Yes!  I initially started out using the "server" option but ultimately
wound up using the "client" option.

The so called server option seems to reduce the number of interrupts in
a particular time window so that a DOS/NOVELL server can have some cycles
for other things.  I think it just drops packets man!

The client options allows the card to run flat out.

It makes a *big* performance difference on sustained ftp.

For some reason FreeBSD didn't seem burdened by the processor overhead
that 3com was worried about :-)

A hardware kludge to cover for lame software is what I think it is.  Turn
it off.
