Hi, First I have a ABIT AV8 Motherboard with a AMD-64 3000+. I just installed Fedora Core 4, 32 bit version, and am having Modem problems. I have a External serial Motorola ModemSURFR so should not have any problems. The installation did not find the modem and just running Kudzu does not eather. It is not listed in /etc/sysconfig/hwconf at all. If I tell kudzu to scan the serial port by running "kudzu -b serial" it will find and configure the modem which will then work but then it un-configures everthing else. If I run kudzu again normally it disables the modem. At first I thought that it must be running in safe mode which disables scanning the serial port as well as DCC and PS/2. But just running kudzu does probe the DCC bus so that must not be it. I am not sure but this is a change from FC3 but I have noticed that Kudzu does not act like it used to in that if you remove a piece of hardware it will not ask if you want to remove or keep the configuration. I thought this might be a change to improve boot speed but then I noticed a post where someone wanted to know how to didable this feature in FC4. Has anyone else had this problem? Any ideas as to what might be going on? Is there a way to configure the modem that Kudzu will not mess with? Thanks for any help Roger
