My question is, how do I get a 64 bit >kernel installed? You'll need to reinstall with an x86_64 fedora.... and while there are *some* advantages to running a 64-bit system there are also downsides still. Advantages (that I can remember):- You can use huge amounts of memory efficiently (i.e. if you have more than 4Gb or memory) Some other things may run more efficiently Disadvantages There may not be all the drivers you need available in 64-bit (maybe less of an issue nowadays).
Both the 64bit and the i386 kernels have the exact same drivers. If you can boot an i386 kernel, you can boot a 64bit kernel.Now, there may be bugs in the 64bit versions of the drivers, but that's another story.
