I thought about unpacking a stage1 tarball, changing CFLAGS, calling bootstrap.sh and doing an emerge -e world, but this would overwrite things in /etc and clutter my file system with more things I do not really want, like creating entries in /dev. I would rather like to keep the current setup as it is. use knoppix. If you don't want to reinstall everything and the XP is just a temporary replacement, get a knoppix livecd. It lets you save things to a file, if you want to. I think that I saw a howto once about what to do in such a case, but at that time I did not need it, and now I cannot find it. the howto is: remove the system and start from scratch. BTW: What exactly are the benefits from using march instead of mcpu? Is there a noticeable difference in speed anyway? With mcpu I would not have the trouble I am having now... Your trouble started, when you switched to a completly different cpu... mcpu = only rearranging stuff so it might run better on the cpu specified. No instructions and features used, that are not available on all the other cpus from a family (in theory, a binary built with mcpu=athlon-xp should be able to run on a i486). march = optimizing for the specified cpu. Using all features and instructions available, building stuff not able to run on other cpus. (so a resulting binary of march=athlon-xp won't run on a i486) usually march is faster on the given cpu, mcpu is more compatible. -- [EMAIL PROTECTED] mailing list
