Controller on Mobo Moderator: The Mod Squad Post a reply 4 posts • Page 1 of 1 Reply with quote PCI/PnP Error! Resource Conflict- Network Controller on Mobo by thinkcentre_a53 » Fri Feb 22, 2008 1:23 am Hi Everyone, I am new to the issues surrounding BIOS hence I have landed myself in a bit of a hot water. I will appreciate if someone could help: I have a Lenovo ThinkCentre A53 with WinXP. It has Phoenix Bios. I installed a Dual-View NVidia VGA on the PCIx16 slot. As a consequence, at bootup, I saw a "1806: PCI/PnP Error! Resource Conflict - PCI Network Controller Bus:00, Device:0C, Function:00". I was however able to carry onto the WinXP but once inside the windows, I get a message asking for a driver to install the ethernet controller. I downloaded the network driver from Lenovo but windows didn't recognise the driver. So, I reverted back to the factory-shipped state of the machine by taking the expansion cards and reflashing the BIOS. However, the beeping and error message still haven't disappeared. I am thinking aloud here but do I need to reset some "registers" somewhere for the motherboard to forget something? Is it at all possible to fix the problem? Thanks a lot in advance for all the comments and suggestions !! thinkcentre_a53 Pilgrim Posts: 2Joined: Fri Feb 22, 2008 1:09 am Top Reply with quote by evasive » Fri Feb 22, 2008 4:21 am Inside the bios there should be a setting similar to "reset to factory defaults". If not, there's a clear CMOS jumper. If not, it's possible to unplug the machine from the mains and remove the CMOS battery (a coin cell battery) for 10 minutes or something whcih will have the same effect. You did check with Lenovo if that nVidia card is at all compatible with the A53? We hate rut, but we fear change. ******************************** System error, strike any user to continue... evasive Mobo-fu Master Posts: 37310Joined: Sun May 06, 2001 12:01 amLocation: Netherlands Website Top Reply with quote by thinkcentre_a53 » Fri Feb 22, 2008 6:56 am Hiya Thanks a lot for the reply! I did actually do everything that you suggested but sadly without any success. 1. I had reset the machine to factory defaults. By the way, this only brings the OS stuff back to factory-shipped state. 2. I unplugged the power cable. I switched the CMOS jumper to clear CMOS setting. The machine kept beeping when I restarted. I turned it off after about 15-20 secs. I then unplugged everything and put the CMOS jumper back into

I got this PC from people selling them as an office equipment clearance. When I powered it ON, it boots straight into WindowXp without problem or any error message. However, there is no network available. No network adapter appears in PC hardware manager list also. I http://www.motherboards.org/forums/viewtopic.php?t=104907 then power down and enter BIOS screen, noting that the on-board ethernet controller option has been disabled. So I thought it would be a piece of cake just to turn it back on and save back the new setting to CMOS. I'm home and dry. On power up again, POST immediately reports an error message 1806 on PCI/PnP resources conflict. It clearly http://forum.allaboutcircuits.com/threads/ethernet-resource-conflict-ibm-thinkcentre.47389/ states that it is caused by the motherboard ethernet controller. Thinking that it could be a driver problem I then proceed to boot into XP and note the yellow exclamation mark on the network adaptor saying software for the device has not been installed. Fine I go ahead and installed the correct driver. Installation completed successfully and OS requested a system reset. After a reboot, still the same POST resource conflict error message and inside device manager the yellow exclamation mark on the network adapter is still showing. However, this time the problem is that Window cannot start the device(probably because of the hardware resource conflict). I then went back into BIOS and disable the ethernet controller and verified again the resource conflict message has disappeared. I powered down the PC again and installed a separate PCI network card. To my surprise, the POST immediately reports that the new PCI network card I have just inserted also caused resource conflict. Finally inside BIOS I disable the sound card and all the COM and parallel port to free up some resources but th
