Hi all,
Maybe someone can see through this wall I'm running into. I'm trying to
get the netboot code to run on SMC/WD Network cards off EPROM, but am having
no luck. Here is a brief rundown of the facts:
o OS version is FreeBSD 2.1.0R
o The nb8390.com boots fine, comes up diskless with no problems from DOS.
o The EPROMs are Intel 27C128 (16k).
o The same EPROMS work fine in NE2000 based cards (nb8390.rom has both
the WD and NE options set).
o The NIC cards I've been using are WD8003EP and SMC Elite16.
o The NIC cards are configured for 16k ROMS.
o The NIC cards are jumpered for ROM address 0xd8000.
o DOS debug shows all 0xff at 0xd8000 ( d d800:0000 -> FF FF FF FF ... ).
For some reason the NIC does not seem to be address decoding for the
ROM memory range.
o The netboot Makefile has WD_DEFAULT_MEM set at 0xd0000.
o The machine boots directly from disk after the POST with no messages.
o The PC is a 486DX66 with 8Mb of RAM, all shadow ROM disabled.
