My sound card CMI8738/C30DX PCI has irq 10 i/o 0xdc00
My ethernet card 3c509b TOP has irq 10 and i/o 0x300.

Since both have the same irq, my ethernet card did not work.
My sound card also did not work. But it is more important to me that the network card work.

Is there a way to change the irq of the sound card?
I use rh6.1.

Thanks.

It depends on the sound card. Some have jumpers, some have a DOS utility and some are 100% Plug-n-Pray. Some motherboards allow you to set IRQ's in the BIOS, so you may want to check that option if you have a PnP only card.

Question irqs conflict

The BIOS has an option to reserve an(1) irq for ISA device. Since my sound card is a PCI and with irq=10. If i reserve irq=10 for ISA, this may work, but:

1. What will be the effect of the change on the dual boot win98? which also has the same irq=10.

2. On the win98 side(same computer), the ethernet card has irq=9 but on rh6.1 side it has the value irq=10. The ethernet card was installed after rh6.1 to replace an older card. So, the irq value was not selected auto by the kernel; but because I added one line in the /etc/conf.modules:

alias eth0 3c509

I don't know if this is the correct way.

irqs conflict

In one of my computer(Dell) with win2k/rh6.1, the BIOS's list of PCI irqs shows both 3c920 ethernet card and Ensoniq multimedia sharing irq=5. In the Administration resources of win2k, it lists 3c920, Creative Audio sharing irq=9. Allthough I don't know if if Ensoniq and Creative are the same thing but at least it seems that the ethernet card is listed at TWO DIFFERENT IRQs.

I am not sure I understand this, can you explain? Thanks.
