[Vivek Vaid]

It worked exactly as described below. Actually I should have written when
i got it working with the help of Eric, 2 days ago.

Thanks a lot! 

(pls. read at the end about my system config. and ne2k diagnostic
programs)

I have tested this NE2K ISA card with 486dx2, and 486dx4. 
th4 486dx4 motherboard did not have any pci slot.

Since i have lot of isa ne2k cards in my lab, i had downloaded various
utilities to find out their base IO address, and irq number. 
These utils are for dos. (I have for: Realtek/Dlink, Readylink)
If anybody needs them, please email me.

I used ReadyLink card with rtems.
Putting the io address and irq in settings is necessary in all OSes (Win ,
linux,    Rtems (in the ne2000.c file)).
