Yes, the parport stuff has changed between emc2.3 and emc2.4 and there are also differences between an 8.04 installation and a 10.04 installation.
In emc 2.3 and earlier, emc's parport drivers would not cooperate with the linux parport drivers, so the linux driver was disabled by default. In emc 2.4, emc gained the ability to cooperate with linux's parport driver. The anticipated benefit was primarily to make it easy to specify pci parports, because you can call them parport 1, 2 and so on instead of 0xe800 or a raw port address. so systems that are initially installed with 2.4 leave linux parports enabled ny default (but 2.3 to 2.4 upgrades don't, I think) We also hoped for better detection of epp-supporting parports, but this has proven to be untrue. See the long "d510mo" threads for more on this. the "mode 4" message is related to this--linux thinks your port is not epp-capable. in the latest release, 2.4.5, I think the problems working in cooperation with linux are solved, but if not, your final option is to disable theb linux parport driver by editing the file /etc/modprobe.d/emc2 or emc2.conf and removing a #. reboot after doing this, and linux will get out of the way of emc's use of the parport. (of this does turn out to be necessary, let us know--we may be able to find a solution, like we did for d510mo) Jeff ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
