Oh oh. I had serious trouble with a IBM/Cyrix 6x86 cpu and gave up
trying
to install Red Hat Linux 5.2 on it. I saw something about changes to
the
kernel so that Cyrix CPUs would work with later versions of Linux, but
have not tried them. I have stuck completely with Intel cpus since
then.
Is the 586 a real Pentium, or are you talking about a Cyrix 5x86?
The 5x86, I think, is the same architecture as an Intel 486, just
faster.
The Linux memory pagesize is different for 486 and Pentium systems,
and causes some problems in allocating the shared memory region.
That problem has been solved, but a 100 MHz Pentium is just about
the slowest you want for servo systems, and you want even more for
a stepper system.

You need the baseline workstation install, plus the Xwindows
system, plus the Xwindows developer libraries (unless you only
will be using pre-compiled EMC versions). You also need the
TCL/Tk support, software development support, I think.

EMC, on any system with encoder feedback, can be used as a DRO,
whenever the axis drives are off.
