Question about EliteGroup N2U400-A Motherboard
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.
