Assuming your EXT2 partition is on /dev/hda2, it's easy to convert. Just type (as root, of course) "tune2fs -j /dev/hda2." You need to have a reasonably recent version of tune2fs to do this, but Slackware 8 has one that is recent enough. I personally haven't noticed any great difference with EXT3 over EXT2, but I seldom have a serious crash which is where EXT3 is supposed to really shine.
