Memory
or
other
speed
and
feature
enhancements
are
seamlessly
absorbed
by
the
U
‐
Boot
firmware,
giving
a
consistent
look
and
feel
to
the
operating
system
and
the
user
application
as
the
GEIP
hardware
models
advance.
This
allows
the
constant
use
of
latest
technology
in
required
areas
without
system
impact.
Where
particular
operating
systems
define
the
use
of
alternate
boot
methods
(e.g.
VxWorks
BootROMs),
the
U
‐
Boot
firmware
technology
is
absorbed
into
such
boot
methodology.
8.4 Background Condition Screening
BCS
supplements
the
BIT
initialization
test
coverage
with
further
health
screening
that
can
co
‐
exist
with
a
standard
COTS
Operating
System.
In
contrast
to
a
traditional
BIT
‐
style
test,
the
intensity
and
coverage
of
which
makes
it
destructive
to
operating
systems,
the
configurable
BCS
package
allows
functions
such
as
periodic
check
‐
summing,
memory
scrubbing,
and
others
to
be
tailored
for
operation
alongside
the
application
in
on
‐
line
conditions.
Results
are
stored
in
Flash
in
the
same
format
as
BIT
results.
Code
is
available
for
reading
out
BIT/BCS
results
under
LynxOS
and
VxWorks.
