I am trying out Fedora5 and upon initial install everything worked perfect (minus WLAN, not worried about yet), ran the update manager and upon reboot LAN card doesn't function properly anymore and USB mouse choppy, if I roll back to previos state everything good again any hepl would be appreciated, every boots fine minus network connection, get the following message

/sbin/dhclient-script: line62 eth0 missing
/etc/sysconfig/network-scripts/network-functions:line 62: eth0: file missing

Noobie, please help, bad taste so far

I have a feeling that your update included a new kernel and the new kernel tree is missing the kernel module for your nic device.
Look at the output of "lspci -v" to find out what controller the nic uses. Then google for which device you need to use or grep the kernel source Documentation/ directory, of look in this site's HCL list.

Some NIC devices can use an alternate driver.

Once you find out which driver you should be using, enter "lsmod" and see if the driver is loaded. If not, use "modprobe" to load it.

Another possibility is that the root command "depmod -a" was aborted during the upgrade. Another is that the nic kernel module is missing from initrd. You might try running as root "mkinitrd" to update it with any new or replaced modules.

Here are the lists generated by the commands you gave me

interestingly everything works minus the network cards and if I try tp enable them then USB goes out as does sound.
I appreciate your help in fixing this problem
for reference my system is : HP Omnibook xe4100

for a later note, apparently my wireless card is loading a driver and both appear in the hardware list but neither seems to work

never mind just dumped system and started again
