have you read my report carefully?
when I run stock program (compiled for everything I beleive),
it can't recognize the card.
when I run custom-compiled version with only NE enabled
(I am sure my card is NE-compatible), it hangs the system.
I have tried to locate exact place of code where it hangs,
and I hope I succeeded.
What hack do you mean? I can't understand, please explain.
can NE-2000 board be used by FreeBSD's netboot loader
in 8-bit mode?
