[daip] 31DEC06 install.pl : no architecture pause

[Walter Brisken]

I was trying to install 31DEC06 and get to the screen below.  I hit ? 
and <ENTER> and the options flash by so fast I cannot see them.  The code 
sniplet at the bottom taken from the current install.pl is responsible.

Perhaps a pause or "Press a key to continue" is warranted.
