Hi, I updated from red hat 9 to fedora last night and I have the following problems ( I have asked them on www.linuxquestions.org, if you have read it, I sincerly apoligize for bothering your again ). The machine is a PIII-450 with 768MB memory. I use a netgear router which connects this one and a newer P4 machine running windows xp to internet. 1. I could not connect to internet from fedora. eth0 interface is not brought up. ( my card is not made by 3Com, as someone point out might be the problem ). The Xp machine connects with no problem. >From the logs, I noticed that modeprob is looking for /lib/modules/2.2.20.8/modules.dep. And I only have /lib/modules/2.2.22.40.ntpl/modules.dep. I don't even have the 2.2.20.8 directory. I create 2.2.20.8 directory and copied the /lib/modules/2.2.22.40.ntpl/modules.dep over. Doesn't work, said something about "not ELF format". I then delete the copied modules.dep file and create a symbolic link to /lib/modules/2.2.22.40.ntpl/modules.dep. Doesn't work either, and this time modules.dep in /lib/modules/2.2.22.40.ntpl/modules.dep is empty ! How do I generate a modules.dep file ? Is modules.dep generated at boot time ? How does modeprob work ? Is there a way to specify which directory to look for modulles.dep file ? 2. My /usr directory is mounted on its own partition ( on a different hard disk ). In the /etc/fstab file, it looks like this /dev/hda5 / ext3 defaul 1 2 /dev/hda2 /boot ext3 default 1 1 /dev/hdb6 /usr ext3 default 1 3 Fedora couldn't mount this drive ! saying the kernel does not support ext3 filesystem. Is it, really ? As a result, besides losing a bunch of shell command, X window won't start. I have to change to /dev/hda5 / ext3(!) default 1 2 /dev/hda5 /boot ext3(!) default 1 1 /dev/hdb6 /usr ext2 default 1 3 then x-window works. Notice it can mount / and /boot as ext3. What went wrong here ? Does it also have something to do with run levels ? like at different run levels, different modules will be loaded ? I have limited knowledge of linux, particular challenged with feroda :) . Any help will be greatly appreciated ! Thanks, Xiaohu
