Question about EliteGroup N2U400-A Motherboard

1 Answer

ECS N2400-A (V1.0), Power LED = Not Lit (!Lit) , IDE LED = Lit

1] Installed board, without scratches (visual inspection can confirm this)
2] Tried to start with PCI Video Adapter and Memory PC3200U: Samsung, M268L6423HUN-CCC; unable to confirm if memory is unbuffered (still)
-IDE Lite, Power did not
a] Tried AGP adapter, it does not have the notch at the end which goes back then up (3.0V and still 8x, a miracle in modern engineering)
[I saw those a while back and looked like the dickens for one that would work in my computer at the time (a NOT 1.5V), hunh?
-IDE Lite, Power did not [hoped that the power supply latched to block power to certain critial components on the board, when the
-above memory was used [still don't know if it's unbuffered] with the PCI Adapter, therefore I haven't ruined the board
*Should I try AGP Adapter, I will be properly equipped, with one (1) 1.5V AGP Adapter, with the back then up notch.
b] Slotted the above memory in DIMM 1, then DIMM 3 and left it there, and ordered unbuffered memory.
3] Unbuffered memory arrived. PC2700/512MB, AMPO 35144588-PB / P218656
4] Tried to start with PCI Video Adapter and memory in DIMM 3, DIMM 2, and then DIMM 1, results,
-IDE Lite, Power did not
5] Installed old board.
-IDE Lite, Power Lite, Power Supply not at fault
6] Confirmed Documentation, what's is Pin 1, at JP1. Pins 1 & 2, normal running, Pins 2 & 3, CMOS Reset. Pin 1 is the pin furthest from the Battery. Voltage 1 to 2, at Battery to Half (looked at more that one board), Voltage Positive, Voltage 2 to 3, 200 to 700mV, Voltage Negative.
7] Still have one more question, Bios. What do you do if when you're done updating/replacing Bios, the thing don't Boot. My other boards have a Bios Socket, you simply remove the Bios EPROM and replace it with one written by someone like 'BiosWorld'. This unit has a BIOS EPROM soldered to the board, there is no socket. There must be a way of programming the Bios, even when the Bios is crashed. Thru the Card Reader, or LAN... something. Heck, I was programming EEPROM back in 1978 for a microprocessor product I was writing the software for, using a Prompt 48, so programming EPROM's doesn't scare me. I just need documentation that describes was must be done to do it. The factory has to program those things when they make them, my guess is that they do not program the Bios EPROM until after the EPROM has been top soldered to the board.

This looks like a good quality board, it looks clean. I'm sure it will work well, as expected, once I stop installing unknown
components (memory), and/or components specifically called not to use (3.0V AGP).

The most common way of programming bios that i know of now is through a fire wire or USB port you can buy the program that sets you up to do this at any major computer store. i use a server with the program and set all the machines i build with all the bios info from start up - to user executes application. and i establish a custom POST set up . you are right its nothing to be afriad of you just need the tools.

Power supply diagram for ht 2000 motherboard

1) Uses one 24-pin ATX main power cable.

Motherboard installed in computer case, the motherboard connector for the 24-pin ATX main power cable; is to the Right of the Blue IDE (PATA) connector.
(Right side of motherboard)

General example. Note that color does NOT matter of connector,

2) Uses one 4-pin ATX +12 Volt power cable,

Motherboard installed in computer case, the whitish square 4-socket hole connector, to the Bottom/Left corner of the Processor socket; is the 4-pin ATX +12 Volt power cable's motherboard connector.

General example. Note color does NOT matter of connector,

THAT, would be considered a Power Supply diagram of the motherboard.

They are the only two power cables that plug into the motherboard.

The front of your desktop 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.

Power On switch, Power On LED, (Light Emitting Diode), Harddrive activity LED, and a Reset switch IF used.

Hello the manual can be downloaded here:



Hard Drive Activity LED
Connecting pins 1 and 3 to a front panel mounted LED provides visual indication that
data is being read from or written to the hard drive. For the LED to function properly,
an IDE drive should be connected to the onboard IDE interface. The LED will also
show activity for devices connected to the SCSI (hard drive activity LED) connector.
Power/Sleep/Message waiting LED
Connecting pins 2 and 4 to a single or dual-color, front panel mounted LED provides
power on/off, sleep, and message waiting indication.
Reset Switch
Supporting the reset function requires connecting pin 5 and 7 to a momentarycontact
switch that is normally open. When the switch is closed, the board resets and
runs POST.
Power Switch
Supporting the power on/off function requires connecting pins 6 and 8 to a momentary-
contact switch that is normally open. The switch should maintain contact for at
least 50 ms to signal the power supply to switch on or off. The time requirement is
due to internal de-bounce circuitry. After receiving a power on/off signal, at least two
seconds elapses before the power supply recognizes another on/off signal

Good luck

Hello sir hi, try cleaning the memory modules of your PC. also review your power supply connection. and check the following sequence of events. 1. power on the PC. 2. fan should be blowing. 3. keyboard light, scroll, numlock and capslock lit and then goes off. (if this does not lit, you have a mother board problem) 4. you should hear a beep. (1 beep is normal, 1 long and 2or3 short beeps, means display problem) 5. the numlock is lit. (no light means problem on the motherboard) 6. the display monitor will now display the CMOS. 7. your drive should turn/spin or HD led lights.
Im not so sure if the motherboard develops errors due to being not used for a long time, and may now have slimes and battery leaks that may be present on the board, a visual inspection is needed here, remove your motherboard out of the case and inspect all area for chemical creeps.

Please connect jPw1 to 4 Pin 12v, this supplies power to CPU. Than enter Bios & find Boot settings. Set the cdrom as boot 1 & hd as boot 2. Check the jumper on the cdrom, as it is the only device on secondary IDE controller it should be set as a master.
It is better to install a fresh copy of windows with a new motherboard. Put your windows CD in the cdrom & the system will boot to it. And your on your way. You can install the drivers for the board after windows has been installed.
Plaease vote..
