Configure
the
new device.
If
you know how
to
configure
the
new device, continue with
SYSGEN.
If
you do not know how
to
configure
the
new device, check
the
IODEFAULT file
iodfault.pw.sys using
the
Editor
to
find
the
correct driver.
2.
Configure
the
device on
an
available
path
with like devices.

of
the
device is set correctly
to
match
the
configuration
in
SYSGEN.
7.
Power up
the
device
and
the
system. At
the
PDC
prompt,
access
the
PDC

menu.
Use
the
All
command
to
display all system configuration and card
path
information.
Or
you can bring
the
system up
to

IOMAP
to
check
