Chapter 3 Installing the Router
Using Flash Memory Cards in the RP
When you enter the
reload
command, the specified file (
new.image
) on the Flash
memory card inserted in PCMCIA slot 0 is used to boot the system.
If one of the following software configuration register settings were specified in
the preceding example, the system would behave accordingly:
•
0x2000—If the network boot fails, the system boots a default Cisco IOS
software image from a Flash memory card.
•
0x0100—The system ignores the Break function.
•
0x0101—The system boots the default image (the first image found) from the
onboard Flash memory SIMM on the RP. This setting also tells the system
that it should
not
reset the Break disable function, nor should it check for a
default filename for booting over the network.
•
0x0002—The system looks in the Flash memory SIMM on the RP for a
default Cisco IOS software image.
•
0x0102—The system disables the Break function and checks for a default
TFTP server filename. If the network boot operation fails, the system boots
from a Flash memory card.
Flash Memory Console Commands
To determine whether the present working device you are accessing is the onboard
Flash SIMM on the RP or a PCMCIA Flash memory card in a slot on the RP, enter
the
pwd
command at the privileged EXEC mode prompt on the system console as
follows:
Router#
pwd
slot0:
Router#
In this example, the present working device you are accessing is on a PCMCIA
Flash memory card inserted in slot 0 of the RP.
To change from one type of Flash memory device access to another, enter the
cd
device-name
command, where
device-name
can be
slot0:
,
slot1:
, or
bootflash:
.
Sample uses of the
cd
command include:
Router#
cd slot1:
Router#
pwd
