Actually there is no difference in the hostmot2 watchdog feature firmware wise between any of the cards (7I43/5I20/5I22/5I23) I doubt there is any driver difference either as the mid level (hostmot2) code is the common for all cards, the only difference between PCI and EPP cards is the lowest level data transfer method. It is this transfer method that limits EPP mode to single thread access. > > Ted. > > > > ------------------------------------------------------------------------------ > This SF.net email is sponsored by: > SourcForge Community > SourceForge wants to tell your story. > http://p.sf.net/sfu/sf-spreadtheword > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users > Peter Wallace Mesa Electronics (\__/) (='.'=) This is Bunny.
