I changed the mobo in my KnoppMyth box and change was mostly succesful. Only problem that remained is that I couldn't get my network controller functional. I tested the mobo with KnoppMyth Live Frontend and controller was functional.

So, how could I get it functional in current KnoppMyth installation?

The old PHY controller was Realtek RTL8211 and the "new" is Vitesse VSC8201.

The old mobo chipset was nVIDIA GeForce 6100/nForce 430 and the "new" is nVIDIA nForce4-4X

Try running netcardconfig as root.

Done. Tool claims that there is no supported hardware present.



Do I really have to consider reinstalling the whole OS?

I really am concerned about loosing something during installation...

I would start by booting up the KM CD into "frontend mode" and running lspci | grep Ether to determine what the chipset is identified as, then searching the output of dmesg for pertinent information regarding the driver.

A quick Google for your motherboard's make/model may give you that information as well. As you didn't supply that information my Googling didn't turn anything up

This is what (or at least one of the things) upgrades are for. The R5F27 Hints include a summary of how to look for any post install tweaks you may have made to avoid forgetting. I've also discussed it in much more detail elsewhere in the forums. Start with a list of installed packages using something like:

A listing of all the file on the system might be useful to figure out what has changed later.

Finally a more targeted list of files that have changed since your install.

This last should be reviewed before you upgrade to remind you of any changes you've made.
