Drivers for imperial glve 20021218 - E-Machines EMA IMPERIAL GV (845GV) TG3 eMachines (145119) Motherboard

Yes as long as it is the same case stile and 400 mhz.
Base processor Intel Celeron 2.7 GHz

• 400 MHz Front side bus
• Socket mPGA478
  Note.... Make sure you use PC2700 memory PC2100 will give you error messages
  

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

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.

TriGem (Company) Imperial GLVE (Model)

http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&dlc=en&docname=bph07813&lc=en#N779

http://www.trigem.co.kr/tgservice/econsult/faqProduct04.asp?cls=0&Page=&ID=4237&C1=1&C2=68&C3=359&C_N=IMPERIAL-GLVE

Hmmm, I'm at a stalemate.

Looking at the specs for the motherboard chipset;
The Northbridge and Southbridge chip,

Intel 845GV

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

Supports CPU's with a 400MegaHertz Front Side Bus, or a
533MHz FSB.

Naturally I can't get a clear picture of those jumpers, but they look to be 3-pin.

If we are to assume that the jumper pins set the CPU FSB support, from 400MHz to 533MHz, then the jumper cap is moved from either

Pins 1 and 2, to Pins 2 and 3; on J2 jumper;
Or Pins 2 and 3, to Pins 1 and 2.

I know !O_O!
Sort of a guessing game, as to where the jumper cap goes to what pins, for 400MHz FSB support, or 533MHz FSB support.

Do you have any idea of what the FSB is for the old CPU (Processor), that was in the motherboard? (Or is)

Let's say 400MHz.
You now know if the CPU you are wanting to use, needs 533MHz Front Side Bus support, you need to move the jumper cap to the opposite pins.

What happens if it's wrong? Nothing. processor just won't work.
Change the jumper cap back.

(NOT plugged into power when you do. Also FOLLOW Anti-Static Precautions)

Yes. I'm 'out there on a limb'
I am assuming after looking at the TriGem support page, for the Imperial GLVE motherboard, that the J2 jumper is used to change the FSB support for the Processor.

It MAY be that J2 has Nothing to do with CPU Support.
It may be that there is no jumper for changing CPU FSB support.

(Cleared that right up, huh? Geez!)

For additional questions please post in a Comment.

[J1 = FDD. Floppy Disk Drive
J2 = CPU FSB jumper
J3 = CMOS Setup
J4 = CMOS,

IMHO ]

should be this one TriGem Imperial-GLVE

pity it does not have agp. any m-atx or uATX whatever you like to call it should fit.

Quote: Glendale/Imperial TriGem Imperial-GLVE (31891.HPD.0000.D.0310140908) used in HP Pavilion models:-

503a, 503n, 503w, 513a, 513c, 513n, 513w, 522 cfg-PC, 522a, 523a, 532w, 533a, 533c, 533w (serno KR or CH), 542x, 563w, 712a, 742c, 752 cfg-PC, 752c, 752n, a200y, a400y, a210n, a200n, a376x, a347x, a342n, a340a, a335w, a320a, a317x, a310n, a305w, a302x, a300y

NOTE: It has been documented for the Echo GL Asus P4G533-LA/P4G533-GL (10/16/2003-I845G/ICH4/IT8708-P4G533LA )that it was also used for the pavilion a305w and in the following models:-

354n (US/CAN), 525w, 533w (serno MX IT8708F), a210n, a206x, a345w, a336n, a335w, a328d, a320d, a318d, a316n, a312d, a307i, a305wm, a305w, a305i, a300n, a424x, a422n, a412n

I would suggest this generic Power On switch,

1) http://www.directron.com/atxswitch.html,

and the Red, and Black twisted pair of wires go to the Power On switch.

Your statement of ,"....don't know which of the colored pairs of wires go.....", leads me to believe you may have all of the Front Panel wires disconnected.

How about information as to where ALL the Front Panel wires go?
(Provided I have correctly interpreted your statement)

Back in the time that the eMachines T2542 was made, TriGem was the motherboard manufacturer.

The Model Name of the motherboard is Imperial, and the Model Number of the motherboard, could have been one of four variations offered.

Model Name: Imperial
Model numbers could be G, GL, GV, or GLVE
(Imperial G, Imperial GL, Imperial GV, or Imperial GLVE)

ALL four variations used the same Front Panel header.
(The connector on the motherboard the Front Panel wires connect to, is named the Front Panel header)

I would like you to view this page,

http://www.e4allupgraders.info/dir1/ecase/support/front_panel_header_support.shtml

Scroll down to the heading -
Trigem Imperial Front Panel Header Pinout.

A) Pins 1, 2, and 3 are for the Power On LED light.

B) Pins 5 and 6 are for the HarDDrive activity LED light.
(Pin 4 is not used. NC. No Connection)

C) Pins 7 and 8 are for the Power On switch

D) I wouldn't connect any wires to Pins 9 and 10, nor Pins 11 and 12

E) Pins 14 and 15 are for the Reset switch. (The button you press to restart your computer.
If the T2542 doesn't have a Reset switch, don't worry about it. There are many other ways to restart your computer)

F) Pins 17 18, and 20 are for an internal speaker.
This speaker is used for BIOS Beep Codes.

In the chart to the right, you will see GRD used many times.
GRD stands for Ground.
ANY Black wire in the twisted pair of wires, is a Ground wire.

Most of the eMachines I have worked on, use a Red, and Black pair of twisted wires for the Power On switch.
I could be mistaken on the T2542.

Best method, is to follow the color code of the wires that come from Pins 7 and 8, and be sure.

Save all your important files , then reformat your operating system

Hi there.
Get a strong flashlight and a magnifying glass (if you have one). On the motherboard look for the front panel, it should be marked PWR and coloured green, also the plug that connects to it should be marked PWR_SW. On some boards there are no colours but the markings are the same, so a good close look.
Have a look at these pictures for an idea >>>>>>




Please post back with the results and any more advice if needed.

Good luck and thanks for choosing FixYa!!

HP uses proprietary boards so a regular ATX board wouldn't work. Here is a link to a store that carries the replacement you need but if you have time you may be able to find it cheaper elsewhere. http://product.pelltechnology.com/HP_Pavilion_a305w_Desktop_PC_Motherboard_Replacement.asp
Hope this helps & please remember to rate my answer. Thanks.

Normally on the board there is silk printing to state what connection goes where. Also on the black connector i.e. power LED there is a small arrow that goes to pin 1 of the POWER LED pins.

Hope that was any help thanks J
