Customizing
the
device
driver
configuration
settings
Microsoft
Windows
Me
and
Windows
2000
Professional
have
two
device-driver
configuration
parameters:
Auto
Insert
Notify
and
DMA.
The
Auto
Insert
Notify
parameter
enables
the
computer
to
start
playing
or
accessing
the
disc
automatically
after
being
inserted
in
the
drive.
The
DMA
parameter
improves
the
computer
performance
by
having
the
computer
DMA
controller
handle
data
transfers
from
the
CD
to
memory,
freeing
the
computer’s
microprocessor
to
perform
more
important
tasks.
For
example,
activating
DMA
might
make
movies
and
games
run
more
smoothly
because
the
microprocessor
is
allocating
more
processing
time
to
video.

DMA
