The built-in serial ports are not working under FreeBSD, although they work under Windows 95. When the system boots and displays the system configuration, it displays the port of all three serial ports correctly, but when FreeBSD boots, it does not recognize sio0 or sio1 (built-in) but only sio2 (an ISA card). I thought the problem might be because FreeBSD does not recognize by name the 430TX chipset. Does bsd have to activate these built-in ports or is this completely a BIOS problem? (and why is it okay under DOS?) Here is a partial probe list: Probing for devices on PCI bus 0: chip0 rev 1 on pci0:0 chip1 rev 1 on pci0:7:0 pci0:7:1: Intel Corporation, device=0x7111, class=storage (ide) [no driver assigned] pci0:7:2: Intel Corporation, device=0x7112, class=0x0c, subclass=0x03 int d irq 15 [no driver assigned] chip2 rev 1 on pci0:7:3 sio0 not found at 0x3f8 sio1 not found at 0x2f8 sio2 at 0x3e8-0x3ef irq 5 on isa [ISA modem card]
