Hello,
I am having a hardware problem with my new FreeBSD installation. I
cannot get the system to recognize my the port which my modem is on. I
am using version 4.2-RELEASE. My system in a 700MHz Intel on a Tyan
Motherboard. 384MB RAM. For what it is worth, the modem is not a
winmodem. It is some generic 56K.
The error message is this (from dmesg):
sio2: configured irq 11 not in bitmap of probed irqs 0
sio0 and sio1 or both configured fine. To get to this point, I had to
rebuild and install my kernel after enabling the COM3 line in the config
file.
I read every scrap of info on this in the newsgroup and mailing list
archives. Everyone is saying that I have a hardware conflict, which is
what it seems, but I have tried using another irq (5) to no avail. I
even disabled COM2 and set COM3 to irq 3 and that gave me the same error
message as well. I tried manually setting the irq in my BIOS to no
avail. There must be another thing that is blocking the device. I am
also running RedHat Linux, Mandrake Linux, Win2000 and Win98 and they
all are using the modem on irq 11. Is there a way to get FreeBSD to list
all of the irq's in use? Is there something else that I can tweak in
order to get COM3 cooperating?
Thanks a lot,
I'm desperate,
Jon Collis
