I have a Cybermax desktop with Windows 98 on it. I would like to install Fedora 13 on it, I've gone into the Bios Features Setup and changed the boot-up sequence boot to CD-Disk drive, C, A. The boot-up starts okay and soon it goes and says the CPU Kernel isn't compatible. Saying it needs "cmov" to physically boot-up. No, I am not wanting to use a Virtual Machine, I want Fedora 13 on the physical Hard Drive. I would like to know if there is a way to incorporate "cmov" into the system, most preferably with a piece of hardware.

cmov is a feature of your CPU, older CPUs (AMD: pre-Athlon, Intel: pre-Pentium Pro) do simply not have this feature. You can try a distribution that is aimed at older machines, like antiX.

Fedora 13 is many many years out of date, don't use it.

Since this is an older system you should use a smaller footprint distribution like Arch Linux, or Archbang.

Both, Arch and Archbang (since it is based on Arch) are optimized for i686, which is exactly the problem here, since the CPU of the OP does not support cmov, which is part of the i686 instruction set.

I'd doubt a Win98 machine without cmov (so its maybe some VIA CPU, or pentium 1, or AMD K6, or something even earlier) has the RAM to run most or possibly any current linux version.

How much RAM do you have, and what CPU?

The cmov instruction came in in the Pentium Pro, so you have a Pentium I. This is a feature of the CPU, so nothing outside the CPU is going to help.

Bodhi and AntiX both come with a suitable version of Linux. Bodhi will just about run in 128MB, and AntiX will even do quite a bit in 64MB (poor internet access, though). Don't expect speed, though: both actually recommend a PII. The bottom line is that you cannot expect a 2013 Linux to have the properties of a 1995 Windows.

Other Linuxes (e.g CrunchBang, Mint Debian edition) are suitable for a PI but they all require more memory.

Need more info from SKOLROK on ram and computer detailed specs before recommending AntiX since I am a team member. Base install or better yet, core install would be the way to go if a older unit. Links 2 and Dillo will be the biggest browsers from the sound of this thread. Even in Tiny Core.

That computer you have has got to be really really old. No offense intended, but you could probably go to a thrift store or electronics recycling center and buy a better one for $10. Some things are just not worth the time and effort it would take to pursue them. Installing a modern Linux on that computer you have is probably one of those things.

I second haertig. Even if you managed to install a modern Linux on that machine, it would be a pain to use it.
Get at least a Pentium 4 machine - and even Core 2 systems are thrown away by many people nowadays.

antiX, slax, porteus, puppy linux

Before you throw your machine away, try any of these. One of them is bound to work very well on your machine.

Such an oldie would almost surely need a customized kernel to work. Most modern distros won't provide such a kernel out-of-the-box; you will need to download the required kernel yourself. To the best of my knowledge, if you want to avoid this, Slackware is your best bet. Two years ago, I managed to install Slackware in a 20-years old Pentium without needing to search for a kernel (Slackware already had one for that, in contrast to several other distros I tried.) I assume Slackware is still supporting such old machines out-of-the-box even today. Note, however, that although Slackware is a very respectable Linux distribution, it is not exactly the most user-friendly out there.

Also, the computer might be very old, but despite what many people think, it might still be useful. With a lightweight display manager, such as fluxbox, windowmaker, blackbox, and many others, you will have decent performance in a graphical environment. Of course, the computer won't run bloated window managers like KDE or Gnome, but, if you ask me, that's not a bad thing. It won't be the best machine to run modern games as well, but it will still be a nice computer for development.
