Exclamation IRQ Conflict (solved)


I have an Intel AC'97 audio card and a Dell Truemobile 1350 wireless card (Broadcom BCM4306 chipset) through NdisWrapper. However, the IRQ on both of them is 7, and everytime I start up, it tries to bring up the wireless card, and it freezes. The only way to avoid it is to enter interactive mode and skip it. The only workaround I know of at the moment is to change the audio driver, and the next time I start the system it works. They both work fine under Windows XP. I assume it is because I'm using NdisWrapper, so is there a way to fix that?

I'm using Mandrake 10.1, Kernel 2.6.8.1-12mdk.
I'm using NdisWrapper 1.0

Ah, I figured it out. All I had to do was change the "acpi=on" to "acpi=noirq" in the lilo configuration.
