Following
are
some of
the
most useful bootstrap
commands
The
command
prints
summary
of the bootstrap
commands
The
command
causes the
bootstrap
program
to reinitialize
the
hardware
and
clear
the contents
of memory
The
command
runs
stack
trace
on
system
hardware
The
conmand
with no argument boots the default software
from
ROM
assuming
there are
no jumpers
in
the boot
field
portion
of the configuration
register
You
can include an argument
filename to specify file to
be
booted
over the
network
using
Trivial
File Transfer
Protocol
TFTP
You
can also include
second
argument host
which
is
the Internet
address
or
name
of
particular
host
on
the
network
The command
runs various diagnostic tests but
is
not
recommended

Memory test
Probe ID/memory
space
By
default
the
memory
test
examines
onboard memory
on the processor
and
memory cards
You
can
test
NYRAM
on
the
CSC-ENVM
by
supplying
starting
and
ending
addresses
as
described
in
Table
4-1 The
test
is
destructive
to
data
in
NVRAM
The
CSC-MC
or Flash
memory
cannot
be
tested in this
way

Use the
Probe
I/O memory
space
test to
look
at
the
mapped
110 space
in the
main
memory
and
test
for
interface card responses
The
test starts at
address
2000000
You
can specify probe increments in
order
to
look for
specific
regions
The
test
uses the probe increments to
search
for registers that
can
be
read
from and
written
to See
