Dual NIC's really slow


I have just setup Mandrake 8.0 with two nic's, one is a 3com 509 and the other is an SMC.

My network setup is:- windows machines connected on the 192.168.1 network(eth0 - 3com card), and a Mandrake 7.2 box on the 192.168.0 network (eth1- SMC card).

They both are working but when I telnet from my WinME machine to the 8.0 box the response is in spurts. It will output half the screen, wait half a second and then output the other half.

If I don't load eth1 the network response is as you would expect.

Here's the output of 'ifconfig'

Found it.

I posted the same question to Experts Exchange and someone pointed out that the SMC card was using IRQ 3, the same as the com port.

I disabled the com port in the bios and everything works fine now.
