Options for the create_cf Command
Note: Use the --image[1|2]option to save the image that is currently in
RAM into a specific image area, without reformatting the partitions that
contain the other image.
The following table provides more information about the create_cf
command options, which you can view from the Linux command line by
entering the name of the command.
Table B-1: Options for the create_cf command
Option Description
none Not recommended. Checks if a boot image is already on the
device. If no image is on the device (as would be true for a
newly installed removable flash on a PCMCIA card) and if no
image is specified, runs --doformat and installs the image in
image1. If multiple images are on the device, and no image is
specified, presents a choice of images for the user to choose
from, and then writes the image from RAM into the specified
image area. In either case, restores the factory default
configuration
-d device Creates the image on the specified device. The default device
is /dev/hda (the removable flash memory). Make sure the
filesystem is not mounted.
Use the -d device option if you want to create the image in
another location, such as on an installed compact flash
PCMCIA card. (The device names for PCMCIA cards are
determined by the number of the card slot where the card is
installed, either /dev/hdc (PCMCIA slot 1) or /dev/hde
(PCMCIA slot 2).
--factory_default Creates the image using factory default configuration files. By
default, if this option is not entered, the configuration from the
current partition is used, if valid. For more details, see “How
Configuration Changes Are Handled” on page 59.
--doformat Rebuilds the partitions, erasing their contents.
Creates the image as image1.
