For example, the filename formation process may yield a range of typical
filenames like the following:
cisco2-grp
.
.
.
cisco17-grp
The system uses one of the filenames in this range to boot a default system image
stored on a network TFTP server.
If a bootable Cisco IOS software image exists in a flash memory card inserted in
slot 0 or slot 1, the software configuration register boot field setting is overridden.
The system boots from the image in the flash memory card, rather than from a
network TFTP image (that is, from a computed filename in the range from
cisco2-grp through cisco17-grp on the GRP and cisco2-prp through cisco17-prp
on the PRP).
Use the following procedure to change software configuration register settings
while running system software.
Enter the enable command and password (if prompted).
