Hi Miroslav,

You should look at std/iocBoot/iocStdTest.  It's an example of how to load
pid_control.db.  async_pid_control.db follows exactly the same pattern.

Also, I neglected to mention that the easy way to get the epid software
working is to include stdSupport.dbd in your .dbd file, and link with
the std library.  The Makefile commands might look something like this:
	iocxxxLinux_DBD += stdSupport.dbd
	xxx_LIBS_Linux += std
This will get you the device types that the epid record needs.

Tim
