[3c509] 3C509 ethernet card stopped working after RHL 6.0 -> 7.2 upgrade

[Alexander Karnovsky, D.Sc.]

Hello,

I have upgraded my Red Hat Linux from 6.90 to 7.2, and the 3COM Etherlink
10 ISA card stopped working. 

eth0 does not show up in ifconfig.

The card does show up in Network Configuration. I click on Edit; Network
Adaptor Configuration opens; it shows IRQ as Unknown and all other fields
(MEM, IO, IO1, IO2, DMA0, DMA1) empty. 

What values shall I put in those fields?

Note: the machine is dual-boot, Linux/Windows, and when I boot it as
Windows, the card works. 

Best regards,

Alex
