Chapter 1 CompactFlash Disk, Flash Disk, and Flash Memory Card Information
Working with a CompactFlash Disk, Flash Disk, or Flash Memory Card
The CompactFlash Disk, Flash Disk, or Flash memory cards, along with other locations in your system,
are defined as file systems, which are locations where you can store, use, or retrieve files and software
images. You can use a Flash Disk or Flash memory card in either one or both of the PC card slots in your
I/O controller, and you can use a CompactFlash Disk in the one CompactFlash Disk slot on the NPE-G1
or NPE-G2.
The CompactFlash Disk inserted into the CompactFlash Disk slot in the NPE-G1 or NPE-G2 is referred
to as the disk2: device. Flash Disks or PC cards inserted into slot0 and slot1 are referred to as the slot0:
and slot1: devices, respectively.
The following partial output of the show file systems command shows a sample system with a
Flash Disk—called disk0:—installed in PC card slot 0 and a linear Flash memory card—called
slot1:—installed in PC card slot 1:

Note The show file systems command displays all recognized file systems, even if they are not currently in
use. This is why the above display shows entries for both slot0: and disk1:, even though those devices
are not currently inserted into the PC card slots.
Table 1-4 lists the software commands, along with their most common command options, that you can
use with the Flash memory cards.
The following device names can be used with most of these commands:
• disk2: (CompactFlash Disk)
• disk0: and disk1: (Flash Disks)
• slot0: and slot1: (linear PC cards)
• bootflash: (onboard Flash memory)
• nvram: (onboard nonvolatile random-access memory)
• running-config (the running system configuration file)
• startup-config (the startup system configuration file)
• tftp: (a TFTP server to which you have access)
