How to edit IRQ in NT ???
Hi,
After installing a PCI network adapter, I installed a AGP VGA display card in the NT Server. Then there was a conflict between them and the PCI network adapter could not work at all. Therefore, I thought it's an IRQ conflict problem and I wanted to edit the IRQ manually. However, I just can't find any way to edit the IRQ manually in NT. Would you guys please tell me how to edit the IRQ manually step by step?
Thanks!!!

In NT server u can edit in control panel - ports u can edit IRQ settings
Why don't you try it in the registry?
HKEY_LOCAL_MACHINE\SYSTEM\
\Services\adapter name#\Parameters
Value: INTERRUPTNUMBER actual IRQ value...
HKEY_LOCAL_MACHINE\SYSTEM\
\Services\adapter name#\Parameters
Value: INTERRUPTNUMBER actual IRQ value...
Though I would suggest not to do the above registry changes... I think that might be easier if you do it carefully. But the best and recommended way to do this, is to remove all the installed network card drivers and reinstall them with the right settings. It varies for each card. Some cards come with their own software to change the card settings like IRQ and base I/O address and so on... For some, you can change them in the CMOS setup.Well, you choose how to do it. It might not be a bad idea, to see which device is actually conflicting with your NIC. If it is a mouse or something like a modem (I mean serial devices or Comm devices), you might a find an easier solution. I guess, WINMSD.EXE will tell you about the conflicts, too. Check it out...
Good luck..

Ps: EZHIL, you can change the IRQ settings of serial ports through PORTS applet in Control Panel. Not for the Network Cards.

yes snimmaga, I am with you! The only thing I can change in PORTS applet in Control Panel are those serial ports. Anyway, snimmaga, thanks for your suggestions. My problem is the AGP VGA card always occuppied the PCI NIC's IRQ. Whenever I set up the VGA card driver, the NIC will lose its IRQ and I can not use the NIC again. I really don't have any idea on that. Anyway, I will try your suggestion tonight see if it works. Thanks.

Hi snimmage,
I tried to edit the registry as you showed me. However, I just can't find the adapter name# under
HKEY_LOCAL_MACHINE\SYSTEM\
\Services
why?

Hi Blackman,
How do I put a /PCILOCK option in boot.ini? Do I just type "/PCILOCK" at the end of the boot.ini file or what? Can you tell me in more detail? thanks.

1) Remove the read-only attr. from C:\BOOT.INI
2) Load it in Notepad (or another editor)
3) Now, in the section [operation systems], there are a number of lines. These are the bootoptions shown by the NT Loader. The first is usally the default. At the end of the line, you put a /PCILOCK switch
4) Save the file and set it read-only
5) Reboot and choose the line you just modified

Instead of locking down the entire OS intervention into the PCI business, isn't it a good idea to go ahead and change the BIOS settings on the box?
FOKCHI, usually you use CTRL, ALT, DEL, INSERT, SHIFT, F10 key combinations to get into the CMOS setup. Get in there and change the interrupt settings for the card.
Good luck..

Ps: though, sincerely, /PCILOCK is a good idea too. It didn't strike me before. Good thought, BLACKMAN.
