It would be an interesting exercise to try but I'm not sure there is enough demand for 386 only code to induce anyone to undertake such a huge project. All the libraries, as well as the programs themselves would have to be recompiled.

Alternative code could be written but it isn't just a matter of just setting a compiler switch I don't think. >> So while Linux itself can be compiled to run in a mode that is >> compatible with the old box, it is unlikely the rest of any modern >> distro will do so as well. >> > > Actually, I think it's quite likely that openSUSE could. > > Even if you are right about the OSS portion of the openSuSE distro, what would you propose about the NON-OSS portion of the distro? Stuff like Firefox or Thunderbird or ... well, you name it. If the source code isn't available, how do you propose to make that run on the 486? Hey, I'm all for it but I really don't think it is very likely in practice, as much as I hate to admit it. I'm an old fogey and I, like my old 486 machine, am a relic of the past and would like to feel useful well into the future, but I know time marches on so I am thankful that Linux will run on as old and varied equipment as it does and I am also glad that it will run on some of the most modern equipment available too. >> I challange a user of VISTA or even XP to take its' kernel and boot on >> a 486...never mind all its bells and whistles, just the >> kernel.... >> > > I have a suspicion you might be surprised.
