choice
to
run
a
DMA
controller
test
or

CMOS
validity
test.
DMA
controller
test:
This
test
is
a

read
and
write
tests
on
the
memory
address
registers

from
system
memory
and
an
″intelligent″
peripheral
device,
without
passing
through
the
microprocessor.
On
error,
the
AMIDiag
program
displays
the
register
number,
data
