I'm trying to install ndiswrappers in FC4. I followed the installation manual in their site, but specifically here is what I did. First I extracted kernel-devel-2.6.11-1.1369_FC4.i686.rpm. Then I did "rpm -Uvh kernel-devel-2.6.11-1.1369_FC4.i686.rpm". It said that it needs hardlink. I extracted hardlink (from cd 1 I think). Then I did "rpm -Uvh hardlink-1.0-1.13.i386.rpm". This installed, then the kernel installed. Yay! Next I attemted to install gcc using same method as last two packages but this didn't work too well (had too many dependencies), so I then decided to "system-config-packages" the development-tools installed fine. Thinking that I didn't have openssl-devel I tried to uncompress it from a cd (#1 I think) and then tried to install it but told me that it already is installed. Then I downloaded ndiswrappers-1.2 from their site. Did: then I linked ln -s /usr/src/kernels/2.6.11-1.1369_FC4-i686/ /lib/modules/2.6.11-1.1369_FC4smp/build (first time around I mistakenly linked it to 2.6.11-1.1369_FC4/build, but then I uninstalled it then did it again with the same results) make clean su - <pass> make make install ndiswrapper -i driver/ir/bcmwl5.inf This is what it said: Installing bcmwl5 Forcing parameter IBSSGMode|0 to IBSSGMode|2 Forcing parameter IBSSGMode|0 to IBSSGMode|2 Forcing parameter IBSSGMode|0 to IBSSGMode|2 Forcing parameter IBSSGMode|0 to IBSSGMode|2 Forcing parameter IBSSGMode|0 to IBSSGMode|2 Forcing parameter IBSSGMode|0 to IBSSGMode|2 Forcing parameter IBSSGMode|0 to IBSSGMode|2 Forcing parameter IBSSGMode|0 to IBSSGMode|2 Forcing parameter IBSSGMode|0 to IBSSGMode|2 Forcing parameter IBSSGMode|0 to IBSSGMode|2 Then I checked to see if the driver was installed. Yup. [root@WarpPower ndiswrapper-1.2]# ndiswrapper -l Installed ndis drivers: bcmwl5 driver present, hardware present But here is where it failed: [root@WarpPower ndiswrapper-1.2]# modprobe ndiswrapper FATAL: Error inserting ndiswrapper (/lib/modules/2.6.11-1.1369_FC4smp/misc/ndiswrapper.ko): Invalid module format [root@WarpPower ndiswrapper-1.2]# Sorry for such a long message but I hope someone might be able to help out. I googled this alot, but to no avail. Most people had this because they had update kernel. Thank for any suggestions, -Gezim
