I would like to write a packet driver for this card. What I need to know is: Do you know that Acer has their own Packet Drivers for the 5220? That is how they support the PC/TCP that they OEM from us. 1) can i modify another existing ethernet card's packet driver source (that uses the same ethernet controller chip) to make it work on mine ? The 5220 is a close relative of the original Nat Semi DP839EB design, which was cloned by Novell, D-Link and others. So, you'd do best starting with the NE-1000 or D-Link Clarkson drivers, and proceeding as the Acer manual suggests (they made at least a few changes). 2) what other ethernet cards uses the NS8390 ? The 3C503 and the Wd8003 both use it, but they're less closely related to the original design (which Nat Semi gave away with sample chips...). James B.
