Cisco Systems CISCO7201 Manual De Usuario

This appendix describes installation prerequisites you should observe before you can use the 
CompactFlash Disk in your system, and includes the following sections:

CompactFlash Disks are designed with flash technology, a nonvolatile storage solution that does not 
require a battery to retain data indefinitely. CompactFlash Disks provide complete PCMCIA-ATA 
functionality and compatibility as defined by the CompactFlash Association in their CF+ and 
CompactFlash Specification, revision 1.4.

The CompactFlash Disk is more flexible than linear flash memory because the CompactFlash Disk has 
controller circuitry that allows it to emulate a hard disk and automatically maps out bad blocks and 
performs automatic block erasure. Further, the CompactFlash Disk provides the capability to allocate 
noncontiguous sectors, which eliminates the need for the squeeze command (previously required with 
linear flash memory cards).

The CompactFlash Disk provides increased flash-based memory space—256 MB—for storage of system 
configuration files, Cisco IOS software images, and other types of system-related files.
