Realtime system did not load...
System: Pentium 3, 256M RAM, battery is dead
It seems that this should start anyway. Here's the log:
Thanks for any help provided.

Then I installed it with overwriting Win and got the same error.

The load aborted because of a segfault but I think this may be the crucial lines from dmesg
insmod: error inserting '/usr/realtime-2.6.32-122-rtai/modules/rtai_hal.ko': -1 Operation not permitted1556
[ 187.716888] RTAI[hal]: ERROR, LOCAL APIC CONFIGURED BUT NOT AVAILABLE/ENABLED
see wiki.linuxcnc.org/cgi-bin/wiki.pl?Troubl..._t_run_missing_lapic
dmesg shows the rtai kernel was running so that is not a problemYou might have a non-realtime version installed as well.
However you are trying to run 10.04 on a P3 with 256MB RAM. Once you manage to get started, you will probably find it runs like s***t
I would recommend you install 8.04 (which will probably cure your LAPIC problem because I don't think it affects 8.04) and preferably put another 256MB stick in.
Or at least ensure there is a good swap disk and be prepared to be patient!

My base problem was that the software was EMC. I loaded it on a laptop and I expected to see "LinuxCNC".
So, I made sure I dll'd V3 and tried it on a laptop and it worked correctly.
Then I went back to the P3(s) and tried it again. It installed correctly on them but it generated the same error on executing "Axis". Those are both Intel P3 boards so it looks like LinuxCNC is not backwards compatible.
I guess those motherboards will be relegated to the SMT practice pile.
The driver board I have is an eBay stepper board that is a fairly well designed Chinese board It has protection on the DB25. So I'll work with that on a laptop until I find a P4 with the APIC enabled. There must be one around here somewhere, let me see....oh, I'll do that later.
Thanks for the help.

You appear to be under a very common misapprehension about the link between Ubuntu version and Linuxcnc / EMC2 version.Those are both Intel P3 boards so it looks like LinuxCNC is not backwards compatible.
Ubuntu 10.04 is the operating system, equate that to Windows 7 say. Ubuntu 8.04 equates to say Windows XP.
Linuxcnc (previously called EMC) is software that will run on either 10.04 or 8.04 with a special kernel which exists for both. There is no backward compatibility issue.
The problem that you posted about can be solved by following the link I gave you re LAPIC.So I'll work with that on a laptop until I find a P4 with the APIC enabled.
You might have to do exactly the same with another machine.
The larger problem is that you are trying to run the equivalent of Windows 7 on a machine that will only just run XP properly.
If you install the Live CD based upon Ubuntu 8.04, yes it ships with EMC2 2.3 .
But all you then have to do is upgrade this to the latest Linuxcnc 2.5.1 following the steps on the site.
You will be installing an operating system far more suited to the low power of your machine and can still run the same CNC software.
Whether the latency of your P3 is any good....well thats another matter

Thanks, I'll do that. I would like to put those P3's to work.
I had understood that EMC was disparaged, but I didn't understand why. Maybe there should be a web page describing the differences between the operating system environments and the differences between EMC and LinuxCNC and related issues.
I'm not concerned about some of the time response components. I understand the user interface will be slower, that I can live with. And I would expect the operation to be slow also. It would see that would have been an issue with earlier versions if it introduced errors, so that should have been addressed.
Thanks, I have a better understanding but I still have more to learn about this.
