Comment:

Hello, I've acquired some old computer parts from a friend of mine. He had no manuals or anything for the stuff. I got a hold on 2 motherboards, 2 processors (P2 & P3), and some various other computer hardware. I'm trying to install one of the motherboards into an old ATX case I have. The case 11 years old, and was the housing of an OEM Gateway 2000 Pentium 1 computer. I removed the Pentium 1 motherboard from the case and installed one of the motherboards that I got. The one I installed is an Intel E139761. Everything fit perfectly inside the case. But I'm having a time with the front panel connectors. I've seen several diagrams on the internet of supposedly the same board, but the diagrams are all different, and I have no idea on which one is correct. I don't want to fry any of the LEDs or buttons. Some diagrams call for a split (one-pin) connector, one pin here, but another one over there; the problem is that the case connectors are all 2 pin or more. The Power LED connector is 3 pins, but the one in the middle is white (blank). The markings on the board aren't clear at all, and I don't even know the correct polarity of either the case connectors, or the connectors on the MB. I need a manual or something for the exact board that I have. If someone could shed some light on this I'd really appreciate it. The chipset is Intel AGPset 82443BX

I did some checking and I believe that board was used in some Dell computers. Possibly check on Dell site.

Thanks for that. I read that it was used in some Dell Machines too, but just now I found out it was used in some Gateway machines also. I stumbled across a motherboard on the Gateway Support website with a model number the exact same as mine. I still can't understand even the Gateway page. I've built and rebuilt several machines, but this one I can't figure out.

Ok I've looked at the info on the Gateway site, and I understand it a lot better now. But one thing that the site does not specify is the correct polarity of the connectors. There are no polarity markings on the motherboard either. How do I know that I'm plugging them in the right way? If I plug the PC in and turn it on with the front panel connectors wrong, I've heard that you can damage the LEDs or buttons in the front. Is this true? Thanks!

Don't know about burning out LEDs but the switches are just momentary contacts complete circuits. Doesn't matter which way. Your bigger issue could be the 20wire power connector. I understand that many OEM vendors use propietory PSUs and MBoards. While I don't think that is the case here it could be a possibility.

Thanks for that, I checked to be sure about using the propietory PSU and Gateway's site said ATX compatible.

After browsing the internet, I saw that the polarity does not matter and if the polarity is wrong with the LED, just switch it around.

With all of that in mind I went ahead and tried to boot with the basics 1 stick of RAM, video card and CPU. The computer does not start when pushing the button. The same thing happened when I tested a new motherboard in the same old case. Could there be something with the case wires preventing it from turning on? The same connectors turned the Pentium 1 on fine when the button is pushed. Thanks again.

Alright an update. I just tried the other motherboard that I got, a Superpower Computer SP-P2BXA motherboard. I tested this board outside the case by shorting the power button pins. This triggered the power supply unit to start running, but none of the CPU fans would work which prompted me to not have it plugged in for more than a second or two. I had nothing but the CPU and a stick of RAM, no video card at all. Why won't the CPU fans run? When I say fans in the plural I mean I have 2 fans that I tried. I tried them out in another computer and they work fine. I'm going to get this other board and test it out of the case too. Thanks for the replies and help.

Ok I tried the first board out of the case, nothing at all. I didn't install the video card. Does the video card need to be installed for the fans to run?

I can't install the second board in the case because there's a standoff in the way that I can't remove. It's a totally round standoff. While the regular metal standoffs are round, the sides of the standoff I can't move is smooth, while the regular ones aren't. I've taken pliers to it and tried with my fingers and it won't budge. It's a standoff that the manufacturer of the computer used. Is it not coming off because the case is from a branded PC (Gateway 2000)?

One more question: I've heard that a 145W power supply is cutting a P3 450MHz a little close, but should do fine. Is this true? The power supply was also used in the P1 system. According to the specification sticker on the power supply, the 3.3V rail only has a maximum of 100W. This to me sounds the power supply might be underwattage. What do you think? I don't have another PSU to try. I was only going to use my hard drive, CD burner, graphics card (old AGP 1 card) and wireless network card. That's it. I would like to hear your opinions on it. Thanks.

You must realize any or all this hardware could be DOA? edit

Forgot to comment on the PSU wattage. If memory serves me correctly my first 486 had a 250Watt PSU. 145Watts is usually relegated to micro cases. If you suspect the PSU then try booting without any drives connected. That should mitigate some of the short capacity.

Thanks very much for the reply. I don't want to damage that power supply because if none of this stuff works, I want to use it again with that P1 system. But would it be safe to connect the AGP 1x card, memory and CPU only to the motherboard and try booting with the 145W PSU? I've heard that even AGP 1x cards can consume 20 watts or more alone, and the sticker on the supply says that the 5V rail and the 3.3V rail are both 100 volts max.

Another question: The CPU fans don't come on, but they do when I connect them to a Fan header in another board I've had awhile. Do some P2 and P3 BIOSes have a fan control system that turns the fan on when it gets above a certain temp? Thanks.

You mean 100 watts max. I don't think the CPU draws that much. I'm thinking 35W. I could be totally wrong on the wattage but that number sticks in my head.

I'm thinking the CPU fan should be running anytime the computer is on.

The standoff you mentioned awile back that won't come out could be shorting out the board. Is that standoff in line with a screw hole? If not I would insulate it. Don't use anything thick, couple of layers of electrical tape.

Thanks I never thought about insulation! I could try that. On the first board, the standoff was under a screw hole, the second board, there's not a screw hole there. I was wondering how I was going to get that board in there.

In regard to the stuff being DOA, the friend that gave me this stuff said that it worked when he took it out of the case. For that reason I don't know why it won't work.

I'm going to try to insulate that standoff, then I'm going to try to install that 2nd board in the case with nothing but the CPU, 1 stick of RAM, and video card. I'll only have it on for a few seconds to see if I get a video signal. P2s don't get hot real quick do they?

Thanks for the help!!!!!

Thanks for correcting me on 100 volts, I meant watts.

I wouldn't run the CPU without cooling for long and not without a heatsink at all.

Are there a bunch of jumpers on the MBoard. You may need to set the CPU frequency, voltage, etc.

Ok I got that standoff covered with scotch tape, got the second motherboard installed in the case and everything connected. The markings on the board are better detailed than the first board. I push the button and everything comes on except the CPU fan, and there's no monitor signal. I might try to install the P3 next and see if there are any differences.

Tried the P3, no difference. The CMOS battery was dead so I put in a good one, same thing. I tried different RAM, still nothing. Oh well I guess both boards are bad. Either that or the there's a lack of wattage with the power supply. I can't understand how that could be the case since all I had plugged in was the motherboard, CPU, RAM, and graphics card.

Thanks for the help OtheHill, you've been a very big help.

Are there dipswitches or jumpers in a row on the board? If you have/had the voltage settings wrong for the processor you could fry it in a moment. If the multiplier is wrong it may not jurt the CPU, just won't boot. Removing the battery should clear the CMOS but once you have a boot failure you may need to reclear. Hard to work with old stuff when going blind. Did the MBoards have a processor mounted on them when you got them?

I may be way off base on the way the Intel chip boards you are dealing with work. The last time I built an Intel setup was a Pentium 133. Therefore I don't know when soft settings came to the P line.

Well there is a set of pins called JFSB. There isn't a jumper on it. I read online the following:

No Jumper: AUTO
1-2: 66MHz FSB
2-3: 100MHz FSB

There is some text on the motherboard that says about the same thing as the above.

There's also another set of pins that according to the internet is supposed to set something called "BIOS Voltage". According to the internet, this is what I found:

1-2: BIOS 5V
2-3: BIOS 12V

There isn't a jumper on it though. Could this mean anything?

None of the processors were mounted to the board when I got them. I've tried to reclear the CMOS even after it wouldn't boot.

There aren't that many set of pins on the board, but there is another set of pins with about 2 or 3 jumpers on them, but there isn't a name or anything under it that I can look it up and see what it's for.

If you have anymore ideas, please send them on.

With the board I've been trying (second board I got) I've connected the graphics card, monitor, keyboard, CPU and RAM. The first board I never did hook the graphics card to it because it would always act like it was unplugged when I'd try and turn it on. Would the absence of a graphics card cause it to act this way?

I talked to my friend, and he's going to send me a 300W power supply that he said he used with one of the boards. We'll have to try that and see if it makes any difference. OtheHill, you've been great with your help and I can't tell you how grateful I am for it!

I never owned a Intel slot processor but did have a few AMD slotA boards. The processor came with some plastic brackets that held the processor from sagging. The problem might be corrosion on the contacts. They should be shiny. plug it in and out a few times. You probably can jury rig something if it is really sagging. However that doesn't sound like a workable solution. Maybe wire ties around the HSink to a higher place on the board.

Thanks for that quick reply, I've not been able to respond till now. I've been trying to get the same motherboard to POST. The fans run, but it doesn't POST. I've tried 2 graphics cards, I've tried to boot with RAM and without. I would think that I would get a beep from the internal speaker when I turn it on with no RAM, but I don't. I've also hooked an external speaker from a case to it, and still no beeps of any sort. I've read here on computing that no beeps possibly means a bad motherboard. If I could get it to POST, I could figure a good way to secure that CPU in place. My friend never did send me that power supply, I think he changed his mind. I'm still using the 145W. A local computer store in town has some used power supplies that they said they would let me have for anywhere between $5 and $10 each.

Guess what!!! I got that first motherboard to POST!!!!!!! I'm so happy I could yell. I've gotten it to work on that 145W. I probably should upgrade the power supply.

The problem was the box I was testing it on. It was covered in packaging tape (which I didn't think was conductive). I had the board on top of it. Nothing but the fans came on until I moved it to the top of another box of a motherboard I had. Now it is posting, the fans are running, and I can use my keyboard to access the BIOS. This has been a major breakthrough. Now let's hope it keeps working and that I can get that CPU secured and also that I can set it up to use as an "upgrade" from the Pentium 1 I've been using that only has 64MB of RAM.

When you reenter the BIOS is the date correct each time? That would indicate the battery is holding the settings. There should be a setting to choose onboard or PCI graphics as the first display. Choose onboard. There should be a setting to choose the amount of shared RAM too.

Ok I have good news again, but I hope it stays this way. The P3 that I had in there was what was causing the PC to not POST, and also what was causing the video signal, but nothing on the monitor. Last night I was desperate and just for the fun, I thought "What would I lose" and downloaded the latest Gateway BIOS for this board and installed it using Gateway's BIOS Recovery method. It took almost 20 minutes, but after awhile the motherboard beeped and the floppy light went off. I shut the computer down, unplugged it and replaced the BIOS configuration jumper. I felt of the heatsink and it was cold as if no juice had not gone through it for the past 20 minutes. I started her back up. I got the same symptoms as before, a video signal, but no POST. This morning I was reading on another forum about someone who had the same exact problems as I did and the person had a stone cold heatsink like me. An expert suggested a bad CPU. I took that suggestion to heart and installed the P2 my friend sent. Voila, it's working again, but only God knows how long. Thanks OtheHill for your help and for sticking to this thread. Most people would give up by now, especially for such an old system.

Hey OtheHill, today I did testing on this system, adding each component in and turning the system on each time. As far as I could tell, everything seems fine so far. I just packed it with 384MB of RAM, and installed Windows XP. It's blazing fast and snappy for such an old system. I want to tweak it even more by turning off unneeded settings to make it faster. In performance, this thing beats that P1 by a long shot. OtheHill, you've been great and like I've said, thank you for all you've done to help me. I'll be using and testing this computer the next few days so I don't know if I'll need you again or not.

Thank you. BTW, do you know what might make a CPU to make a little noise when I scroll a window or maximize a window? I'm getting that with this system. Everything seems fine but that. I've been reading again online and people act like it's no big deal. The noise sounds a little like chirping, but it's faint. I know it's from the CPU instead of the PSU because I put my ear to it and scrolled a window and that was where it was coming from. What do you think?

Not really, I just wanted to know in case the noise was some sort of problem fixing to happen. I'm sorry for asking so many questions, this thread sure did get off topic. But I've got 1 more question. I didn't figure out the front panel connectors until now, and got just the hard disk activity light connected. The LED is noticeably brighter than it was with the P1 system. Is this a concern?

I don't think the polarity matters but you could try reversing the two wires. That could also be a function of the voltage sent be the MBoard, which could be different in each case. I guess I can't give you a good answer.
