That's expected, because -net nic -net user is identical to
passing no -net options. Try a different NIC, eg with
-net nic,model=ne2k_isa -net user

since your earlier test suggested that your guest was happier
with that card rather than the default e1000.

There is probably a bug in our e1000 network card emulation, which
is triggered by whatever your FreeDOS guest's network driver does
but not by the Linux e1000 driver's behaviour. Or possibly the
FreeDOS e1000 driver has a bug. Either way, what I suggest above
is to try to work around this by trying another NIC, which will
mean both that QEMU is using different network card emulation and
that the guest is using a different driver.
