Something strange. It uses a DELAY() what should work independently
of any machine speed. But it was told in -hackers that it may lie
on big delays :-(

It's a common problem :-(

It's what my old 3c509 does but this new 3c509B fails. BTW, these words
"Parallel Tasking" are not about B-series only, they are about the
whole line of 3c509 since 1992 (according to the 3Com tech-tip).

I know now why it doesn't works with "plug-n-play" turned on and I hope
it will be possibly to change driver to work with it.
