Try the following instructions:

1. Click Start / Run.

2. Type "win.ini" (without quotes) and press OK.

3. Search for a line that says "DVA=0" (without quotes).

4. Add a semicolon (;) before the DVA (The line should now look like this: ";DVA=0" (without

quotes))

Q. I have Windows 2000 and all of my devices share the same IRQ, causing problems with

my GeForce. How can I fix it?

This is a 'feature' of Windows 2000 - it uses ACPI in such a way that all devices share the same IRQ, usually 9

or 11.If you don't have problems, then leave it alone, but if you do get problems, use one of the procedures

below (note that for Windows 2000 Microsoft

recommends that you disable the PNP OS option in your BIOS

before installation):

Note that Windows XP does not force all devices to share the same IRQ.
