You can operate GEOS using one disk drive or two. If you are using an
REU, GEOS will treat it as Drive B. Adding or changing disk drives is
easily done by using the
Configure program.
Switching Disk Drives
On the deskTop, the disk drives and REU are
Drive A
represented by icons located on the right side
of the screen. The disk drive icon at the top of
the screen represents Drive
A; the one below it
is Drive
B (which also can represent an REU).
Drive B
You can switch disk drives simply by clicking
on the disk drive icon you need.
Many GEOS applications will read
a file in another disk drive. For ex-
ample, you could place the
geoSpell spell-checking program on a disk in
Drive A and
a group of geoWrite documents on a disk in the other disk
drive. When you open
geoSpell in Drive A, it will display a dialog box
listing documents you can spell-check on the current disk. This dialog box
will also enable you
to gain access to a list of documents in Drive B.
If you add or change a disk drive, you can use the CONFIGURE program
on the
deskTop to enable GEOS to recognize it. (This file is located on the
GEOS ADDT'L side of the program disk.) Afterwards, every time you boot
GEOS, the new disk drive will
be recognized.
