Fedora 6
realtek high def integrated on intel motherboard 945gc

installed driver from realtek v3.6
now fails boot looking for libasound.so.2 (file not found) have to go to emergency terminal mode
have found another driver for sound v4.06

how can i get around the boot failure, it occurs before interactive setup?

The "file not found" means the package is not installed. To find which package, highlight/copy/paste "libasound.so.2" (the missing files) into this rpm search utility. At the top of the next page is a link to the FC6 specific package where you can download it/them from, pick the one that matches your architecture, you more than likely need both the i386 & x86_64 packages if you're running x86_64. Install them with command (replace "packagename" with actual package name):
Or yum if you have a connection and you have atrpms as one of your repositories.

Was a good reason to reinstall as I needed to modify partitions anyway. Sound now works with package driver. Thanks
