I think you're out of luck with the 3C515, friend.  

man ep:

     The 3c515 is an ISA 10/100 card with DMA capability.  The chipset is sim-
     ilar to that of the 3c905, with some changes to make it work with the
     more limited ISA bus address space.  This card is not currently support-
     ed.
