Problem with SMI fix

Yep it is a Celeron.
I tried: Execute /usr/realtime-(kernelversion)-rtai/testsuite/user/latency/run inside a terminal
and yes I substituted the kernel version. Did not work. I don't have the exact error but it seemed to have something to do with the "run" command. Probably something to do with my Linux ignorance.
Just to make my life more interesting it appears that 8.04 live CD does not fit the CD-r's that I have??? Tried under Win "Free and easy burner" and Ubuntu included CD creator....
Let me get some fresh CD-R's even if the ones I have worked for 10.04 which a slightly smaller ISO...
Thanks
Tony

Hi

The iso for 8.04 is actually 2 MB smaller than 10.04 but very close to the 700MB limit of old CDs, might need to use 800MB CDs if your software won't accept it

To write an .iso to CD you can just open a terminal, cd to the directory where the .iso is and enter
cdrecord -v speed=52 fs=16m dev=/dev/sr0 name_of_image.iso

You just need to check what @cdrw and @dvdrw point to in /dev, for 10.04 dev=/dev/sr0 is probably right

I tried: Execute /usr/realtime-(kernelversion)-rtai/testsuite/user/latency/run inside a terminal
and yes I substituted the kernel version. Did not work. I don't have the exact error but it seemed to have something to do with the "run" command. Probably something to do with my Linux ignorance.

You probably didn't use sudo before it. Try just cd /usr/realtime-(kernelversion)-rtai/testsuite/user/latency then sudo ./run

SMI has never been the problem

Hopefully loading 8.04 will cure it, otherwise need to start looking at video etc

With 8.04 not fitting on a standard CD (BTW I downloaded both 8.04 and 10.04 and Linus does show 8.04 2 MB larger) I am a bit stumped. I went as so far as creating a bootable flash drive only to find out that the box allows booting anything from USB other than a flash drive.
Let me run this by you guys. I can create a DVD on my WIN box. If I was to created a system on a hard drive temporary installed on this system and than move the HD to the Linux box what are the chances of success? They are complely diffirent motherboards. Alternatively I would have to convert a SATA CD/DVD to EIDE....
800MB CD's maybe available 60+ miles from me and not garanteed to work on all drives.

Hi

From your Ubuntu installation open a terminal

Type
sudo wget www.linuxcnc.org/iso/ubuntu-8.04-desktop-emc2-aj13-i386.iso
then when downloaded
sudo cdrecord -v speed=52 fs=16m dev=/dev/sr0 ubuntu-8.04-desktop-emc2-aj13-i386.iso

I have just done it to be sure and the image writes to the 700MB CD without complaint.

(It isn't actually cdrecord that is used but I wont confuse you with that)

regards

The problem people usually have with windoze programs is that they tend to live by the mouse, so they drag and drop the file ubuntu-8.04-desktop-emc2-aj13-i386.iso
into the pane that is meant for the files to be included in the .iso

windoze then makes an iso of the iso and it ends up too big!

Somewhere in there there is probably an option to 'burn from iso' which is what you want.

regards

Some progress. It occured to me that I had a dvd/cd drive in the "pile" which I had stopped using because the door would not always open (paper clip solution) but mainly because it stopped working with CD's but used to work with DVD's. Created the 8.04 ISO on a DVD and no problem installing it. Run the latency test at first it still had the spikes. Than I doubled the memory from 1x512 to 2x512 and it seems to be hanging in there after 20 minutes where it would spike in less than 5 min.

I am not throwing any parties yet as the system has no load other than the test. The project for today is figure out how to create a load. Being a real novice at Linux just running this or that is a major project for me reading how to do this and that....
Thanks for help so far
