With all these images, the g4l iso image is 50MB. > I'm a Slackware Linux user, and for ages Slackware kernels were build for i386, releatively recently that was changed to i486 - my point with this is that while my own custom kernels are slightly faster when build for my K7, they are not significantly faster than the stock distro kernels - I mean, I can mesure a difference with benchmarks, but I don't actually feel/notice the difference. So, for something like your project I'd say build the kernel for i386 or i486 and have it run on as many boxes as possible and don't loose sleep over loosing performance from that. -- Jesper Juhl Don't top-post http://www.catb.org/~esr/jargon/html/T/top-post.html Plain text mails only, please http://www.expita.com/nomime.html
