In ms/dos terms. If your laptop has serial ports on it then the com1 & com2 config options you see in the bio's are talking about them and not your modem. In this case you want to disable them in the bios so they can be used by the modem. In FBSD kernel source you may have to comment out the sio1, sio2, & sio3 and compile the source. During the power on post process your laptop should display some information about what hardware the bios found before the operating system starts to boot from the hard drive. IBM some times default to turning this info screen off so the user don't see it. You can turn it on in the bios. If you have not, I would do so now as you need to see the info it shows about irq assignments to the modem and other hardware. If you don't see your modem here then your PC did not find it. -----Original Message----- From: owner-freebsd-questions@FreeBSD.ORG [mailto:owner-freebsd-questions@FreeBSD.ORG]On Behalf Of leegold Sent: Sunday, January 13, 2002 10:20 PM To: Kevin Oberman Cc: freebsd-questions@freebsd.org Subject: RE: what does my dmesg say? >===== Original Message From "Kevin Oberman" <oberman@ptavv.es.net> ===== ...snip>> >> > sio0: configured irq 4 not in bitmap of probed irqs 0 >> > sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0 >> > sio0: type 8250 >> > sio1 at port 0x2f8-0x2ff irq 3 on isa0 >> > sio1: type 16550A >> >> sio0 is most likely your modem, but it must be an ancient one to be a >> plain 8250.

In dos lingo I need to get com1 working? I have an isa hardware modem, I think it's jumpered for com1. In any event, whatever I have it jumpered for - I have to make sure the bios that port enabled?
