a) conflicts with network cards or soundcard would be my guess, (IRQ) b) remove the modems and make SURE that on board serials are disabled c) maybe the modems are conflicting with some device's port address? good luck Alfred perlsta@sunyit.edu > Here's a wacky one ... > > I have two systems both running FreeBSD 2.2.1 with four serial ports > enabled. > > athena is a 386/33 with 16M, ISA bus, two dumb serial ports, > two internal modems with FIFO UARTS.
