than magnitude 14.3,  it should show A2.0 stars.  (If the current
magnitude limit is brighter than this,  there is probably not much
point in showing the Ax.0 stars.)  It also tells Guide that the Ax.0
files can be found in the \a2 directory of the C: drive.

   Once you have done this,  you can ignore the "Get Ax.0 from CD-ROM"
and "Get Ax.0 via Internet" options,  because the Ax.0 stars will simply
pop up automatically when you get to a faint enough magnitude limit.

17c:  INSTALLING TO THE HARD DRIVE     

   By default,  Guide only installs a few megabytes of essential data
to the hard drive,  and the remainder of the data it needs is read from
the CD-ROM on an "as-needed" basis.  This is fine for many uses,  but
there are several possibilities for installing more data,  or the
entire first CD-ROM,  or both Guide CD-ROMs,  or bits and pieces of
both CDs,  to the hard drive.

   To see this,  click on "Extras... Install to Hard Drive".  Guide
will give a list of assorted items that can be installed from the
hard drive.  If you just checked the first item,  "Minimum Hard Drive
Install",  Guide would copy over a few more megabytes that would be
enough to let you run the program without needing the CD-ROM.  But it
would be a very "minimal" installation:  you would see no stars past
magnitude 7.0,  many datasets would not be included,  and many functions
would be unavailable.

   Checking subsequent items soaks up added hard drive space,  but
gives you those added functions.  Check all the items,  and Guide will
copy over everything from the CD,  consuming about 660 MBytes.  (Of
course,  you can return later and un-check some or all of these items
to reclaim the hard drive space.)

   Guide will still check the CD-ROM drive at startup,  just to see what
data is available.  If you've installed only a few items,  but Guide
realizes the first Guide CD-ROM is in the drive,  it will get what it
can from the hard drive and access remaining functions and data from
the CD-ROM.  If you've installed some or all of the items from the first
Guide CD,  and Guide detects that the second Guide CD is in the drive,
it will access items from that CD.

   The second Guide CD contains a variety of "goodies" that are not
absolutely essential to Guide's operation,  but can be very helpful.

   If Guide detects that the second Guide CD is in the drive,  clicking
on "Extras... Install to Hard Drive" will bring up a very different list
from the one you got for the first Guide CD.  However,  as before,  you
can select and de-select items from that list,  right up to the point of
installing all 660 MBytes or so of data from the second Guide CD.  (Do
this for both CDs,  and you'll add about 1.3 GBytes to your hard drive.)
