Is anyone familiar with the above?
What I'm looking for, are the specs for the parameters used when registering 
a receiving ISR for particular packet types with NE2000.COM.
I can set it to direct all incoming packets to my ISR, however this seems 
like a bit much considering that I'm only interested in two particular types 
at the moment.
From what I've been able to gather, parameters are set up in registers as 
below, followed by a call to the vector NE2000 is using:
        dl  =   Number
        ds  =   Segment addr. of template
        si  =   Offset addr. of template
        cx  =   Template length
        es  =   Segment addr. of receiver ISR
        di  =   Offset addr. of receiver ISR
        bx  =   Packet Type (word)
        ah  =   ACCESS_TYPE (constant; function # of NE2000)
        al  =   CL_ETHERNET (constant; class of network)
With dl = 0, ds/si = NULL, cx = 0, and bx = 0xffff, the call completes 
normally, and my ISR is called upon receiving any packet.
Specifing a type other than 0xffff (leaving other values as indicated), 
returns an error code claiming a "bad packet type specified."
I've had no luck finding any further documentation. :-(  Can anyone point out 
the proper usage of the Number, Packet Template, and Template length 
parameters? It strikes me as overkill to receive everything and filter types 
via software if the hardware has the same capability in the first place...
...and for those of you wondering about on/off topic, I need this to help 
smooth out a class I'm writing to perform as an Ethernet packet engine. :-)
