  Hello.  I finally got around to installing the chio driver that you
had mentioned to me about on 2.1.6.1.  After replacing the appropriate files
(the only unexpected thing was to copy chio.h to /usr/include/sys) I was able
to load/eject tapes on my 4mm DAT changer (Archive Python 24889) correctly.
I haven't had time to fool with Amanda to use chio yet but I think
everything is easy from here.  Thanks for all your help!

  One question: I am not familiar with the terminology used in the man pages
(picker, slot, portal, drive).  I can load/eject the tape by moving between
slot/drive.  Can you tell me what are the purposes of picker/portal?

  PS:  I am sending a copy of this to FreeBSD mailing lists because I've
seen the same question asked in the archives but no definitive
answers.

  Thanks again,

  Tim
