IRQ conflict

Hello !
I have Ethernet PCI card which use IRQ 10, and I have MOXA serial adapter
PCI card, which use IRQ 10 too .
At first I start my network driver like this:

Net &

Net.rtl &

then when I try start Dev driver system helds-up

Dev.ser -b9600 3f8,4 -b9600 2f8,3 -b1200 d000,10 -b1200 d008,10 &

When I change Ethernet IRQ number manually to 9 confilct disappears.
But it is not very good.
Does anybody know how can I fix this problem.

THanks before.

Is there no way in the BIOS on your machine to allocate other IRQs to
the PCI bus? There should be no problem sharing IRQs on the PCI bus,
but it appears as though one of these cards is affecting the other.
If you remove one of the cards, does the other work OK?

Please post the output from ‘show_pci -vv’.

But it is only solution. Dev.ser is not able to share interrupt.
You are lucky that you are able to change interrupts in BIOS.
Otherwise you can just to disable interrupt for VGA, monitor, …
and to pray that your MOXA will pass unique interrupt.

On the other hand you can use another multiport card which has own
driver.
