Hello: I have seen many messages about the problem of configuring a pci modem in FreeBSD, and in particular a few about the ``US Robotics 56K Performance Pro Modem''. I am using this modem with FreeBSD 4.2, and maybe the following information is useful to those who are having problems with that and similar modems. My system has a TYAN (S2390) motherboard: 1 AGP 6 PCI 1 ISA (shared with one PCI) I have a 4-port serial card in the ISA slot, and the following in four of the five available PCI slots - ethernet - modem - sound - scsi in that order, from top to bottom. When installed the modem, it was always recognized without doing anything in particular to the kernel. Originally, I had configured and enabled sio0 and sio1 as usual, then sio3-6 for the 4-port serial card, and sio2 was configured but disabled. The boot message that I was receiving regarding the modem was similar to one below (look at the three lines that I have marked with '-->'), but with ``sio0: moving to sio7'' instead of ``sio0: moving to sio2''. However, the modem was not working. I could not talk to the modem via cu -l /dev/cuaa7 (after making MAKEDEV cuaa7). Then I recompiled the kernel with the sio2 lined commented out, and the boot message regarding the modem became as it appears now, which is included below. Still, I could not talk to the modem, but it was obvious that the modem was being recognized. Then I took all the PCI cards out of the machine, rebooted, and finally I could talk to the modem, normally. I dialed out, used ppp, whatever. The modem is supported in FreeBSD 4.2. The problem was some sort of conflict with the other cards. I started by installing the remaining cards one by one, rebooting and trying the modem until I hit the problem again. At that point the BIOS was assigning the same IRQ to some of them, including the modem and the video card. Therefore, it is a question of going to the BIOS and make sure that it assigns a unique IRQ, at least to the modem, since FreeBSD uses whatever the BIOS decides to assign. The problem was solved for me when I disabled the IRQ assigment to the video card. I hope this is helpful to some. The following is the current boot message. Regards Jose.
