Chapter 2  
Hardware Installation  
This chapter summarizes the steps to install the 586IVX system board  
into your system unit. It also includes a description of the area in which  
you must work and directions for memory installation. Before installing  
the system board, obtain the memory you plan to install. Refer to the  
System Memory section for the number and type of memory modules  
needed for the amount of memory you require.  
Preparing the Area  
Before unpacking the system board, make sure the location you have  
selected is relatively free of dust and static electricity. Excessive expo-  
sure to dust, static electricity, direct sunlight, excessive humidity, ex-  
treme cold, and water can damage the operational capabilities of your  
system board. Avoid placing the unit on surfaces such as carpeted  
floors. These areas also attract static electricity which can damage  
some circuits on your system board.  
Make sure the power source has a properly grounded, three-pronged  
socket. It is essential that the power connection be properly grounded  
for correct functioning of your system board. For further protection, we  
recommend that you use a surge suppressor. This will protect the sys-  
tem board from damage that may result from a power surge on the  
electrical line.  
Move items that generate magnetic fields away from your system board  
since magnetic fields can also damage your system board. Once you  
have selected the ideal location, unpack the 586IVX system board care-  
fully.  
Handling the System Board  
It is quite easy to inadvertently damage your system board even before  
installing it in your system unit. Static electrical discharge can damage  
computer components without causing any signs of physical damage.  
You must take extra care in handling the system board to ensure  
against electrostatic build-up.  
9
Static Electricity Precautions  
1. To prevent electrostatic build-up, leave the board in its anti-static  
bag until you are ready to install it.  
2. Wear an antistatic wrist strap.  
3. Do all preparation work on a static-free surface with the system  
board components facing up.  
4. Hold the system board by its edges only. Be careful not to touch  
any of the components, contacts or connections, especially gold  
contacts, on the board.  
5. Avoid touching the pins or contacts on all modules and connectors.  
Hold modules and connectors by their ends.  
Warning:  
Electrostatic discharge (ESD) can damage your processor, disk drives,  
add-in boards, and other components. Perform the upgrade instruction  
procedures described at an ESD workstation only. If such a station is  
not available, you can provide some ESD protection by wearing an anti-  
static wrist strap and attaching it to a metal part of the system chassis.  
If a wrist strap is unavailable, establish and maintain contact with the  
system chassis throughout any procedures requiring ESD protection.  
Installing the System Board  
If you are installing the 586IVX system board, the following outlines the  
basic installation steps. Before installing the system board into your sys-  
tem unit, you should prepare the tools you will need.  
You will need:  
One medium size, flat-bladed screwdriver  
One medium Phillips screwdriver  
One needle-nosed pliers  
One small nutdriver  
1. Unlock your system unit. Turn off the power and disconnect all  
power cords and cables.  
10  
2. Remove the system unit cover. Refer to the manufacturer’s instruc-  
tions if necessary.  
3. Detach all connectors from the old system board and remove ex-  
pansion cards seated in any expansion slots.  
4. Loosen the screws holding the original system board and remove  
the board from the system. Save the screws.  
5. Remove the 586IVX from its original packing box. Be careful to  
avoid touching all connectors and pins on the board. Please refer to  
the handling instructions on pages 9-10 for proper handling tech-  
niques.  
6. Insert the memory modules into the memory banks on the 586IVX. The  
quantity and location of the memory modules depends on the  
memory configuration and type of modules you intend to use.  
7. Insert the cache module, if any, into the cache module slot on the  
586IVX. Refer to the Cache Memory section for upgrading your  
cache memory.  
8. Install the CPU. Be sure pin 1 of the CPU is aligned with pin 1 of  
the socket.  
9. Set the corresponding jumpers.  
10. Install the prepared 586IVX system board into the case and replace  
the screws.  
11. Reinstall all cards and connectors and replace the system unit  
cover. Reconnect all power cords and cables.  
If you are using an ATX power supply, install the 20-pin ATX power  
cable connector into location PL1 on the system board. The 20-pin  
connector can be inserted into PL1 only if pin 1 of the connector is  
aligned with pin 1 of PL1.

System Memory  
The 586IVX system board supports One kinds of memory modules:  
SIMM. , which uses DRAM. Refer to page 12 for the locations of the nd  
SIM sockets.  
SIMM  
The SIMM (Single In-line Memory Module) sockets are divided into two  
banks on the system board, Bank 0 and Bank 1. Each bank consists of  
2 SIMM sockets.  
You will need either 2 or 4 pieces of SIM modules, depending on the  
amount of memory you intend to install. The system board will not work  
if you install 1 or 3 pieces. Make sure you insert the same type of  
SIMMs in one bank. You can install SIMMs in either of the banks, Bank  
0 or Bank 1, but you must populate one bank first before going to the  
next bank.  
The 586IVX system board can support 8MB to 128MB of memory using  
1MBx32, 2MBx32, 4MBx32, or 8MBx32 72-pin SIMMs. The table on the  
next page shows the supported SIM modules and their corresponding  
memory sizes.

Installing a SIM Module  
A SIM module simply snaps into a socket on the system board. Pin 1 of  
the SIM module must correspond with Pin 1 of the socket.  
notch  
key  
1. Position the SIMM above the socket with the “notch” in the module  
aligned with the “key” on the socket.  
2. Seat the module at a 45° angle into the bank. Make sure it is com-  
pletely seated. Tilt the module upright until it locks in place in the  
socket.  
Cache Memory  
The 586IVX system board can support 256KB pipeline burst, direct map  
write-back cache SRAM. Your system board may come with 256KB  
cache mounted at locations U11 and U17 of the system board.  
16  
CPU Installation  
The 586IVX allows for easy installation of CPUs. Make sure all jumpers are  
set correctly before applying power or you may damage the CPU or system  
board. Use a needle-nosed plier to move the jumpers if necessary.  
Jumpers JP10, JP11 and JP12 are used to set the external bus clock of  
your processor. Refer to the following pages for the external bus clock that  
corresponds to your processor and set these jumpers accordingly. The  
clock generator will determine the external bus clock that must be sent to  
the processor through these settings.  
Jumper JP5 is used to set the frequency ratio of your processor. Refer to  
the following pages for the frequency ratio that corresponds to your proces-  
sor and set this jumper accordingly.  
After setting these jumpers, an Intel processor will multiply the external bus  
clock by the frequency ratio to become the internal clock speed. Internal  
clock speed is the commonly used speed of Intel processors in the market  
and is the actual operating clock of the processor (external bus clock x  
frequency ratio = internal clock speed).  
Cyrix and AMD processors use the P-rating system which is the overall  
CPU performance rating. Under the system, these processors slightly out-  
perform Intel’s Pentium processors.  
Jumpers JP2, JP3, JP4 and JP7 are used to set the voltage of your proces-  
sor. Make sure these jumpers are set correctly, otherwise your system will  
hang.

Installing Upgrade CPUs  
The 586IVX is equipped with a 321-pin Zero Insertion Force (ZIF)  
socket at location U29 of the system board. Refer to page 12 for the  
location of the ZIF socket. This socket is designed for easy removal of  
an old CPU and easy insertion of an upgrade CPU. The ZIF socket  
allows you to carefully place the new CPU into its position. If you need  
to apply excessive force to insert the CPU, you are not installing the  
CPU correctly.  
Warning:  
Open the socket only if you are actually installing a CPU. The warranty  
on the original CPU will be voided if the S/N seal is broken. Before  
proceeding with the upgrade, take note of the following. The micropro-  
cessor and heatsink may be hot if the system has been running. To  
avoid the possibility of a burn, power the system off and let the proces-  
sor and heatsink cool for 20 minutes.  
The 321-pin ZIF socket consists of five rows of pin holes on each side.  
To prevent improper CPU installation, the ZIF socket has a Plug/Keying  
mechanism. Several holes in the socket are plugged so that the CPU  
will go in only one way. If you cannot easily insert the CPU, verify that  
pin 1 of the CPU is aligned with pin 1 of the socket.  
Zero Insertion Force (ZIF) Socket  
To install an upgrade CPU, do the following:  
1. Make sure the handle on the side of the ZIF socket is up. To raise  
the handle, push it down, slightly pull it out to the side, then raise it  
as far as it will go. It may be necessary to initially apply a small  
21  
amount of sideways force to free the handle from its retaining “tab”.  
Once clear of the “tab”, the handle will open relatively easily. The  
top plate will slide back. Do not use screwdrivers or other tools to  
open the socket, or you may damage the system or socket.  
Handle  
Lifting the Handle  
2. Once the lever is completely up, remove the old CPU carefully by  
lifting it straight out of the socket. You are now ready to insert the  
new CPU.  
Pin 1  
3. Position the CPU above the ZIF socket. Make sure pin 1 of the  
CPU is aligned with pin 1 of the socket. Lower the chip until the  
pins are inserted properly in their corresponding holes. Remember  
that very little force is needed to install the CPU. If the CPU is not  
easily inserted, verify whether or not pin 1 of the CPU is aligned  
with pin 1 of the socket. Applying too much pressure can damage  
the CPU or the socket.  
22  
Pin 1  
Positioning the CPU Above the ZIF Socket  
4. Push the handle down until the handle locks into place. The top  
plate will slide forward. You will feel some resistance as pressure  
starts to secure the CPU in the socket. This is normal and will not  
damage the CPU. However, if the handle is not completely closed,  
damage to the CPU and/or system board may result.  
Installing A Fan/Heatsink  
You must choose a fan/heatsink suitable for the processor installed on  
your system board. Position the fan/heatsink on the CPU such that the  
air from the side of the fan/heatsink will flow across the heat regulators  
on the system board. See the figure below.  
Clearance Requirements  
Your CPU comes with a heatsink mounted on top. To maintain proper  
airflow once the upgrade is installed on the system board, the CPU and  
heatsink require certain space clearances. The clearance above the  
CPU’s fan/heatsink must be at least 0.4 inches. The clearance on at  
23  
least 3 of 4 sides of the processor and heatsink must be at least 0.2  
inches. All cables (for floppy drive, hard drive, CD-ROM, etc.) must be  
routed clear of the CPU and its airspace.  
Fan Exhaust  
The CPU must be kept cool by using a fan with heatsink. The tempera-  
ture of the air entering the fan/heatsink cannot exceed 45oC (113oF).  
The ambient or room temperature must be below 37oC (99oF).  
Jumper Settings for CMOS Clear  
Jumper JP1  
CMOS Clear Select  
If, for some reason, the CMOS becomes corrupted, the system can be  
reconfigured with the default values stored in the ROM BIOS. To load  
the default values, power off your system and set JP1 to On. Power on  
your system. After you boot up an operating system, turn your system  
off again. Set JP1 back to its default setting, Off.

Serial Ports  
The 586IVX is equipped with two serial ports at locations CN5 (COM 2)  
and CN6 (COM 1) of the system board. These built-in serial ports are  
RS-232C asynchronous communication ports with 16C550A-compatible  
UARTs that can be used with modems, serial printers, remote display  
terminals, and other serial devices.  
Parallel Port  
The 586IVX system board has a standard printer port (CN7) for interfac-  
ing your PC to a parallel printer. It supports SPP, ECP and EPP modes.  
You can set the port’s mode in the Integrated Peripherals setup of the  
Award BIOS (Refer to Chapter 3).

Floppy Disk Drive Controller  
The 586IVX system board is equipped with a shrouded floppy disk  
header that supports two standard floppy disk drives. You can install  
any 360KB, 720KB, 1.2MB, 1.44MB, or 2.88MB floppy disk drives. To  
prevent improper floppy cable installation, the shrouded floppy disk  
header has a keying mechanism. The 34-pin connector on the floppy  
cable can be placed into the header only if pin 1 of the connector is  
aligned with pin 1 of the header.  
Connecting the Floppy Disk Cable  
1. Install the 34-pin header connector into the shrouded floppy disk  
header (J10) on the system board. The colored edge of the ribbon  
should be aligned with pin 1 of connector J10.  
2. Install the other 34-pin header connector(s) into the disk drive(s).  
Align the colored edge of the daisy chained ribbon cable with pin 1  
of the drive edge connector(s). The end-most connector should be  
attached to the drive you want to designate as Drive A.  
IDE Hard Disk Interface  
The 586IVX system board is equipped with two shrouded PCI IDE  
headers that will interface four Enhanced IDE (Integrated Drive Elec-  
tronics) hard disk drives.  
Note:  
Only Enhanced IDE hard drives or ATAPI CD-ROMs can be connected  
to the IDE interface.  
Connecting the IDE Hard Disk Interface  
To prevent improper IDE cable installation, each shrouded PCI IDE  
header has a keying mechanism. The 40-pin connector on the IDE  
cable can be placed into the header only if pin 1 of the connector is  
aligned with pin 1 of the header.  
27  
Header  
Note:  
An IDE cable with a standard 40-pin connector (without the keying  
mechanism) can be installed in the shrouded PCI IDE header. Be ex-  
tremely careful to match the colored edge of the ribbon with pin 1 of the  
header.  
Connecting the Hard Disk Cable  
1. If you are connecting two hard drives, install the 40-pin connector of  
the IDE cable into the primary shrouded IDE header (connector  
J11). If you are adding a third or fourth IDE device, install the 40-  
pin connector of the other IDE cable into the secondary shrouded  
IDE header (connector J12).  
2. Install the other 40-pin header connector(s) into the device with the  
colored edge of the ribbon cable aligned with pin 1 of the drive  
edge connector(s).  
Note:  
Refer to your disk drive user’s manual for information about selecting  
proper drive switch settings.  
Adding a Second IDE Hard Drive  
When using two IDE drives, one must be set as the master and the  
other as the slave. Follow the instructions provided by the drive manu-  
facturer for setting the jumpers and/or switches on the drives.  
28  
We recommend that you use Enhanced IDE hard drives from the same  
manufacturer. In a few cases, drives from two different manufacturers  
will not function properly when used together. The problem lies in the  
hard drives, not the 586IVX system board.  
Preparing an IDE Drive for Use  
IDE disk drives are already low-level formatted, with any bad-track er-  
rors entered, when shipped by the drive manufacturer. Do not attempt  
to do a low-level format or you may cause serious damage to the drive.  
To use an IDE drive, you need to enter the drive type (this information  
is provided by the drive manufacturer) into the system’s CMOS setup  
table. Then run FDISK and FORMAT provided with DOS. You may also  
use the IDE HDD Auto Detection function which will allow the BIOS to  
auto detect your hard drive type. Refer to the IDE HDD Auto Detection  
section for details.  
Warning:  
Do not run FDISK and FORMAT programs on a drive that has already  
been formatted or you will lose all programs and data stored on the  
drive.  
Using 586IVX with CD-ROM Drives  
If you encountered problems while using an ATAPI CD-ROM drive that  
is set in Master mode, please set the CD-ROM drive to Slave mode.  
Some ATAPI CD-ROMs may not be recognized and cannot be used if  
incorrectly set in Master mode.  
Universal Serial Bus Connectors  
The 586IVX system board is equipped with two USB ports on locations  
J2 and J4 on the system board. USB allows data exchange between  
your computer and a wide range of simultaneously accessible peripher-  
als. Make sure “USB Controller” in the Integrated Peripherals setup of  
the Award BIOS is set to Enabled.  
29  
Installing Expansion Cards  
The 586IVX system board is equipped with 3 dedicated PCI slots, 3  
dedicated 16-bit ISA slots and 1 shared PCI/ISA slot. All PCI slots are  
bus masters. Refer to page 12 for the locations of the expansion slots.

Power Management  
This category allows you to select the type (or degree) of power saving  
by changing the length of idle time that elapses before each of the  
following modes are activated: Doze Mode, Standby Mode, and Sus-  
pend Mode.  
Disable  
(default)  
No power management. Disables the Doze, Standby and  
Suspend modes.  
Min. Power Minimum power management. Doze Mode = 1 hr., Standby  
Saving Mode = 1 hr., and Suspend Mode = 1 hr.  
Max. Power Maximum power management. Doze Mode = 1 min.,  
Saving  
Standby Mode = 1 min., and Suspend Mode = 1 min.  
User  
Defined  
Allows you to set each mode individually. When enabled,  
each option ranges from 1 min. to 1 hr.  
41  
PM Control by APM  
Yes  
No  
An Advanced Power Management device will be activated to  
enhance the Max. Power Saving mode and stop the CPU’s  
internal clock. Use this option in Windows 95. (default)  
The system BIOS will ignore APM when initiating the Power  
Management mode.

This option only writes blanks to the video buffer.  
DPMS  
Initializes display power management signaling. Use this option  
if your video board supports it.  
MODEM Use IRQ  
This category is used to set an IRQ channel (IRQ 3, 4, 5, 7, 9, 10 or  
11) for the modem installed in your system.  
Doze Mode, Standby Mode, Suspend Mode and HDD Power Down  
These Green PC power saving categories are user configurable only  
when the Power Management category is set to User Defined.  
Doze  
Mode  
When enabled and after the set time of system inactivity, the  
CPU clock will run at a slower speed (1/2 of full speed) while  
all other devices still operate at full speed.  
Standby When enabled and after the set time of system inactivity, the  
Mode  
CPU clock will run at a speed slower than the speed during  
Doze mode (1/3 of full speed) while all other devices still oper-  
ate at full speed.  
Suspend When enabled and after the set time of system inactivity, the  
Mode CPU and onboard peripherals will be shut off.  
42  
HDD  
Power  
Down  
This is used to define the continuous HDD idle time that  
elapses before the HDD enters the power saving mode (motor  
off). When enabled and after the set time of system inactivity,  
the hard disk drive will be powered down while all other de-  
vices remain active.  
IRQ3-IRQ15 (Wake Up Events in Doze & Standby and Power  
Down & Resume Events)  
These are I/O events whose occurrence can prevent the system from  
entering a power saving mode or can awaken the system from such a  
mode. In effect, the system remains alert for anything which occurs to a  
device which is configured as enabled, even when the system is in a  
power saving mode.  
When an I/O device wants to gain the attention of the operating system,  
it signals this by causing an IRQ to occur. When the operating system  
is ready to respond to the request, it interrupts itself and performs the  
service.  
PNP/PCI Configuration  
This section describes configuring the PCI bus system. It covers some  
very technical items, and it is strongly recommended that only experi-  
enced users make any changes to the default settings.

Hard Drive Mode  
The system board supports three HDD modes: Normal, LBA and Large.  
If your hard disk drive does not support LBA mode, the “LBA” option will  
not be displayed. If your HDD has 1024 or fewer cylinders, the “Large”  
option will not be displayed. If your hard drive is larger than 2.1GB, be  
sure that your operating system supports it or you may need to create  
separate partitions.  
Normal Mode  
Normal mode is the generic access mode in which neither the BIOS nor  
the IDE controller will make any transformations during hard-drive ac-  
cess.  
The maximum number of cylinders, heads and sectors for Normal mode  
are 1024, 16 and 63, respectively.

50  
If you set your HDD to Normal mode, the maximum accessible HDD will  
be 528 megabytes even though the physical size of the HDD may be  
greater than that.  
LBA (Logical Block Addressing) Mode  
LBA mode is a HDD accessing method to overcome the 528 megabyte  
limitation. The number of cylinders, heads and sectors shown on the  
screen may not be the actual number for the HDD.  
During HDD accessing, the IDE controller will transform the logical ad-  
dress described by the sector, head and cylinder number into its own  
physical address inside the HDD.  
The maximum HDD size supported by the LBA mode is 8.4 gigabytes. It  
is obtained by the following formula.

Large Mode  
Large mode is the extended HDD access mode supported by the sys-  
tem board. Some IDE HDDs have more than 1024 cylinders without  
LBA support (in some cases, you may not want the LBA mode). This  
system board provides another alternative to support these kinds of  
HDDs.  
The BIOS tells the operating system that the number of cylinders is half  
the actual number and that the number of heads is double the actual  
number. During disk access, the reverse conversion is done by the  
INT13h routine.

Note:  
To support LBA or Large mode, address translation software is included  
in the Award BIOS HDD Service Routine (INT13h). If you are running  
an operating system that bypasses the BIOS INT13 Service Routine,  
LBA and Large Mode may fail.

Desktop Management Interface (DMI)  
The 586IVX system board comes with a DMI built into the BIOS. DMI,  
along with the appropriately networked software, is designed to make  
inventory, maintenance and troubleshooting of computer systems  
easier. With DMI, a network administrator or MIS engineer can remotely  
access some information about a particular computer system without  
physically going to it. Quite often a service call may be unnecessary as  
the problem can be solved remotely.  
The DMI utility in the BIOS automatically records various information  
about your system configuration. Information about the type and speed  
of CPU, type and amount of memory for each memory slot, BIOS revi-  
sion level, types of add-in PCI boards and components, certain revision  
numbers of hardware installed, etc. are automatically detected and  
stored in the DMI pool, which is a part of the system board's Plug and  
53  
Play BIOS. Additional information, such as ISA based peripherals,  
which may not be automatically detected, can be manually recorded in  
the DMI pool by using the Add DMI menu. The DMI pool data is then  
verified or updated whenever the system hardware or setup is altered.  
Running the DMI Utility  
To run the DMI utility, type: DMICFG.EXE. You can download this utility  
from http://www.dfi.com.tw- BIOS & DRIVERS section or ftp.dfiusa.com -  
/pub/DMI directory.  
The DMI utility must run in real mode with at least 180K of base  
memory. Memory managers like HIMEM.SYS (required by Windows)  
must not be installed. To do this, boot up from a system diskette without  
the AUTOEXEC.BAT and CONFIG.SYS files. “REM” HIMEM.SYS in the  
CONFIG.SYS or press <F5> during bootup to bypass your  
AUTOEXEC.BAT and CONFIG.SYS files.

Chapter 4  
Troubleshooting Checklist  
This chapter of the manual is designed to help you with problems that  
you may encounter with your personal computer. To efficiently  
troubleshoot your system, treat each problem individually. This is to  
ensure an accurate diagnosis of the problem in case a problem has  
multiple causes.  
Some of the most common things to check when you encounter  
problems while using your system are listed below.  
1. The power switch of each peripheral device is turned on.  
2. All cables and power cords are tightly connected.  
3. The electrical outlet to which your peripheral devices are connected  
is working. Test the outlet by plugging in a lamp or other electrical  
device.  
4. The monitor is turned on.  
5. The display’s brightness and contrast controls are adjusted properly.  
6. All add-in boards in the expansion slots are seated securely.  
7. Any add-in board you have installed is designed for your system and  
is set up correctly.  
Monitor/Display  
If the display screen remains dark after the system is turned on:  
1. Make sure that the monitor’s power switch is on.  
2. Check that one end of the monitor’s power cord is properly attached  
to the monitor and the other end is plugged into a working AC outlet.  
If necessary, try another outlet.  
3. Check that the video input cable is properly attached to the monitor  
and the system’s display adapter.  
4. Adjust the brightness of the display by turning the monitor’s  
brightness control knob.  
59  
Hard Drive  
Hard disk failure.  
1. Make sure the correct drive type for the hard disk drive has been  
entered in the BIOS.  
2. If the system is configured with two hard drives, make sure the  
bootable (first) hard drive is configured as Master and the second  
hard drive is configured as Slave.  
Excessively long formatting period.  
1. If your hard drive takes an excessively long period of time to format,  
it is likely a cable connection problem.  
Parallel Port  
The parallel printer doesn’t respond when you try to print.  
1. Make sure that your printer is turned on and that the printer is on-  
line.  
2. Make sure your software is configured for the right type of printer  
attached.  
3. Verify that the onboard LPT port’s I/O address and IRQ settings are  
configured correctly.  
4. Verify that the attached device works by attaching it to a parallel port  
that is working and configured correctly. If it works, the printer can  
be assumed to be in good condition. If the printer remains  
inoperative, replace the printer cable and try again.  
Serial Port  
The serial device (modem, printer) doesn’t output anything or is  
outputting garbled characters.  
1. Make sure that the serial device’s power is turned on and that the  
device is on-line.  
2. Verify that the device is plugged into the correct serial port on the  
rear of the computer.  
60  
3. Verify that the attached serial device works by attaching it to a serial  
port that is working and configured correctly. If the serial device  
does not work, either the cable or the serial device has a problem. If  
the serial device works, the problem may be due to the onboard I/O  
or the address setting.  
4. Make sure the COM port settings and I/O address are configured  
correctly.  
Keyboard  
Nothing happens when a key on the keyboard was pressed.  
1. Make sure the keyboard is properly connected.  
2. Make sure there are no objects resting on the keyboard and that no  
keys are pressed during the booting process.  
System Board  
1. Make sure the add-in card is seated securely in the expansion slot.  
If the add-in card is loose, power off the system, re-install the card  
and power up the system.  
2. Check the jumper settings to ensure that the jumpers are properly  
set.  
3. Verify that all SIMMs are seated securely into the SIMM sockets.  
4. Make sure the SIMMs are in the correct locations.  
5. If the board fails to function, place the board on a flat surface and  
seat all socketed components. Gently press each component into  
the socket.  
6. If you made changes to the BIOS settings, re-enter setup and load  
the BIOS defaults.
