To create a boot medium to use in the internal
compact flash only, select the check box.
On an external compact flash or USB storage
device only, creates a snapshot for use as the
primary boot medium.
Use this feature to replace the medium in the
internal compact flash slot or to replicate it for
use in another Services Router. This process also
partitions the boot medium.
NOTE: After the boot device is created as an
internal compact flash, it can operate only in an
internal compact flash slot.

kilobytes.
The data partition is mounted on /data. This
space is not used by the router, and can be used
for extra storage.
This selection also partitions the boot medium.

value is one-third of the physical memory on a
boot medium larger than 128,000 KB, or 0 KB

device, see “Configuring a Boot Device to
Receive Software Failure Memory
Snapshots” on page 190.
