so is the m7i :)

i am not expecting active support of 14 or the m7i.  i am expecting an
archive of historical releases just as application softwares have.

exactly my fear.  it was running 14 successfully as the disk drive
failed.  i want to run 14 when the new drive is installed (in the next
day or two).  this seems a reasonable desire.

which is somewhat reassuring, though the start/size of #1 is a bit odd
