when the interface is receiving data.
❏ D13 is active when the interface has a good link status.
When the transmit pair is inactive, “link beat pulses” are
periodically sent over the twisted pair cable by all devices to
monitor cable integrity.
The absence of link beat pulses and receive data on the RXD+/- pair
will cause the controller to enter the link fail state and illuminate
D13. While in the link fail state, all data transmission, reception,
loopback and collision detection fun ctions are disabled and will
remain so until valid data or more the 5 consecutive link beat
pulses appear at the RXD+/- pair.
❏ D22, when blinking, indicates that the Touchscreen Controller, U30
is functional and ready to receive input from the touc hscreen.
❏ D9, when illuminated, indicates the system is accessing the hard

Glossary of Terms
Analog
A term used to describe any device that represents values by a
continuously varied physical property suc h as voltage or current.
API
Abbreviation for Application Programming Inter face (API). The PCWS
API is a hardware API that resides between the application and the
hardware, providing a set of hardware services that the programmer
can call upon to access the POS features of the PCWS.
For example, to open a cash drawer, the programmer calls an API
function. The API determines which system board is installed and
selects the appropriate register and bit in the Configuration and
Control register to open the dr awer. Changes to a register port addres s,
or a new version of the system board is handled by the API and thus
are transparent to the programmer. The current PCWS API supports
all PCWS system boards.
1st Page Contents
PCWS APIs are unique to the operating system where they will be
used. In the Windows 3.1 and Windows 95/NT environments, the API
is implemented as a virtual device driver. In a DOS environment, a
terminate and stay resident program is used.
AUTOEXEC.BAT

BIOS
Abbreviation for Basic Input Output System (BIOS). A layer of
firmware in the PC that resides between the hardware and the
operating system and application programs . The BIOS is store d in nonvolatile EPROM or Flash EEPROM so that it is always available to
start the computer.
The BIOS provides the following services:
❏ The POST (Power On Self Test). The POST initializes and tests
Glossary of Terms
the CPU, RAM, AT chipset, detects and tests any optional hardw are
installed, and assigns resources to Plug and Play devices if
installed. A copy of the current hardwar e configuration is compar ed
with that stored in CMOS RAM. If the current hardware
configuration differs from that stored in CMOS, the BIOS produces
an error message. In either case, the POST then turns control over
to a bootstrap loader to start the operating system from a floppy,
hard disk, or network boot ROM.
Bit
Boot[strap]
❏ The Setup Utility. Consisting of a series of menus, the Setup
Utility provides a central location where the majority of PCWS
Ultra IO Port s are enabled and resources applied. It allows the user
to define such basic items as the type of floppy and hard disk
installed, and the current time and date.
❏ Runtime support. After the PC has booted and is running an
operating system and application software, the BIOS remains
active to handle requests by these programs to use hardware
devices. The BIOS receives these instructions from the operating
system as a software interrupt and translates them into a form the
hardware unde rstands.
A bit is the smallest unit of information the computer can process. The
binary value can either be a 0 or a 1.
Often referred to as the act of booting or re-booting the PC, this term
describes the process of bringing the machine into the desired state by
means of its own actions. Boot[strap] generally refers to the BIOS
software routine whose first few instructions are dedicated to finding
and loading the operating system from a floppy diske tte, a hard disk, or
a network boot ROM.
PCWS Ultra Setup Guide G-3
Glossary of Terms
Boot ROM
An EPROM, that when installed on the System Board, allows the
PCWS to load its operating system, start-up files, and network files,
directly from image files located on a network sever running either
SCO-UNIX, or Windows NT. This allows the workstation to function in
a Client/Server environment such as 3700 RES without a hard disk.
On the Ultra System Board, the Boot ROM is not implemented as a
separate device. It is included in the System Flash BIOS chip an d
enabled as needed through a Boot Menu. See Chapter 2 for more
information.
Buffer

processed, printed, or displayed.
1st Page Contents
Burst Cycles
Refers to the ability of the Pentium® Processor to access up to 16
sequential memory locations during read or write cycles. Burst cycles
are the fastest means of transferring data between the memory and
processor when the data or instructions are located at contiguous
memory addresses.
See Cache and Pipelining.
Bus
A set of electrical conductors used for communication between two or
more devices, a bus is a shared hiway that connects the CPU with
memory and peripheral devices.
Bus Mastering
A device that takes control of the ISA or PCI Bus in order to mediate
its own data transfers. The device that receives data from the bus
master is designated the bus slave or target. A process called bus
arbitration determines which device takes control of the bus.
Byte
A unit of data made up of eight contiguous bits. A byte is the smallest
unit of memory that can be addressed.

Cache
A method of speeding access to information in a slower device by
temporarily storing the information in a faster devic e. Consisting of a
small block of high speed static RAM placed be tween the processor and
main memory, the cache hold copies of the most recently requested code
and data. A dedicated SRAM, the Tag RAM, contains the addresses of
main memory that are stored in the cache.
The processor can access code and data s tored in the c ache m uch fa ster
than when it is stored in main memory. A caching algorithm, built into
the chip set cache controller, determines what data is stored in the
cache. Memory caches differ in size, location, logical arrangement, and
operation.
Glossary of Terms
CD-ROM
An internal cache (also referred to as on-chip, primary, or L1) refers to
the 16 kbytes of cache located inside the Pentium
An external cache (also referred to as secondary, or L2) resides outside
of the processor between it and system DRAM controller.
A write-through cache forces the processor to bypass the cache and
write directly to main memory during memory write cycles.
In a write-back cache, the processor writes data to the faster cache
instead of main memory.
The Ultra System Board is equipped with 512 KB of external write
back pipeline burst cache. Pipeline burst cache refers to a special type
of cache chip designed to take advantage of both the burst cycle
capability and the pipelined arc hitecture of the Pentium processor.
See Burst Cycles and Pipelining.

Centronics Parallel Interface
An industry standard PC IO port, the Centronics Parallel Interface
provides eight parallel data lines plus additional control signals. The
original parallel port was designed as a printer output, thus the data
flow is from PC-to-Printer. A few signals were returned from the
printer to the PC to monitor printer status.
Over time, this port has evolved from a relatively slow unidirectional
port to a much faster bidirectional port capable of bus mastering. The
Ultra System Board supports all enhanced version s of the par allel port.

Glossary of Terms
DMA
Abbreviation for Direct Memory Access. Refers to a technique of
moving information from one place to another without the inter vention
of the CPU. A device called a DMA Controller assumes control of the
system address, data, and co ntrol busses to manage the data transfer.
The AT Bus architecture supports 7 DMA channels, one of which is
used for the floppy disk interface. The remainder are made available to
ISA and PCI bus cards. The IDE interface uses PCI bus mastering to
transfer data to and from the hard disk, without requiring a DMA
channel.
See Bus Mastering.
DRAM
Abbreviation for Dynamic Read Only Memory. The most common form
of memory in a PC. A reasonably fast inexpensive Random Access
Memory, a DRAM stores each bit of information in a capacitor. To
maintain the charge in the capacitor, it must be refreshed. DRAM is a
volatile type of memory, meaning that when power is lost, the contents
of the device is also lost.

EDO RAM
EEPROM
See SRAM.
See Device Driver.
Abbreviation for Extended Data Out. A newer type of FPM memory
designed for Pentium systems that speeds up memory access by
allowing pipelined memory reads. It does this by holding data on its
output from the previous read cycle as its addr ess input changes for the
next read cycle, allowing data to be read as the address for the next
read cycle settles down. EDO RAM speed s up the memory cycle, with
improvements in memory performance of as much as 40% over other
types of memory such as Fast Page Mode (FPM) RAM. EDO RAM is
effective only up to bus speeds of 66MHz.

of the Integrated Drive Electronics that supports more devices at
higher transfer rates. EIDE supports multiple channels, each able to
connect to two devices at transfer rates up to 11 MB/s and hard disks
with capacities greater than 528 Mbytes . It supports at A T Attachment
Pac ket Inteface, which also allows access to CD-ROMs , tape drives, and
optical disks.
EPROM
Abbreviation for Erasable Read Only Memory. EPROMs are basically
used for storing information that is not likely to change, at least not
very often. Unlike DRAM or SRAM, when the power is turned off, an
EPROM retains its contents. However, once programmed, the device
can only be erased and reused by removing it from the circuit and
placing it under a strong ultra-violet light source. Programming is
accomplished by placing the device in an EPROM programmer.
Glossary of Terms
An EPROM is typically used to hold the BIOS in most personal
computers. The BIOS must be stored in non-volatile me mor y since the
computer may be turned off for long period s of time but must be
available to start up the computer and load the ope rating system.
