Could anyone help me understand and resolve why FreeBSD 5.2.1 encounters a parallel port probe failure? When I boot, I do not find the predicted /dev/ppc0 and /dev/lp0 devices. If I boot in verbose mode, I the following is in /var/run/dmesg.boot: ppc0: parallel port found at 0x378 ppc0: using extended I/O port range ppc0: failed to probe at port 0x378-0x37f irq 7 on isa0 When using the KDE InfoCenter, under IO-Ports I find that 0x377-0x3bf is reserved by root0. This range would overlap the port IO range listed on the ppc0 messages. I don't know if these are related, but they seem to be to me. I found the text "failed to probe" in /usr/src/sys/isa/isa_common.c, but the source code didn't give me much to go on. I'm afraid I don't know enough yet about kernel modules and configuration to understand it. I'm running FreeBSD 5.2.1 (installed from the CD) on a Dell Dimension 8100 with 256K. Nothing too special except for a second Seagate 120GB drive (limited to 120GB to avoid having to introduce potentially incompatible hardware), and a combined USB2/Firewire card from Adaptec (which does probe successfully and appears to function correctly). It would be great actually if someone could give me two answers (I know one should not post two questions, but perhaps one can ask for two answers). First, what might be a quick fix to get my parallel port recognized? Second, how does one go about identifying and remedying port IO configuration conflicts? This is my first question ever posted to freebsd-questions. Thanks in advance for your patience and assistance. --David d.main@att.net
