Basic Trouble Shooting with Linux convers those that are found in RedHat version 7.3 and Fedora 8 and might also be found in newer flavors and versions of Linux that existed today.

Probe with Kudzu

  In general, when the system reboots newly installed hardware is configured by the hardware detection program provided by the Linux vendor.   On Red Hat systems, the hardware-detection program is kudzu.   It probes the system and creates the configuration file /etc/sysconfig/hwconf.   All subsequent runs of kudzu probe the system and compare the results to those found in the hwconf file.

  If newly installed hardware was not detected, place an empty file named reconfigSys in the /etc directory, as follows:

   # touch /etc/reconfigSys 

  Pls. take note that, You have to type it as is and what you are looking at is not a Type-o Error !!!   Then, reboot the system now.   This flag causes the Red Hat system to rerun the powerful anaconda hardware configuration program that is used during the initial Red Hat installation.

  IF it still not detected ?  you can manually load the device driver using the modprobe command and IF still not detected then you need to download a driver for the said device or You need to come up with one yourself.....
