Hi Keely,
I think your problem has little to do with e-smith. If your card is not detected by the bios of your motherboard, than nothing will ever happen. Since you are using a P66, you have a old motherboard I'd guess. Try to tell us more about it ( type/make/ etc) Maybe someone will remember something that will help you.
My first step would be to look in the bios to see if there is anything that resets the allocation of irq's. During boot up, some bioses do show what hardware has been assigned what irq.
If all else fails, try to do a window9x install and see if the card gets detected. If so, note the irq's etc. E-smith is really a Redhat distribution, so the hardware detection has nothing to do with e-smith. If Redat can't find it, it means it ain't there, for whatever reason..
Go back to the very basis basics and start from there..
Do describe your hardware in some more detail, please?
good luck
