I have done some tests with Win98.
Sometimes it starts asking for an address with a DHCPdiscover
sometimes with a DHCPrequest.
In the latter case using the current cvs of bootp.c there is no answer
as there is no MAC address registered yet.
Maybe it is a workaround (although a working workaround ;-) but I
propose to manage a DHCPrequest with no registered MAC address as it
were a DHCPdiscover.
The patch is here enclosed.
