You can download the manual for the motherboard here, just click on the "manual" link:

http://www.biostar.com.tw/app/en-us/mb/driver.php?S_ID=246

This will list the front panel connections, which are 2 pins. Each of the jumpers, what you are calling clips, will connect two of the pins. Most cases have the jumpers labeled, i.e. power, reset, etc. But if they are not, it is usually: red/white = HDD led; green/white = power led; red/black = speaker; black/green = power switch; and black/white = reset. But your case may use a different wiring spec, but should list somewhere which wire is for which function.

    In many cases it does not matter, for example, assuming one is a reset (and unless the case has a reset button on the outside, it does not, and that may be why you only have 3 wires when there are normally more).

    However, it should be easy enough to figure out which is which. Just start with the black and white, and connect it to the power pins. When you press the power button on the front, if you have it right, the computer will turn on. If not, try reversing the pins, and try again. If it does not power up, then we have the wrong cable, and can try one of the others until it works properly.

    Since you have only 3 connections, I believe one is the power switch, one is the power light (this one does matter which way it goes), and the HDD light. This is similar to my case, where there are those 3 wires, for the switch itself, the blue power light surrounding the switch, and a blue light on the top that blinks when the hard drive accesses. My wires are all red/white, though, and have the description printed on each.

Where to find manual for motherboard 143159 imperial Gv 20030812?


Good luck. Used to be you could get a mobo manual from e4allupgraders.

The Imperial board is made by TriGem
Started out as TriGem Sambo, is now TG Sambo

The Imperial models were Imperial G, Imperial GL, Imperial GV, and Imperial GLVE, if memory serves.

TriGem Imperial GV - 143159 -20030812

http://www.ebay.com/itm/gateway-emachine-mother-board-imperial-gv-20030812-/111025938736?pt=Motherboards&hash=item19d9a96130

Bad photo, but it does have the mouse Zoom In feature.

CMOS jumper and Clear BIOS Password jumper, down by the Front Panel header; is the same as used on the TriGem Imperial GLVE -129504,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph07540&lc=en&cc=us&product=83481

Scroll down to Motherboard Layout (Illustration), and Photo; then down to jumper info.

(By the way.........the BIOS chipset is removable, therefore replaceable)

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.

This is PANEL in the illustration. Bottom/Right corner. Uses the same Front Panel pinout, as your Imperial GV uses.

8 pins along in a row.
Starting on the LEFT side going towards the Right;
Pins 1, 2, 3, NO pin 4, 5, 6, 7, and 8.

A) Pin 1 is N/C. Not Connected
(May not even be there for all I know)

B) Pins 2 and 3 are for the Power On LED.
Pin 3 is for the Positive wire.
If the PWR LED is dim when the computer is on, switch the wires around.

C) There is NO Pin 4. At least that is what I make, looking at the Front Panel header pinout. Indicate Pin 1 is N/C, and Pin 4 is N/C.

D) Pins 5 and 6 are for the HarDDrive activity LED light.
Pin 5 is for the Positive ( + ) wire.
If the HDD LED is dim when the Harddrive is active, switch the wires around.

E) Pins 7 and 8 are for the Power On switch.

HOWEVER, since the motherboard photo on HP Support, and Ebay; is as clear as mud; suggest you do this,

Connect your Power On switch to Pins 7 and 8;
OR,
touch across them briefly with a small flat tip screwdriver.
(Power plugged in)

See if that is correct for the Power On switch. What will happen if it isn't? Nothing. Pressing the Power On button just won't turn the computer on; is all.

Turned the Power Supply (Computer) on?
Good. We can assume the rest of the pinout is correct also.
Want to make sure? Easy.

Take an LED bulb (Power On, or HDD), and touch it's two wires to the Power On LED pins, in the Front panel header.
Stays on? Yep. Power On LED pins.

Blinks? Whoops.
Those are the Harddrive activity LED pins.
Just that easy to check it. With using an LED, you won't harm anything even if the pinout is wrong.

Moving on.........

Using the HP Support page, for that TriGem Imperial GLVE motherboard, the Motherboard Layout is the same as the Imperial GV.
(So is photo, 'natch)

Referring to the layout, and photo;

A) Power cables:
Two
20-pin ATX main power cable, and 4-pin ATX +12 Volt power cable.

General example of a 20-pin ATX main power cable, and it's respective connector on the motherboard,

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

Note* Color of power cable connector does NOT matter.
Can be Whitish, Yellowish, Black, Sea Foam Blue, or Lactating Mammary Gland Pink. (Made the last two up)

Goes to the motherboard connector immediately above PCI slot 1.
Note the LOCK on the side of the power cable, and corresponding TAB on the motherboard connector.

General example of 4-pin ATX +12 Volt power cable, and connector on motherboard,

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

Power for the Processor
Looking at the motherboard illustration, look at the Northbridge chip; -> Intel 845GL in the middle.

ATX 12V to the left, is where the 4-pin ATX +12 Volt power cable plugs in.
See the aluminum finned Heatsink, sitting on the Northbridge chip?
The whitish/yellowish 4-socket hole square connector, to the Left.

Moving on............

See where it states Primary IDE to the bottom/right in the illustration? Blue IDE connector?
That is where the Harddrive plugs in.

This is a general example of the connector,

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

Note the Locating Lug on the top/middle. This particular style uses two ribs. Some are just a solid block.

The reason I brought it up, is if there is NO Locating Lug on the connector; let me know in a Comment.
I'll tell you how to use the faint Red stripe, on the side of the flat cable; in order to plug it in correctly.

The optical drive (CD/DVD drive) plugs into Secondary IDE.
You can see where a Floppy Drive plugs in.

Above the Processor (CPU) socket to the Right, is where a computer case fan plugs in. PS_FAN.
To the upper Left, is where the Processor fan plugs in.
CPU_FAN

To the left of the ATX Power Connector, (20-pin ATX main power cable; motherboard connector), is the connector for the small audio cable; coming from the optical drive. (CD/DVD drive)

Optical Drive In.

Right next to the round CMOS battery, is the Front Panel USB header.
-> TWO USB ports connect to this header.
(USB)

A 4-pin Peripheral power cable is used for the Harddrive, and Optical Drive.
Misnomered as 'Molex' power cable,

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

Note the rounded corners. When plugging the power cable in, these rounded corners always go UP.

[Molex was the first maker of the power cable connector.
The name stuck.
Kind of like calling an adjustable open-end wrench a 'Crescent wrench' ]

The motherboard chipset is an Intel 845GV.
This is what Processors (CPU), and Ram Memory are supported,

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Pentium_4_chipsets

Single-Core processors.
Use a Socket 478 processor socket.
Intel Pentium 4, Celeron, or Celeron D.
(Celeron D is NOT a dual core processor)

400 to 533MegaHertz Front Side Bus processor support.
(400/533MHz FSB)

DDR Sdram ram memory that is either 266MegaHertz, or 333MHz.
(PC2100 and PC2700, respectively)

2GB's of it.
1GB for EACH ram memory slot.

After flash BIOS DMI Update fails ?


If you are able to boot into Windows, don't try it again. If you are not able to, try to reflash it. If that fails, contact the tech support for the bios and see if they have any suggestions, sadly I doubt they will. You may end up having to replace the mother board.

Try replace the Memory module (DDR2 RAM) with new ones.That's should fix it!!

If still won't come out, replace the power supply unit.
