Broken Motherboard Pins

My intel tells me this is the motherboard for an eMachines T3642 Desktop PC,

http://www.ebay.com/itm/GATEWAY-EMACHINES-W3644-MCP61SM2MA-4006232R-MOTHERBOARD-T5246-T3646-T3642-S3649-/330737918167?pt=Motherboards&hash=item4d018420d7

If this holds true,

http://support.gateway.com/s/MOTHERBD/Shared/4006232R/4006232Rnv.shtml

In the list click on the blue - Product Views

The Ebay link shows you where the letters, of the above Gateway link, are on the motherboard.

1) B - Auxiliary 12 Volt ATX connector.
This is where the 4-pin ATX +12 Volt power cable plugs in,

Example of power cable from Power Supply,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

Power for the Processor (CPU) Do NOT forget it.

2) E - Main Power Connector

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

Note* Color of connectors for 1) above, and 2), do NOT matter.
What the connector is, Does.

Note also that there is a pivoting Lock, on both power cable connectors.
The matching motherboard connector has a Lock TAB.
When the power cables are deemed to be plugged in tightly, and correctly; the Lock's hooked end will be over the Lock Tab.

[Squeeze the top of the Lock in, to release. Release when removing.
The Lock works on the same action as a seesaw on a playground ]

3) F- Floppy Disk Drive Connector
A 34 wire thin ribbon IDE cable, connects here on the motherboard, and plugs into the back of the Floppy Drive. The cable is the Data cable.

The power cable that goes to it is a 4-pin Small peripheral power cable. Looks like this example,

http://www.playtool.com/pages/psuconnectors/connectors.html#floppy

IF a Memory Card Reader, (Media Card Reader. Same/same) is used instead; it will use the SAME power cable.

The data cables are different though. They connect to a Front USB header on the motherboard, and are a rounded cable.

ONE of the Front USB headers on the motherboard, will be used for the Card Reader.
Click on S - USB 2.0 Connectors

[NOTE* In EACH USB header are provisions for attaching to TWO USB ports. Front OR back of computer.
One will be used for the TWO data cables, going to the Card Reader. Which one? Pick one.
BIOS will set up a new Interrupt Request for it. (IRQ) ]

G - Parallel ATA IDE Connector
40 wire flat ribbon data cable goes here. (ONLY 39 wires are actually used, though)

http://en.wikipedia.org/wiki/File:PATA-cable.jpg

http://en.wikipedia.org/wiki/File:ATA_cables.jpg

Now I'm going to get a little lengthy, and detailed;

In the first link immediately above, PATA-cable.jpg
See the two small 'ribs' on the Top/Middle of the connector?
(May just be one solid block, also)

That is a Locating Lug. When you plug the connector into the motherboard, it lines up with a Cutout in the motherboard connector.
IF there is NO Locating Lug;
Look at the side of the cable that has the faint Red stripe.
This Red stripe is on the SAME side as Number 1 wire.

When plugging into the motherboard connector, the side of the cable that has the Red stripe, goes DOWN. Down towards the Bottom of the motherboard.
Number 1 pin in the motherboard connector, is at the Bottom of the motherboard connector.

If no Locating Lug when plugging into a device; Harddrive or Optical Drive, (CD/DVD drive);
The side of the flat data ribbon cable that has the Red stripe, goes towards the POWER CABLE pins, on the device.

Let's look at an IDE (PATA) harddrive, and the 4-pin Peripheral power cable that plugs into it;

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

See where the power cable plugs in? The Red stripe on the IDE flat ribbon cable, will be next to the power cable.
Also can be said as, when the IDE flat ribbon cable is plugged into the Harddrive, the Red stripe will be on the Right.

Same with an Optical Drive.

You MAY have an optical drive's flat data cable plugged in here.
IF it is an IDE (PATA) optical drive.
MORE than likely though, your Harddrive is a SATA unit, and plugs into a SATA connector on the motherboard.

U - SATA Connectors
Note there are two. SATA1 and SATA2.
The Harddrive is supposed to plug into SATA1.
The beauty of SATA is though, that you can plug the Harddrive into SATA1, OR SATA 2.
BIOS will find the device.

This is an example of a SATA data cable, and it's connector,

http://en.wikipedia.org/wiki/File:SATA_ports.jpg

(Your SATA connector on the motherboard, is different than the example shown)

Between a SATA data cable's connector, and a SATA power cable's connector; a SATA power cable connector is the Larger of the two.
A SATA data cable connector has 7-PINS.
A SATA power cable connector has 15-PINS.

Note also the L-shaped opening. This lines up with an L-shape on the Harddrive connector, or an Optical Drive connector. (Data cable connector)
Note also that a SATA power cable has this same L-shaped opening.

,to the right of the red Adobe PDF icon.

There is your motherboard manual.

I reduced the view size to 75 percent, with the Zoom Out icon ( - ) at the top.
Use the Down Arrow, and go to Page 5. (Adobe Reader page number at top, to the right of the Down Arrow)

Motherboard Layout

Motherboard view shown is actually turned 90 degrees to the Right, in reality to how it actually is mounted in a computer case.

The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the main wires from the Front Panel go to, is the Front panel header.

Motherboard installed in computer case, the Front Panel header is to the Right of the CMOS battery, and located in the Bottom/Right corner, placed in a Vertical position.

Two columns of contact pins.
4 in the Left column, 5 in the Right column.

The pins on the Left side are numbered EVEN.
The pins on the Right side are numbered ODD.

Starting at the BOTTOM coming up towards the Top; Left side,
Pins 2, 4, 6, and 8. There is NO Pin 10.

Starting at the Bottom coming up towards the Top; Right side,
Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the HarDDrive activity LED. (Light)
Pin 1 is for the Positive wire.
If the HDD LED is dim when the harddrive is active, switch the wires around.

B) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.

C) Pin 9 is N/C. Not Connected. Probably 5 Volts + for factory testing.

D) Pins 2 and 4 are for the Power On LED. (Light)
(Light Emitting Diode)
Pin 2 is for the Positive wire.
If the PWR LED is dim when the computer is on, switch the wires around.

E) Pins 6 and 8 are for the Power On switch.

F) There is NO Pin 10.

Just a start. Do you need what CPU's are supported?

1) Intel Pentium 4, Socket 478 processors that are either Willamette Core, or Northwood Core processors.

A) 400Megahertz Front Side Bus (400MHz FSB)

B) Up To a 2.8GigaHertz (2.8GHz), Socket 478 -> Northwood Core - processor.

(Motherboard manual shows specs for using Intel Celeron's, that use a Socket 478 processor socket, but WHO cares?
'Celeys' aren't worth bothering with )

Starting with Willamette Core. Northwood Core processors are in the next chart. (Socket 478)

The motherboard chipset is a Northbridge chip, and a Southbridge chip,

http://en.wikipedia.org/w/index.php?title=File:Motherboard_diagram.svg&page=1

(CPU = Central Processing Unit. Another term used is Microprocessor, or Processor for short)

The Northbridge chip is a SiS650GX
The Southbridge chip is a SiS 962L, or SiS 962,

http://www.motherboards.org/mobot/chipsets_d/SiS/650GX+962L/

Install Processor first. (Remember to line up the Processor's; Dot/s, or Arrow/s with the processor socket's Dot/s or Arrow/s)
Thermal Paste correctly applied, Heatsink set properly. (F-L-A-T)

Plug Processor fan power wire into motherboard.
(White 3-pin connector to the Top Left corner of the Processor socket, and close to the top edge of the motherboard.
CPU_FAN)

Install Ram Memory.
Install motherboard on Support Plate.

The Support Plate can be a separate metal plate, or is part of the computer case.
When mounting the motherboard to the Support Plate, and NOT using plastic Spacers, but ARE using metal Standoff's;

,make SURE that EVERY Standoff is matched up, to a mounting hole in the motherboard.

IF, there is a Standoff not matched up to a mounting hole, there is a good chance it will touch an exposed solder joint on the bottom of the motherboard, and short the motherboard out.
(Maybe Processor, Ram Memory, graphics card if used, too )

On the back of the computer tower is a thin metal rectangular plate.
This is the I/O area, and the I/O Static Shield.
I/O stands for Input/Output.
Input devices and Output devices are connected in this area.
Mouse, Keyboard, Speakers, etc.

Every motherboard is supposed to come with it's own I/O Static Shield. If there is one already present remove it, use the one that came with the motherboard.
(Watch the edges! May be SHARP!)

Motherboard is installed tilted at an angle, I/O ports down.
Then I/O ports going slightly through the I/O Static Shield, the opposite side is brought down.

Two power cables from the Power Supply to motherboard;
1) 24-pin ATX main power cable;

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

(Note* Color of connectors does NOT matter)

Plugs into the 24-pin ATX main power cable connector, to the right side of the Ram Memory slots.

2) 4-pin ATX +12 Volt power cable;

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

Below the processor socket is the Northbridge chip. It is under that finned aluminum Heatsink, with Foxconn on it.
To the Left is a small 4-socket hole whitish connector.
This is the 4-pin ATX +12 Volt power cable connector, on the motherboard.

The Floppy Disk Drive flat ribbon IDE data cable, goes to the Black 34-pin connector to the Right; of the 24-pin ATX main power cable connector, on the motherboard.

Uses this Small 4-pin Peripheral power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#floppy

(WATCH the contact pins on the Floppy Drive, for the power cable. They are Sharp as NEEDLES, and will stab you! They BEND real easy too!)

The Harddrive's flat IDE ribbon cable connects to the BLUE 40-pin connector, below the Black Floppy Drive connector.

BOTH, a Floppy Drive flat ribbon cable's connector, and a Harddrive flat ribbon cable's connector, and an Optical Drive flat ribbon cable's connector; have a LUG on one side.

This Lug is to match up with a small square Cutout, in the motherboard's matching connector.

The harddrive, and optical drive should have a square Cutout, in the circuit board.

IF, the cable connectors do Not have a Lug, or there is no Cutout on the Harddrive, or Optical Drive; post back in a Comment, and I'll detail how to correctly hook them up.

USB Headers: F_USB on the motherboard is for using TWO USB ports, in the Front Panel. (Page 22)

Audio Connectors (CD_IN) Page 23, is for the small audio cable that comes from the Main optical drive.
IF, you have two optical drives, use the one you consider the Main one, and attach the CD_IN (Audio cable) to CD_IN on the motherboard.
This connector is to the immediate Left of the number 2 and 3 white PCI slots.

REMEMBER, follow Anti-Static Precautions.

Ya know Acer owns Gateway now,

http://support.gateway.com/s//MOTHERBD/Shared/4006233R/4006233Rnv.shtml

A) Power Supply to motherboard cabling;

http://www.ebay.com/itm/ECS-MCP61SM-AM-V-1-0A-SOCKET-AM2-AMD-MOTHERBOARD-uATX-/290606277901

Scroll down to the motherboard top view photo.

Product Views > Hardware Details

1) 24-pin ATX main power cable. (S - Main Power Connector)

This is a general example of a 24-pin ATX main power cable, and it's respective connector on the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

[Note color of connectors does NOT matter ]

Note the Lock on the side of the main power cable's connector, and the matching Tab on the motherboard connector. When properly plugged in, the hooked end of the Lock will be over the Tab, on the motherboard connector.

In the photo of the motherboard shown on the Ebay link, this connector is on the Right side of the motherboard, next to the blue IDE (PATA) connector.

2) 4-pin ATX +12 Volt power cable; (F - Auxiliary 12V ATX Connector)

General example of a 4-pin ATX +12 Volt power cable, and it's respective connector on the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

In the motherboard photo; Small square 4-socket hole connector, to the Bottom/Left corner of the Processor socket.

This power cable's connector also has a Lock, and the motherboard connector has a Tab.

That's all the power cables that go to the motherboard.

B) With 2 SATA headers (Connectors) on the motherboard, and one IDE (PATA) connector, it suggests to me that this motherboard is set up to use a SATA harddrive.

This is a general example of a SATA power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

Note that it has 15 contact pins, and between it, and the SATA data cable connector, it is the larger of the two.
There is a Lock tab on the connector that you depress, to install, or remove the cable.

You can use a SATA optical drive (CD/DVD drive), or an IDE (PATA) optical drive.
An IDE (PATA) optical drive uses a standard 4-pin Peripheral power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

[ Misnomered as a 'Molex' power cable. Molex was the first to make the power cable's connector. Name stuck, kind of like calling an open-end wrench a Crescent wrench ]

A SATA data cable is used for the SATA harddrive. The connector end that goes to the Harddrive, is usually a 90 degree bent elbow.
The straight end plugs into the motherboard,

General example of a SATA data cable, and it's corresponding connector on the motherboard,

http://en.wikipedia.org/wiki/File:SATA_ports.jpg

Note the L-shape in the inside of the SATA data cable's connector, and the L-shape on the motherboard connector. They line up.
The SATA power cable also has this L-shape.

In Hardware Details click on -> Q - SATA Connectors
The Bottom one, or one closest to the outside edge of the motherboard, is SATA1.

Although it isn't marked on the motherboard, or at least not visible in this photo, SATA 4 is. Look at the top where a SATA 4 connector would be.
The SATA harddrive should be plugged into the SATA1 header.
(Connector)

HOWEVER, the beauty of SATA is that it does NOT matter, which SATA header on the motherboard, you plug the SATA harddrive into.

BIOS will find it.

(Supposed to be SATA harddrive to SATA1, and a SATA optical drive to SATA2)
In the motherboard photo on Ebay, they are Orange in color, and under the blue IDE (PATA) connector.

C) Going from Hardware Details and the Ebay motherboard photo;

B - CPU Fan 1 Connector, is where the Processor fan plugs in.
In the motherboard photo, there are 7 cylindrical Electrolytic Capacitors in a row, to the left of the processor socket.

This connector is located immediately above the top capacitor, near the outside edge of the motherboard. (Brown in color)

E - Floppy Disk Connector, is above the white 24-pin ATX main power cable's connector, and the blue IDE (PATA) connector. It is Yellowish in color. (34 pins)

G - System Fan Connector, is white in color, has 3 contact pins, and is located under the white, square 4-pin ATX +12 Volt power cable connector. This is where the computer case fan plugs in.

I - PCI Express x16 Connector, is Orange in color, and below the processor socket. It has PCI Express silkscreened on the motherboard immediately below it.
This where a graphics card, and ONLY a graphics card, is installed.

J - PCI Express x1 Connector, is white in color, and immediately below the orange PCI Express x16 connector.
This is NOT used for a graphics card.

Whatever you can use in a PCI slot, except a graphics card, can be used in this slot; -> Provided it is a PCI Express x1 card.
(Ethernet Card, Sound Card, etc)

L - CD-in Connector is where the audio cable from the Main (Primary) optical drive goes to.
Ya got me on this one. I know it's located real close to the Realtek audio chipset, and I think that is to the left of the orange PCI Express x16 slot.

M - Front Audio Connector, is where the front audio (Sound) ports, of the Front Panel connect to.
Green in color, and located under the bottom white long PCI slot, and near the outside edge of the motherboard.

N - Clear CMOS Jumper is self explanatory. It is located under the finned Heatsink, (Looks like a meat tenderizer), of the Southbridge chip.
(Which is located under the Ram Memory slots)

O - USB Connectors are Yellow in color, and located under the finned Heatsink of the Southbridge chip, and towards the outside edge of the motherboard. (Or also located under the Ram Memory slots)

P - Front Panel Connector, is located at the Bottom/Right corner of the motherboard, close to the 'Buzzer'. (Buzzer is used for BIOS Beep Codes) PANEL1

4 pins on the Left side, 5 pins on the Right side.
The pins on the Left side are numbered EVEN.
The pins on the Right side are numbered ODD.

Starting on the Bottom of the Left side going Up;
Pins 2, 4, 6, 8, and 10.

Starting on the Bottom of the Right side going Up;
Pins 1, 3, 5, and 7

A) Pins 1 and 3 are for the HarDDrive activity LED. (Light)
Pin 1 is for the Positive ( + ) wire.
If the HDD LED is dim when the harddrive is active, switch the wires around.

B) Pins 5 and 7 are for a Reset switch. IF a Reset switch is used.

C) Pin 9 is Not Connected. Used by the factory.

D) Pins 2 and 4 are for the Power On LED. (Light)
Pin 2 is for the Positive ( + ) wire.
If the PWR LED is dim when the computer is on, switch the wires around.

E) Pins 6 and 8 are for the Power On switch.

More to follow.

http://h10025.www1.hp.com/ewfrf/wc/product?product=3688725&lc=en&cc=us&dlc=en&lang=en&cc=us

Ready for a long read?

A) Power Supply /Motherboard

Motherboard with no hardware components installed, nor cables attached,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01321559&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=3688725

I also would like you to scroll down a little further, and click on the + sign to the left of - Motherboard layout.
Shows an illustration of the motherboard.

1) 24-pin ATX main power cable:
Looking at the motherboard illustration (Motherboard layout), look at the Top/Middle.
ATXPWR1 is where the 24-pin ATX main power cable plugs in.

In the photo you see - ATXPOWER and CPU_FAN above this black connector.

[ Processor fan {CPU Fan}, is the first white 4-pin connector, to the right of the black 24-pin ATX main power cable connector.

A Chassis, {Computer case} fan plugs into the next 3-pin brown header to the right.
That was the only space the motherboard manufacturer had, to mark the motherboard for those two connectors ]

This shows a general example of this type of power cable.
(Note color does NOT matter),

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

Note the Lock on the side (Middle) of this power cable's connector.
Also note the matching Tab on the motherboard connector.

The Lock operates like a see-saw on a playground. The top is squeezed in to bring the hooked end of the Lock, away from the Tab on the motherboard connector.
When this power cable is deemed to be plugged in properly, and tightly, the Lock's hooked end will be over the Tab.

That concludes the power cables coming from the Power Supply, to the motherboard.

B) Power Supply / Peripherals:

The Harddrive is a SATA unit. 500GigaByte, and has a 7200 RPM spindle speed.
There is a SATA power cable that plugs into it.
General example of a SATA power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

Note that a SATA power cable has 15 contact pins. It is the longer of the connectors when comparing to a SATA data cable connector.
(7 pins)

The optical drive (CD/DVD burner that has LightScribe technology), is a SATA unit also. Uses a SATA power cable.

A) Data Cables:
The Harddrive, and optical drive require a SATA data cable.
General example of a SATA data cable, and SATA data connector on the motherboard,

http://en.wikipedia.org/wiki/File:SATA_ports.jpg

Note the SATA connector on the SATA data cable.
Has an L-shape on the inside. Lines up with the L shape on the motherboard connector, and Harddrive and optical drive connector.

The red connector shown is a SATA data cable connector, on the motherboard.
Looking back at the HP Support page, look at the illustration.
(Motherboard layout)

The Ram Memory slots are designated by XMM1 and XMM2.
To the bottom left of them are the two SATA data connectors.
SATA 1 and SATA 2.

In the motherboard photo you can see they are plainly marked.
SATA 1 is White, SATA 2 is Black.
The Harddrive plugs into SATA 1.
An optical drive will plug into SATA 2.

Most of the time a SATA data cable will have a 90 degree bent elbow, for plugging into the Harddrive, and Optical Drive.
The straight connector end plugs into the motherboard.

A) Processor Fan and Chassis Fan:
I have already stated where the processor fan plugs in, and the Chassis (Computer case) fan plugs in.

A) USB Front Panel:
The Front Panel is the front of your computer. The USB headers on the motherboard, USB1 and USB4, are where the front USB ports plug into.
These headers (Connectors) are to the right of the SATA data connectors. (F_USB1 and F_USB4)

A) Front Audio:

The long Black slot at the bottom of the motherboard, is a PCI-Express x16 slot. Used for a graphics card.
To the left of it is the Front Panel audio connector.
F_AUDIO1, and is Yellow in color.

A) Front Panel header:

As stated the front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the main wires go to, is the Front panel header.

On the motherboard illustration it is at the Bottom/Right, and marked as F_PANEL1

Horizontal header, and two rows of contact pins.
4 on the Top row, and 5 on the Bottom row.

IF, I have this pinout correct;

Pins on the Top row are number EVEN.
Pins on the bottom row are numbered ODD.

Starting on the LEFT side coming towards the Right, Top row;
Pins 2, 4, 6, and 8. There is No Pin 10.

Starting on the LEFT side coming towards the Right, Bottom row;
Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the HarDDrive activity LED. (Light)
Pin 1 is for the Positive ( + ) wire.
If the HDD LED is dim when the Harddrive is active, switch the wires around.

B) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.

C) Pin 9 is N/C. Not Connected. (It's a 5 Volt power wire used for factory testing )

D) Pins 2 and 4 are for a Power On LED. (Light)
Pin 2 is for the Positive ( + ) wire.
If the PWR LED is dim when the computer is on, switch the wires around.

E) Pins 6 and 8 are for the Power On switch.

F) There is No Pin 10.

Hopefully you just have a cable with a connector on the end, that plugs into the Front Panel header.
Same with your Front Panel USB ports, and Front Panel audio ports.

After you have hooked up all cables, and deem to be finished, take the Ram Memory module/s ('Stick') out, and reinstall.
Most of the time they get bumped loose, and you CANNOT see by a visual inspection if they are.

Best method is to just remove them/it, and reinstall. This way you are ASSURED they are seated, and tight.

I Hope you have been FOLLOWING Anti-Static Precautions.
If not plan on using your motherboard, Processor, Ram Memory, Graphics card(?), and harddrive, for an expensive paperweight.

Anti-Static Precautions:
Your body carries Static electricity. Static WILL fry out (Short Circuit) the delicate hardware components inside a computer.

Relieve your body of Static electricity BEFORE reaching inside your unplugged from power computer, or removing any new parts out of their anti-static bags, or cartons.

Computer on a table, computer unplugged from power, computer case open;
TOUCH an unpainted surface, of the metal framework of the open computer case.
This action will relieve your body of Static.

IF you leave your computer in the middle of working on it, be SURE to Touch the metal frame again upon your return.

For additional questions please post in a Comment.

(You do have that computer laying on it's side, right? Much easier to work on. I use a static free, clean towel on the table, to protect the table, and the computer case )

Okay,.......that was DU-MB!

Lemme see,.......oh yeah!

Letters and words! !O_O!

(Wondered where my glasses were!)

Motherboard photo, and detailed info below it. Scroll down.

Looking at the motherboard installed in the computer case:

1) To the right of the Ram Memory slots, and in the upper right corner, is the 20-pin ATX main power cable connector, on the motherboard.

Whitish connector with two columns of 10 socket holes.
A 20-pin ATX main power cable plugs in here,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

Note the Lock on the side of the power cable's connector, (Middle photo, and right photo), and the Tab on the motherboard connector, (Left photo)

When the power cable is plugged in correctly, the hooked end of the Lock on the power cable's connector, will be hooked over the Tab on the motherboard connector.

2) Look at the bottom Left corner of the Processor socket. Note the three cylindrical objects. (Radial Aluminum Electrolytic Capacitors)
Note the whitish square 4-socket hole connector below them.

This is where the 4-pin ATX +12 Volt power cable goes. It also has a Lock, just like the 20-pin ATX main power cable connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

This is power for your Intel Pentium 4 processor.

3) To the Right of the Ram Memory slots, and located below the whitish 20-pin ATX main power cable connector, are the two IDE connectors. (Turquoise Blue)

One is for an IDE (PATA) harddrive, and one is for an IDE(PATA) optical drive. (CD/DVD drive)

The one on the outside near the edge of the motherboard, has IDE1 next to it.
It is for the Harddrive.
The one closer to the middle of the motherboard is IDE2.
It is for the optical drive. (Or drives { 2 } )

NOTE*
One side of those rectangular connectors has a cutout in the middle.
(Square U-shape cutout)
This is where the Locating Lug, on the flat ribbon IDE cable's connector, goes to.

It aligns Number 1 pin in the connector, with Number 1 wire, in the flat ribbon IDE cable.

IF, there is NO Locating Lug on the flat ribbon IDE cable;

On one side of the flat ribbon IDE cable is a thin RED stripe.
This stripe denotes the side that Number 1 wire is on,

Looking at the rectangular IDE1 and IDE2 connectors, Number 1 pin is at the BOTTOM of those connectors.
(Motherboard installed in computer case)

On an IDE harddrive, Number 1 pin is ALWAYS towards the 4-pin power connector.
Same with an optical drive.

4) Since this is a motherboard, that has a RAID option for using multiple harddrives, I'm guessing the two Yellow rectangular connectors, below the two rectangular Turquoise Blue IDE connectors, is for more IDE harddrives.

5) Below the two Yellow IDE harddrive connectors is a Black rectangular connector.
This has 34 pins, and is for a Floppy Drive, IF a Floppy drive is used.

6) Below the Black Floppy Drive connector on the motherboard, is the Front Panel header.

The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the main wires from the Front Panel go to, is the Front Panel header.

What is needed here is a Front Panel header pinout.

Dunno. Photo isn't clear enough.
Looks like a Black rectangular strip of plastic, with 8 pins in a row.
4 pins, 3 spaces, 1 pin, 1 space, 3 pins.

Looking closely, (And you may need a bright light, and a magnifying glass), what are the abbreviations next to the pins, on the outside edge of the motherboard?

HDD = HarDDrive activity LED (Light)
PW = Power On switch
RST = Reset switch
PWLED, or close to that effect = Power On LED.

Post back in a Comment.

IF, it is just a row of single pins going across, I would use an LED light that has two wires on it.

Computer, (Power Supply actually), plugged into power, touch the two wires to the first two pins.
Nothing?
Go on.

When the Power Supply comes on you know you have the Power On switch pins (2)

Now go back through, but do not touch those pins again.
LED light blinks? = HarDDrive activity LED (Light)
LED light stays on? = Power On LED (Light)
Computer restarts? = Restart switch pins

7) To the left of the white long PCI slots, (There are 5 towards the bottom of the motherboard), are two small Black rectangular connectors. Each has 4 pins in it.

The one that has Audio, or CD, or CD-IN, is for the audio cable from the CD/DVD drive.

8) At the Top of the motherboard in-between the Processor socket, and black Ram Memory slots, is an Orangish connector with 3 pins. Should have CPU, or CPU_FAN next to it. This is where the Processor fan plugs in.

9) At the bottom/left, and below the two small black connectors with 4 pins in them, is an Orangish connector with 3 pins.
This should be for the computer case fan.
(SYS_FAN)

Additionally you may want to join this website, and ask them for the Front Panel header pinout, for your Abit BD711 motherboard,

http://www.theraptorpit.com/forum/index.php?/forum/124-abit-motherboard-tech-support-unofficial/

Finding information for an ABIT BD711 motherboard, is about as rare as finding hen's teeth.
I, and I'm sure 100's of people, would be in your debt, if you would post the Front panel header pinout for this motherboard.

Hope I have redeemed myself for the S.N.A.F.U. of the question asked in the Comment, lol!

Not too much way you can go wrong. There's a 20 or 24-pin connector which plugs into the motherboard in only one place. There probably is a 4-pin connector and that, too, goes into the motherboard (in a socket near the CPU). The other connectors are power connectors for you hard drive and CD/DVD. That's about it.

You must check cable(small) one the (left or right) one hard drive, CD Drive, floppy disk and for motherboard (the big one) .You check the manuals, is not hard just follow where the power lines.

I suggest you replace the motherboard. A recent search on ebay turned up three ranging in price from $18 to $85. Soldering a motherboard by hand has a very high failure rate. It's easy to bridge or scratch something and fry the board. You could of course try to do it and if it fails get a replacement board.

soldering iron and a whole lotta luck. floppy's drives (3.5 inch and 5.25 inch) are not rated in terms of IDE scooter!

get into the bios F2 or Del on boot up and change the first boot device to cdrom and 2nd to HDD then last the 'a' drive. The floppy drive may be faulty, if you dont use it just disconnect it.
