I changed the IRQ in the tool under the XWindows App - changed it to 10,
then rebooted and I can
now ping no problem at all ;)
My performance seems low, (I expect i'm not in full duplex mode... not a big
deal at this point)

Thanks to all.... now off to the next problem ;)

Not on ISA bus. At least not reliably. The 3c509 is an ISA card.

On ISA you have to set it on the card or use "Plug and Play". Of
course, it has to be right in /etc/modules.conf as well if you change it
on the card.

Also, "lspci" won't show ISA cards.

But certainly not with the card he's trying to use. ISA doesn't support
shared IRQs, unless using specifically designed HW (like serial multiport
cards etc.).

well you are using an ISA card afterall :D
