I bought a PCI card USB 2.0 NEC chipset based and disabled COM1, COM 2 and LPT1 in BIOS to free IRQ for USB and therefore IRQ 10 is shared between audio and USB causing trouble while IRQ 02, 03, 04 are always not allocated (not assigned). Sometimes, the floppy disk player runs, at any time. If you could help me, you should be thanked a lot ! From lisearia. (I own a 7ZXE MOTHERBOARD with VIA KT133A. The BIOS is 7ZXE.FB downloaded from Gigabyte.com (for American Megatrend) on Windows XP SP3

COM1 and COM2 refer to a computer's communications, or serial, ports. COM1 ports are often used on older PCs to connect network devices, digital cameras and mice. Faulty drivers software that enables the hardware to communicate with the operating system or incorrect hardware configuration can influence COM1 behavior. In rare cases, the expansion card that adds the serial ports to the PC can fail, rendering both COM1 and COM2 ports useless. To repair a COM1 port, you must determine what is preventing the port from working before attempting a solution.

Click "Start." Go to "Control Panel" and then click "Hardware & Sound." Select "Device Manager" from the submenu. Expand "Ports (COM & LPT)." Double-click "COM1." Review Device Status on the General tab to check for problems with the software driver. If the message "The Device Is Working Properly" appears, click "OK" to close the window; otherwise, look up the error message on Microsoft Support. Follow the directions in the Knowledge Base to correct the issue. Press "Alt" and "V" to open View. Scroll to "Resources by Type." Press "Enter." Double-click "Interrupt Request (IRQ)" to see a list of devices. Double-click "Communications Port (COM1)." Check the term to the left of COM1 to see if the card uses an ISA or PCI interface. If the card uses a PCI interface, it can use the same IRQ as another PCI device without producing a hardware conflict. If the device is ISA, it needs its own IRQ. Go to the "Resources" tab. If "No Conflicts" appears in the Conflicting Device List, close the window; otherwise, uncheck "Use Automatic Settings." Click the drop-down menu and select each configuration until the port no longer interferes with another device. If conflicts occur with each configuration, double-click "IRQ"; you may need to try different configurations before Windows gives you permission to edit the interrupt request. Click the up or down arrow to change the IRQ until the message "No Devices Are Conflicting" appears in the Conflict Information field. Click "OK" to close each window. Click "Yes" when prompted. Connect a device to the COM1 port to test the port. If the device doesn't respond, shut down the computer and then unplug the power cable. Disconnect all devices from the back of the PC. Remove the case cover and touch the computer's chassis. Set the computer on its side so that the PCI and ISA cards sit at a 90-degree angle to the floor. Find the serial ports on the back of the PC. Look on the opposite side of the case to find the associated card. Shine a flashlight onto the card and make sure that the copper contacts are not visible. If you can see the contacts, reseat the card in its slot so that it's fully installed to the motherboard. Reassemble the case and boot into Windows to test the COM1 port. If the port still fails to work, you may need to replace the serial port card.

Your N9600GT provides two HDMI out puts for dual display.
Even though you are currently only using one HDMI. Switch your monitor cable to the other HDMI out put. See if you now have display.
Also while in the bios allow, Page 2-27 in manual, Allocate IRQ to PCI set to [Yes]. Page 2-24, Internal Graphics Mode Select, [Disable]

Luck!

During the initial boot sequence (as soon as you turn your PC on), try pressing <DEL> button (or F2 or F10 - you will see info on the bottom of the screen stating something like "Press _____ (del, F2, F10) to go to Setup..."

This will take you to BIOS, main setup panel for your PC.
There you can find and option for switching your main GFX card.
Options will be something like: onboard, pci, agp. You should choose
PCI.

Try doing this after you insert your new PCI gfx in your computer.


Good luck,

Milan

Hello annwiles,

Checking IRQ Conflict in Windows 2000 or XP:

1. Click on the Start button, and click on the Run option.
2. When the Run window opens, please type in devmgmt.msc and click OK.
3. When the Device Manager Window opens, click the View menu. Then, select Resources by Connection.
4. Expand the Interrupt Request (IRQ) category to view IRQ assignments.
5. Once you find your adapter on the list, check if the number that is assigned to it is the same as anything else on the list.
6. If your adapter is sharing an IRQ with another device, you may be having an IRQ conflict.

Resolving the IRQ Conflict:

1. Try placing the Network Adapter into different PCI slots. By doing this, the BIOS will assign the network adapter a different IRQ.
2. Disabling COM and parallel ports, or built in motherboard devices (sound chips, etc) in the BIOS may help to free up their IRQ's.

Note: Changes to the BIOS can cause major problems with your computer. If you are unsure, please contact the manufacturer of the PC for further assistance.

3. You may be able to assign IRQ's by PCI slot in the BIOS. Please contact your computer manufacturer for more information.

That "in-op" COM port is in fact, probably defective. Had many cases where 1 works/1 doesn't. Buy a cheap, PCI COM port board, install the software, and plug away!

Lucy,

USB 2.0 cards require 2 IRQs.

• 1 IRQ supports USB 1.1
• and the other the Enhanced (USB 2.0) controller.

Installing the USB 2.0 card in a slot that does NOT share an IRQ or shares an IRQ with onboard USB produces the best result. Consult your motherboard manual or online guide to determine which PCI slot is best for you.

You should also try disabling the on board USB support from BIOS setup.

Thanks
Iqbal

Here you go, check your board version first. Both are here:

there is no PCI lock on any retail boards. But there are IRQ sharings and conflicts. Set IRQ to auto, if not, then manualy and if so, then disable a few things, just to free up some IRQs. All depends on the board, best is to consult the manual for the IRQ sharing table and work with that. (disable one SERIAL, IDE port or USB port if you need an extra IRQ) Also check for onboard equivalent to the card you are adding, disable the onboard part...
