Just a thought If the I386 (or i686, never could figure out why the name change) disk doesn't quite fit on the DVD+, and needs a DVD-, this might put some folks at an inconvenience. I wonder if the difference between fitting and not fitting is small enough, so that some amount of pruning might make it fit on the DVD+R image. Some ways to prune could be: a) Create two versions of the DVD, one with all the non-ideographic languages included, and one with the ideographic languares and a subset of the alphabet languages (English, German, French, ...) b) Find some less used but large package which presumes internet access. It could be downloaded with YUM c) Tackle the code bloat (oh yah, sure) David

> If the I386 (or i686, never could figure out why the name change)I think on CentOS/RHEL it's because they dropped support for the 586 & earlier processors. Linux wide there's been a general drop in support for 386 class machines. Something to do with recent versions of glibc and a instruction only present in the 486 and better. -- Drew "Nothing in life is to be feared. It is only to be understood." --Marie Curie

Some ways to prune could be:CentOS 6.1 i386(mostly for compatibility sake I think) will come out on 2 DVD-s also, that was already announced around a week ago, so that is already settled. Ljubomir

And I think a 120MHz variation of 486DX4. And then there was AMD's 5x86 at 133MHz. We have a few embedded boards running controllers that are still running 5x86's at 133MHz; about the same speed as a Pentium 75.> i586 is the original pentium, at 60, 66, 90, 100 up to about 133Mhz233 is the fastest Pentium MMX I've seen. AMD's K5 and K6 series topped out at 500; they're all i586-class procs. AMD's Geode in same series. Cyrix and later VIA C3-series chips go faster, but are still i586-class chips (up to 1GHz or so, maybe faster). 800MHz embedded C3's have been very popular in the embedded space. And this class of chip is what many people would like to run C5 and C6 (and they are beefy enough to run text mode for either of these, really, since they would mostly be used as network devices with no local GUI).> really, we should have compiler targets for optimizing on the P4 > 'netburst' CPUs and another for the core processors as they are all > pipelined differently.Very very true. Netburst is very different from Pentium M and Core architectures.> as it turns out, however, the core 2 and core > I3/5/7 do pretty well with pentium-II and -III style optimization > strategies, as well as, of course, the x86_64 support.Has to do with Core being descended from Pentium M architecture, which is essentially souped-up Pentium III. The history of Pentium M is a fascinating study.
