I don't have that running here. This is pretty much what we expected. If you were to mount sda1 onto /mnt/olddisk and look in the /mnt/olddisk/boot directory, you would likely find your BDI kernel, with a lower version number, probably 2.6.12 > [EMAIL PROTECTED]:~$ > > Now with 'ls /mnt/olddisk' I get some directories - boot, dev, home > etc...all in pretty colours. > > Now with 'ls /mnt/olddisk/home/dave I get some more directories one of > which is emc2. > I'm confused now - why is emc2 in the olddisk, I really did not expect to > see emc2. > This is everything that was part of the EMC2 install that was on your BDI system. So, of course, it has your OLD emc directory. You have TWO COMPLETE, but DIFFERENT file systems on your hard drive, in different partitions. One is old, from the BDI system (sda1) and one is newer, from your Ubuntu system (sda5). Much of what is on the old partition is obsolete. the only thing in the emc2 directory that might be useful is the ini file that you actually used on your machine. Don't just copy it over, as a lot of stuff has changes, such as the introduction of HAL But, you might want to print out a copy of it to save the variables you set up for your machine. Any CNC files for parts you might want to make again, or any other custom software or G-code shoudl be copied over to your user directory on the Ubuntu system. > I've checked a few things like sda5 ... says '/dev/sda5 is already mounted > on /mnt/olddisk'. > I thought sda5 would be your Ubuntu system's main directory tree. I would have expected it to be mounted to /, not /mnt/olddisk. But, maybe it is /dev/sda2 that is the Ubuntu main file system. If you just type ls / You will see a simlar directory tree, and it will ALSO have an emc2 directory, that is your NEW EMC2 directory as part of the Ubuntu install. They will have almost exactly the same file names, but some will have newer dates - those would be the files updated since the BDI. You can find out what is mounted where by looking at /etc/fstab, with a command like : more /etc/fstab The first column is usually the /dev/xxx partition id, although it can also be the volume label of the FS. The second column is the mount point, like /mnt/olddisk, or / for the system's main file system. Jon Hello Jon I think I may have confused you, or at least I am. EMC2 was installed along with Ubuntu from the "live CD" a couple of weeks ago. (This is great runs well - no problems):-) BDI/EMC was installed a few months back from the "Sherline CD" it was the old EMC not the new EMC2. Does that make more sense, or am I really lost. Some more help please Jon Regards Dave Hey I can use a slide rule! ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
