Chapter 2 Hardware Setup

Chapter 2 Hardware Setup

To Get things ready for Hardware setup !!!

1. We recommend to install your CPU before any other componentes. For
detailed installalation instructions of processor, you can also refer to the
pamphlet enclosed in your CPU package.

2. Installing a cooling fan with a good heatsink is a must for proper heat
dissipation for your CPU. Get ready an appropriate fan with heatsink for
proper installation. Inproper fan and installation will damage your CPU.

3. In case CPU Vcore, CPU clock or Frequency Ratio is adjustable onboard,
please follow the instructions described in the User manual for proper
setup. Incorrect setting will cause damage to your CPU.

The following topics are included in this chapter:

2-1 Pentium 4 CPU Installation

2-3.2 To Remove a DIMM:

• Press down the holding latches on both sides of socket and the module
will be released from the DIMM socket.

2-3 Memory Installation

2-3.1 To Install DIMM Module

• This series of mainboards only supports up to 2GB unbuffered DDR
SDRAM, with 2 DDR DIMM sockets on board.

Do not insert other type of

modules into these sockets.

• DDR DIMM socket has 184-pins and one notch. Insert a DDR SDRAM
vertically into the 184-pin socket with the notch matching the one in the
socket. Press the Module down in a gradual way until it surely reaches
the bottom and clicks straight up the two latches on the left and right of
the socket.

How to tackle with the memory Modules:

• Make sure to unplug your power supply before adding or removing memory
module. Failure to do so may cause severe damage to both your mainboard
and the memory module.

• Pay attention to the orientation of the DIMM slots. Forcing a DIMM in a
socket improperly will damage the memory module and socket.

• Make sure you have the right type of memory module for your mainboard.

Key Point: Press the module down gradually until it has totally
reached the socket bottom and clicked up both two socket latches
completely. If any one of the latches has not turned up completely,
you should unplug the module and press it down the socket a bit
more firmly.

Chapter 2 Hardware Setup

How to tackle with Jumpers:

• Do not remove the jumper when power is on. Always make sure the power
is off before changing any jumper settings. Otherwise, mainboard
could be damaged.

• In the Jumper setting diagram, all jumper pins covered with black marks
stand for closed pins by jumper caps.

2-6.1 Switch 1 CPU Clock Select

• This Series of mainboards are shipped to users with a 5-DIP Switch 1,
by which user can select a CPU clock to match with the Pentium 4
processor selected on board. So users are not recommeded to take
Switch 1 as a tool for overclocking. It is saver and more advisible for
users to select the CPU clock as close as possible to the one marked on
the selected CPU.

• Advice from our Engineering Team:
If you insert a Pentium 4 processor of 100MHz to the CPU socket and

select 103MHz or any higher Switch setting, you are taking the risk of
breaking the stability of your CPU as well as the mainboard. Overclocking
should always take all other components on board into account.

2-6.3 Memory Module Voltage Select (By JP3/JP4)

This function allows you to select the voltage supplied to the DRAM. The
default voltage (2.5V) should be used unless processor overclocking
requires a higher voltage.

NOTE! Using a higher voltage may help when overclocking but may result

in shortening of your computer components’s life. It is strongly recommended
that you leave this setting at its default.

These fan connectors support CPU/System/chassis cooling fan with +12V.
When connecting wire to FAN connectors, users should pay attention
that the red wire is for the positive current and should be connected to
pin +12V, and the black wire is Ground and should be connected to pin
GND. If your mainboard has Hardware Monitor chipset on-board, you
must use a specially designed fan with speed sensor to take advantage
of this function.
For fans with speed sensors, each rotation of the fan blades will send out
2 electric pulses, by which System Hardware Monitor will work out the
fan rotation speed by counting the pulses.

NOTE : We use 3 “Yellow” fan connectors to mark that they support fan

speed sensor function.

2-7.4 Thermal Sensor Connector RT2 (Optional)

1. Connector RT1: A blue thermal resistor is already soldered to connector
RT1 so as to sense the temperature round the mainboad. What RT1
does is to transmit the thermal signal to BIOS or Hardware Monitor.

2. Connector RT2: A thermal cable is needed to connect RT2 to on-board
devices such as HDD, Graphics card etc., so as to detect the temperature
generated therein. Please connect the end (a) of the thermal cable to
mainboard RT2 header, and tape another end (b) of thermal cable on to
the device which you want to monitor. After you have finished the thermal
cable installation, you will see the detected temperature in BIOS setup

or Hardware monitor utility.

2-8 IRQ Description

• Both ISA and PCI expansion cards may require IRQs. System IRQs are
available to cards installed in the ISA expansion bus first, then any
remaining IRQs are available to PCI cards. Currently, there are two types
of ISA cards.

• The original ISA expansion card design, now referred to as “Legacy” ISA
card, requires you to configure the card’s jumpers manually and then
install it in any available slot on the ISA bus. To see a map of your used
and free IRQs in Windows 98, the Control Panel in My Computer, contains a
System icon, which gives you a Device Manager tab. Double-Clicking on
a specific hardware device gives you a Resources tab which shows the
Interrupt number and address. Double-Clicking Computers to see all the
interrupts and addresses for your system. Make sure that each ISA device
should be assigned to one IRQ respectively. If ISA device share IRQ with
any other device, your computer will easily get into trouble.

Chapter 4 BIOS Setup

The following topics are included in this chapter:

4-1 About BIOS Setup
4-2 To run BIOS Setup
4-3 About CMOS
4-4 The POST (Power On Self Test)
4-5 To upgrade BIOS
4-6 BIOS Setup

THE BIOS

• BIOS stands for Basic Input and Output System. It was once called ROM
BIOS when it was stored in a Read-Only Memory(ROM) chip Now
manufacturers would like to store BIOS in EEPROM which means
Electrically Erasable Programmable Memory. BIOS used in this series of
mainboard is stored in EEPROM, and is the first program to run when you
turn on your computer.

• BIOS performs the following functions:

1. Initializing and testing hardware in your computer (a process called
“POST”, for Power On Self Test).

2. Loading and running your operating system.

3. Helping your operating system and application programs manage your
PC hardware by means of a set of routines called BIOS Run-Time Service.

Chapter 4 BIOS Setup

51

4-1 About BIOS Setup

• BIOS setup is an interactive BIOS program that you need to run when:

1. Changing the hardware of your system. (For example: installing a new
Hard Disk etc.)

2. Modifying the behavior of your computer. (For example: changing the
system time or date, or turning special features on or off etc.)

3. Enhancing your computer’s behavior. (For example: speeding up
performance by turning on shadowing or cache.)

4-2 To run BIOS Setup

• First access BIOS setup menu by pressing < DEL > key after “POST” is
complete ( before OS is loaded ). BIOS will then display the following
message:

Press “DEL” to enter “SETUP”

4-3 About CMOS

• CMOS is the memory maintained by a battery. CMOS is used to store the
BIOS settings you have selected in BIOS Setup. CMOS also maintains the
internal clock. Every time you turn on your computer, the BIOS Looks into
CMOS for the settings you have selected and configures your computer
accordingly. If the battery runs out of power, the CMOS data will be lost and
POST will issue a “CMOS invalid” or “CMOS checksum invalid” message.
If this happens, you have to replace the battery and do some proper
settings in BIOS Setup.

4-4 The POST ( Power On Self Test )

• POST is an acronym for Power On Self Test. This program will test all
things the BIOS does before the operating system is started. Each of
POST routines is assigned a POST code, a unique number which is sent
to I/O port 080h before the routine is executed.

85DR-C

52

4-5 To upgrade BIOS

• System BIOS is incorporated into a Flash memory component. Flash BIOS
allows user to upgrade BIOS without the need to replace an EPROM
component.

• The Upgrade Utility can be loaded on a floppy diskette to execute saving,
verifying, and updating the system BIOS. The Upgrade Utility can also be
run from a hard disk drive or a network drive.

4-5.1 Before Upgrading BIOS

• It is highly recommended that you save a copy of the original mainboard
BIOS along with a Flash EPROM Programming utility (AWDFLASH.EXE)
to a bootable floppy disk so that you can reinstall the BIOS when needed.

4-5.2 Upgrade Process

• Normally, to upgrade BIOS is unnecessary if the system is working
fine Users should only upgrade the BIOS when you experience incompatible
problems or need to create new features.

• “AWDFLASH.EXE” is a Flash EPROM Programming utility that up dates
the BIOS by uploading a new BIOS file to the programmable flash ROM
on the mainboard. This program only works in DOS environment, the
utility can not be executed in win95/98, ME, NT or WINDOWS 2000

environment.

• Please follow the steps below for upgrading the system BIOS:

Step 1. Please visit the board maker’s website, download latest BIOS file and
award flash utility “AWDFLASH.EXE”. The BIOS file format will be *.
bin, of which “ * ” stands for the specific BIOS file name.

Step 2. Create a bootable diskette. Then copy the BIOS file and award
flash utility “AWDFLASH.EXE” into the diskette.

Step 3. Insert the diskette into drive A, reboot your system and boot from the
diskette.

Chapter 4 BIOS Setup

53

Step 4. Type awdflash *.bin /sn/py/cc and then press <Enter> to run BIOS
upgrade program. (*.bin depends on your mainboard model and
version code. Instead of typing “*”, you should type specific file name
for your specific mainboard).

Step 5. Please press <F1> or <F10> to exit or reset your system.

Step 6. You will need a message “CMOS checksum error-Default loaded”
during booting the system. Press <Del> to run CMOS setup utility,
then reload “LOAD SETUP DEFAULTS” or “Load Optimized
Defaults” and save this change.

The parameters of AWDFLASH.EXE

/sn: No original BIOS backup
/py: Program flash memory
/cc: Clear CMOS data (and update data automatically) after pro­ gramming

Users can type AWDFLASH /? to get further details about the parameters.
Incorrect usage of the parameter will damage the BIOS information, so we
strongly recommend user to leave parameters alone unless you fully understand
their function.

Warning ! If the message “ Write Fail ” appears while Award “FLASH

MEMORY WRITER” is verifying Flash memory, just repeat the process.
Please DO NOT reset or turn off the system. If the award memory flash
utility is not able to update the BIOS successfully, your system may not be
able to boot up.

2. Use one of the arrow keys to move between options and modify the selected
options by using PgUp / PgDn / + / - keys. An explanation of the <F> keys
follows:

<F1>: “Help” gives options available for each item.
<F5>: Get the previous values. These values are the values with which the
user starts the current session.
<F6>: Load all options with the BIOS default values.
<F7>: Load all options with the Setup default values.

3. Press <ESC> to return to the Main Menu when you finish setting up all
items. Now please read the following information for the “Advance BIOS
Features “ setup:

CPU L1 & L2 Cache Cache memory is additional memory that is much

faster than conventional DRAM (system memory).
CPUs from 486-type up contain internal cache
memory (L1), and most, but not all, modern PCs
have external cache memory (L2). When the CPU
requests data, the system transfers the requested
data from the main DRAM into cache memory, for
faster access by the CPU.

Virus Warning When enabled, you receive a warning message if a

program (specifically, a virus) attempts to write to the
boot sector or the partition table of the hard disk drive.
You should then run an antivirus program. Keep in
mind that this feature protects only the boot sector,
not the entire hard drive.

NOTE: Many disk diagnostic programs that access the boot sector table

can trigger the virus warning message. If you plan to run such a
program, we recommend that you disable the virus warning.

Swap Floppy Drive When enabled, floppy drives A and B will be exchanging

without any physical connection and modification on the
cables.

First/Second/Third/

Other Boot Device

The BIOS attempts to load the operating system from
the devices according to your selected priority.
The choices: Floppy; LS120; HDD-0;SCSI;
CDROM;HDD-1;HDD-2;HDD-3;
ZIP100;LAN;RAID;Disabled.

Boot Up Floppy Seek When enabled, the BIOS tests (seeks) floppy drives

to determine whether they have 40 or 80 tracks. Only
360-KB floppy drives have 40 tracks; drives with
270KB, 1.2MB, and 1.44MB capacity all have 80
tracks. Because very few modern PCs have 40-track
floppy drives, we recommend that you set this field
to disabled to save time.

Boot Up NumLock

Status

Toggle between On or Off to control the state of
the NumLock key when the system boots. If On,
the numeric keypad is in numeric mode. If off, the
numeric keypad is in cursor control mode.

Gate A20 Option Gate A20 refers to the way the system addresses

memory above 1 MB (extended memory). When
set to Fast, the system chipset controls Gate A20.
When set to Normal, a pin in the keyboard controller
controls Gate A20. Setting Gate A20 to Fast improves
system speed, particularly with OS/2 and Windows.

Boot Other Device When enabled, this item allows you to select other boot

device. The choices: Enabled; Disabled

Quick Power On Self

Test

Select Enabled to reduce the amount of time required to
run the power-on self-test (POST). A quick POST skips
certain steps. We recommend that you normally enable
quick POST.

DRAM RAS# to CAS#

Delay

This field lets you insert a timing delay between the
CAS and RAS strobe signals, used when DRAM is
written to, read from, or refreshed. Fast gives faster
performance and Slow gives more stable
performance. This field applies only when synchronous
DRAM is installed in the system.
The Choices: 2; 3

CAS Latency Time When synchronous DRAM is installed, the number

of clock cycles of CAS latency depends on the
DRAM timing. Do not reset this field from the de­fault value specified by the system designer.

DRAM RAS#

Precharge

If an insufficient number of cycles is allowed for the
RAS to accumulate its charge before DRAM refresh,
the refresh may be incomplete and the DRAM may
fail to retain data. Fast gives faster performance;
and Slow gives more stable performance. This field
applies only when synchronous DRAM is installed
in the system.
The Choices: 2; 3

3. Press <ESC> to return to the Main Menu when you finish setting up all
items. Now please read the following information for the “Advanced Chipset
Features” setup:

Active to Precharge

Delay

This field allows you to select a CAS Precharge delay

DRAM Timing Select-

able

The value in this field depends on performance
parameters of the installed memory chips
(DRAM). Do not change the value from the factory
setting unless you install new memory that has a
different performance rating than the original
DRAMs.

AGP Aperture Size Choices: 32; 64 MB. Memory mapped and graphics

data structures can reside in a Graphics Aperture.
This area is like a linear buffer. BIOS will automatically
report the starting address of this buffer to the O.S.

Delay Prior to Thermal The chipset has an embedded 32-bit posted write

buffer to support delay transactions cycles.
This item allows you to choose a delay timing
before a new Thermal reading is taken.

Memory Hole At 15M-

16M

You can reserve this area of system memory for ISA
adapter ROM. When this area is reserved, it cannot
be cached.

Video BIOS Cacheable

Selecting Enabled allows caching of the system
BIOS ROM at C0000h to C7FFFh, resulting in video
performance. However, if any program writes to this
memory area, a system error may result.

System BIOS

Cacheable

Selecting Enabled allows caching of the system
BIOS ROM at F0000h to FFFFFh, resulting in
better system performance.
Default: Disabled

4-6.11 Set Supervisor / User Password

• These two options allow you to set your system passwords. Normally, the
supervisor has a higher priority to change the CMOS setup option than the
users. The way to set up the passwords for both Supervisor and Users are
as follows:

1. Choose “Change Password” in the Main Menu and press <Enter>. Then
following message appears:

“Enter Password : “

2. The first time you run this option, enter your password up to 8 characters
and press <Enter>. (The screen does not display the entered characters.)

3. After you enter the password, the following message appears prompting
you to confirm the password:

“Confirm Password : “

4. Enter the same password “exactly” the same as you have just typed to
confirm the password and press <Enter>.

5. Move the cursor to Save & Exit Setup to save the password.

6. If you need to delete the password entered before, choose the Supervisor
Password and press <Enter>. It will delete the password that you have
entered before.

7. Move the cursor to Save & Exit Setup to save the option you have just
configured; otherwise the old password will still be there the next time you
turn your system on.

8. Press <Enter> to exit to the Main Menu.

NOTE: If you forget or lose the password, the only way to access the

system is to clear the CMOS RAM. All setup informations will be lost and
you need to run the BIOS setup program again.

Appendix-3 Technical Terms

AC’97

AC’97 is a device designed to include a digital processor for modem and an
audio CODEC for analog I/O. These two parts are linked together by AC’97
link bus. Putting the digital processor into the main system chipset will reduce
the cost of sound/modem onboard solution.

ACPI (Advanced Configuration & Power Interface)

ACPI is developed together by Intel, Microsoft and Toshiba. This interface
provides a channel of management of the PC system and its hardware such
as CPU and BIOS, pushing the PC power management to
a more advanced and user-friendly level.

AGP (Accelerated Graphic Port)

AGP is a bus interface targeted for high-performance 3D graphics. AGP
takes advantage of both rising and falling edge of the 66MHz clock. For 2X
AGP, the data transfer rate is 66MHz x 4byte x 2 = 528MB/s. AGP
4X mode is 66MHz x 4byte x 4 = 1056MB/s.

AMR (Audio/Modem Riser)

AMR is an interface to connect the CODEC circuit of AC’97 sound/modem
solution to the mainboard through an AMR card and an AMR connector.

APM (Advanced Power Management)

APM is developed by Intel and Microsoft , intending for PC power
management through the system BIOS. Through APM, the PC power
consumption can be reduced to 5W or lower.

ATA (AT Attachment), ATA/66, ATA/100

ATA is the specification of disk drive interface, that integrates the controller
on the disk drive itself with the IDE technology.
ATA/66 uses both rising edge and falling edge to provide a data
transfer rate 16.6MB/s x4 = 66MB/s. To use ATA/66, you need
special ATA/66 IDE cable.
ATA/100 also uses both rising edge and falling edge as ATA/66,
but clock cycle time is reduced to 40ns. The data transfer rate is
(1/40ns) x 2 bytes x 2 = 100MB/s. To use ATA/100, you need
special 80-wire IDE cable, the same as ATA/66.

85DR-C

94

ATAPI (AT Attachment Packet Interface)

This is the exension of the EIDE (extended IDE) that enables the interface
to support CD-ROM players and tape drives.

BIOS (Basic Input/Output System)

BIOS is a set of assembly routine/program that resides in EPROM or Flash
ROM. BIOS controls Input/output devices and other hardware devices of
the mainboard. Generally, operation system and drivers will access BIOS
before accessing hardware devices so as to enhance the portability of the
hardware devices.

Bus Master IDE (DMA mode)

An IDE interface is an interface for mass storage devices, in which the
controller is integrated into the disk or CD-ROM itself. To reduce the
workload of the CPU, the bus master IDE device transfers data from/to
memory without interrupting CPU, and releases CPU to operate concurrently
while data is transferring between memory and IDE device. You need the
bus master IDE driver and the bus master IDE HDD to support bus master
IDE mode.

CAS (Column Address Strobe)

CAS is a technology of DRAM writes and reads. The number of clock cycles
of the CAS signals is depending on the DRAM timing.

CNR (Communication and Networking Riser)

CNR interface provides a cost reducing method of implementing LAN, home
networking, DSL, USB, wireless, audio and modem subsystems through a
CNR card and a CNR connector.

CODEC (Coder and Decoder)

Normally, CODEC means a circuit that can do digital to analog conversion
and vice versa. It is part of AC’97 sound/modem solution.

DDR (Double Data Rated) SDRAM

DDR SDRAM essentially doubles the memory speed of SDRAMs without
increasing the clock frequency.

Chapter 4 BIOS Setup

95

DIMM (Dual In Line Memory Module)

DIMM socket is built with a 168-pin assignment and supports 64-bit data.
DIMM can be single or double sided. The golden finger signals on each
side of the module are different, and that is why it is called Dual In Line.
Almost all DIMMs are made with SDRAM now, which operate at 3.3V.
Some old DIMMs are made by FPM/EDO and only operate at 5V.

DMA (Direct Memory Access)

Channel for communications between memory and surrounding devices.

ECC (Error Checking and Correction)

The ECC algorithm has the ability to detect double-bit error and automatically
correct single-bit error while parity mode can only detect single-bit error.

ECP (Enhanced Communication Port)

ECP is a technology designed to improved I/O for parallel ports.

EPP (Enhanced Parallel Port)

EPP is a standard that supports data transfer rates of up to 500 kps for parallel
printers

EDO (Extended Data Output) Memory

Unlike traditional FPM (Fast Page Mode) memory that tri-states the memory
output data to start the pre-charge activity, EDO DRAM holds the memory
data valid until the next memory access cycle, which is similar to pipeline
effect in reducing one clock state.

EEPROM (Electronic Erasable Programmable ROM)

Both EEPROM and Flash ROM can be re-programmed by electronic signals,
but the interface technology is different. Size of EEPROM is much smaller
than flash ROM. BIOS is now generally stored in EEPROM or Flash ROM.

EPROM (Erasable Programmable ROM)

Traditional mainboard stores BIOS codes in EPROM which can only be
erased by ultra-violet (UV) light. If BIOS has to be updated, you need to
remove EPROM from mainboard, clear data by UV light, re-program, and
then insert it back to socket.

85DR-C

FC-PGA (Flip Chip-Pin Grid Array)

FC means Flip Chip, while FC-PGA is a new package of Intel for Pentium
III CPU. It is compatible with SKT370 socket, but requires mainboard to
add some signals on socket 370.

Flash ROM

Flash ROM can be re-programmed by electronic signals. It is easier for
BIOS to upgrade by a flash utility, but it is also easier to be infected by
virus. Because of increase of new functions, BIOS size is increased from
64KB to 256KB (2M bit) or more.

FSB (Front Side Bus)

FSB is the data channel connecting the Processor to chipset, RAM, mainboard
buses, AGP socket etc. Its speed is in terms of MHz and is talked to as FSB
clock:
FSB Clock means CPU external bus clock.
CPU internal clock = CPU FSB Clock x CPU Clock Ratio

IEEE 1394

IEEE 1394 is a low-cost digital transfer interface with transfer rate at 100,
200 or 400 Mbps. It provides solutions of connecting digital television devices
and Serial Bus Management. There are two type of IEEE 1394 data transfer:
asynchronous and isochronous. Isochronous data channels provide
guaranteed data transport at a pre-determined rate. This is especially important
for time-critical multimedia data where just-in-time delivery eliminates the
need for costly buffering.

Parity Bit

The parity bit mode of error detection uses 1 parity bit for each byte. Normally
it is even parity mode, that is, each time the memory data is updated, parity
bit will be adjusted to have even count “1” for each byte. Next time when
memory is read with odd number of “1”, the parity error is occurred and this
is called single bit error detection.

PC-100 DIMM

SDRAM DIMM that supports 100MHz CPU FSB bus clock.

PC-133 DIMM

SDRAM DIMM that supports 133MHz CPU FSB bus clock.

Chapter 4 BIOS Setup

97

PC-1600 or PC-2100 DDR SDRAM

PC-1600 DDR SDRAM with a 64-bit data bus doubles the data transfer rate
of PC100 SDRAM and hence provides data transfer bandwidth up to 100x64/
8x2=1600MB/s. PC2100 DDR SDRAM doubles the data transfer rate of
PC-133 and hence provides data transfer bandwidth up to 133x64/
8x2=2100MB/s.

PCI (Peripheral Component Interface) Bus

A high speed data channel for the internal connection of peripheral devices
and the computer system through a PCI expansion card.

PnP (Plug and Play)

The PnP specification suggests a standard register interface for both BIOS
and operating system (such as Windows 95). These registers are used by
BIOS and operating system to configure system resource and prevent any
conflicts. PnP BIOS or operating system will automatically allocate the IRQ/
DMA/Memory. Currently, almost all the PCI cards and most ISA cards are
already PnP compliant.

POST (Power-On Self Test)

The BIOS self-test procedure after power-on. It is generally the first or the
second program shown on your monitor screen during system boot.

RAS (Row Address Strobe)

RAS is a technology that DRAM writes and reads to the Row addresses,
while a CAS (Column Address Strobe) signal is used to validate the column
address. The signals are generally sent CAS before RAS.
(in Network field, RAS stands for Remote Access Services).

RDRAM (Rambus DRAM)

Rambus DRAM is a memory technology that uses large burst mode data
transfer of up to 1.6GHz. It is import to know that RDRAM technology
helps set up a system level improvement, not just a component upgrade.

RIMM (Rambus Inline Memory Module)

RIMM is built with a 184-pin architecture module that supports RDRAM
memory technology. A RIMM memory module may contain up to maximum
of 16 RDRAM devices.

85DR-C

98

SDRAM (Synchronous DRAM)

SDRAM is one of the Dynamic Random Access Memory (DRAM)
technologies that allow DRAM to use the same clock as the CPU host clock
(EDO and FPM are asynchronous and do not have clock signal). SDRAM
comes in 64-bit 168-pin DIMM and operates at 3.3V.

SIMM (Single In Line Memory Module)

SIMM socket is only 72-pin, and is only single side. The golden finger
signals on each side of PCB are identical. That is why it is called Single In
Line. SIMM is made of FPM or EDO DRAM and supports 32-bit data.
SIMM is phased out in current mainboard design.

SPD (Serial Presence Detect)

SPD is a small ROM or EEPROM device resided on the DIMM or RIMM.
Memory module information such as DRAM timing and chip parameters
can be stored into SPD so that BIOS can access it and use it to decide best
timing for this DIMM or RIMM.

UART (Universal Asynchronous Receiver/transmitter)

UART is built in a chip that controls the data sent to and received from a
serial port. A 16550 UART is now standard in most PCs, and supports modem
speed up to 57,600 bps and beyond and direct connect speed of 115,200
bps. Many UARTs have built-in errors in the internal code and just do not
work correctly with many external modems. UART is also found as the
serial interface on internal modem.

Ultra DMA

Ultra DMA (or, more accurately, Ultra DMA/33) is a protocol for transferring
data at 33.3MB/s between a hard disk drive through the computer’s data
path (or bus) to the computer’s random access memory (RAM). The transfer
data is twice as fast as the previous Direct Access Memory (DMA) interface.
The latest Ultra DMA has advanced to Ultra DMA/66 and Ultra DMA/100.

16.6MB/s x2 = 33MB/s

16.6MB/s x4 = 66MB/s

16.6MB/s x6 = 100MB/s

99

USB (Universal Serial Bus)

USB is a 4-pin serial peripheral bus that is capable of cascading low/medium
speed peripherals (less than 10Mbit/s) such as keyboard, mouse, joystick,
scanner, printer and modem.

VCM (Virtual Channel Memory)

NEC’s Virtual Channel Memory (VCM) is a new DRAM core architecture
that dramatically improves the memory system’s ability to service multimedia
requirements. VCM increases memory bus efficiency and performance of
any DRAM technology by providing a set of fast static registers between
the memory core and I/O pins. Using VCM technology results in reduced
data access latency and reduced power consumption.

VRM (Voltage regulator Module)

This is a small module installed on a mainboard to regulate the voltage fed
to the processor on board. Voltage regulator can be built on board in various
way. VRM is a socketed type of regulator module which is easier to change
when needed.

Zero Wait State

When memory is operating at its fastest speed in its course of fetching and
yielding data, it allows no “no-op” cycle and is called in a zero wait state.
On the other hand, a memory is in a wait state , after it gets a command to
fetch data, it waits for one , two or more cycles to assure that the expected
data is in the buffer.

ZIP file

Zip file is a compressed file with a reduced file size.

Zoom

To zoom is to make a window or screen larger or smaller in a Graphical
User Interface of a computer system. Usually, to “zoom in” means to enlarge,
and to “zoom out” means to reduce size.
