Intel Board with problems.

[Lance Thornton]

Hi all,

I have an Intel board in front of me. Intel Type D845EPI/D845GVSR It does not boot. I have a known good: power supply, cpu and memory. It does have a led to indicate power on, but the pci post card does not have any voltage to it, nor does the board boot to even the slightest bit. All caps are fine, but of unknown origin. Markings are KZE 1200 microfarad @ 16 volt for the large ones and KZV 820 microfarad @ 4volt for the 8mm caps near the cpu rack. Any thoughts or ideas would be appreciated. Thanks for looking.

United Chemi-con makes a KZE series. Nippon Chemi-con has a KZV series.

Thanks, now if I could only figure out the main problem!

Re: Intel Board with problems.

The point was, they aren't crap caps that just look good. What is the board sitting on? We quite often see people trying to test a board while it is sitting on an anti-static bag. These are conductive, and can short pins together, causing random errors. Better to test the board properly mounted in a case, or sitting on a couple blocks of wood. Can you measure the voltages on the back side of the ATX connector, to verify that everything is getting on to the board? If all is well, there may be a problem with one or more VRMs (CPU or memory would be likely candidates). See the FAQ on testing VRMs.

What's the diff. between Nippon and United ChemiCon?

Re: Intel Board with problems.

The board was sitting on my workbench in the shop. At no time did I have it on an anti-static bag. I have not had the opportunity to check voltages at various points on the board. When I do, I'll report back. Thanks again.

Re: Intel Board with problems.

what is the history of the board? was it from an emachines?

psu died and nuked the power section?

[Lance Thornton]

Re: Intel Board with problems.

The history of the board is unknown to me. It did come out of an E-machine, but other than that, I'm clueless. I haven't had any time to work on it, and I don't expect that I will soon. I will create a new thread, or append this one when I have more information. Thanks again for the help and thoughts.

Re: Intel Board with problems.

What kind of port 80 card do you have? Does it have indicators for PCI_REset, +3.3, +5, +12, etc, with a pair of 7 segment LED displays? Or does it have less than that?? Having no +3.3V and +5V to the slot would be quite unusual, i would think it would be a PSU issue then, as the traces that provide power to the slots are quite big. I've brought a Gigabyte 760MPX board back to life, but it had power to the PCI slots at least.

Re: Intel Board with problems.

gg1978; where can such a Port80H device be bought? I've only seen the ones included with Epox mainboards...

But I've been looking for a good PCI Port80h device for a long time...

The meaning is same, they are same company.

Re: Intel Board with problems.

I've made ISA POST card some time ago by adding some logic chips to 1986 serial port card. But newer boards don't have ISA anymore so I was searching for a PCI POST card - found this:
http://www.eztest.com.tw/products/post.htm
http://www.costronic.com.tw/
But nothing that was available locally here. Then I found MSI TL46 Service Kit and bought that. It's PCI post card with network card and two BIOS sockets (DIP32 and PLCC32 for FWH chips) - you can put a preprogrammed chip there, flip a DIP switch on the card and boot from it. It's REALLY good if you have a board with soldered flash ROM chip and the BIOS was corrupted. Manual says that it works only on MSI boards but it works on many other boards too (not all). The kit also came with some I/O shields, USB and firewire brackets but I have no use for that.

Re: Intel Board with problems.

I bought my port 80 card from Best Buy i believe. It's made by Soyo. Geeks.com used to have them, although i just checked there, and they don't have them anymore.

Re: Intel Board with problems.

Bought rev 3.2 of this card off eBay for less than 5$, what a deal!

Where can find a SOYO PCI debug card? It is so diffcult to find it. I have found it for a lont time. I am using EPOX debug card now.

Re: Intel Board with problems.

Found two on e-bay..

http://cgi.ebay.com/Brand-New-SOYO-T...QQcmdZViewItem
and
http://cgi.ebay.com/NEW-Soyo-Compute...QQcmdZViewItem

But what is so great about this Soyo post card then?

Re: Intel Board with problems.

I have one of those, it always says FF even in a working computer.

Re: Intel Board with problems.

Some boards don't send the port 80 codes to the 32bit/33mhz PCI bus.

My Gigabyte 760MPX motherboard doesn't.. I assume it sends the codes to the 64bit/66Mhz PCI bus.

I've also got a Gigabyte Socket 370 board that only sends port 80 codes to the ISA bus, luckily it actually has the ISA slot populated.


You can still see if the board is attempting to boot, even if the port 80 codes aren't available. on the Soyo card, the PCI_RESET is on when you first turn on the system, if it turns off, the system is attempting to POST at least.

Re: Intel Board with problems.

Also there are some BIOSes (maybe some Compaq?) that don't use port 80h but something other.

Re: Intel Board with problems.

Hi folks, this is my first post.
Anyway, I have the same board with the exact same symptoms.
My board does not boot. The PS is good and produces the power light (green) on the board.
I just wanted say that mine has at least 6 blown capacitors immediately next to the cpu. Electrolyte is leaking from the top of one and all have blown caps.
Although I have an electronics degree (1988), it has been a long time since I have practiced it and am going to send mine to Badcaps and have all of them replaced.
I just wanted to "second" the problems with this board.
