Using Flash PC Cards

Note An MS-DOS formatted ATA Flash PC card or linear Flash PC card can be accessed successfully

(including the dir command) with the Catalyst and IOS operating systems but will not boot from

ROMMON.

Note The 16-MB MEM-C6K-FLC16M(=) and 24-MB MEM-C6K-FLC24M(=) linear Flash PC cards are

formatted for the Catalyst 6500 series supervisor engines and are ready to use.

The MEM-C6K-ATA-1-64M= and 64-MB MEM-C6K-FLC64M(=) Flash PC cards are not formatted. You

must format these cards (see on page 7 for a description of the format command). When you enter the dir

disk0: or dir slot0: commands, an unformatted Flash PC card returns a “bad device block info” or “invalid

magic number” error message.

Note Supervisor Engine 1 and Supervisor Engine 2 do not support the same Flash PC card format. To use a

Flash PC card with Supervisor Engine 2, you must format the card with Supervisor Engine 2. To use a

Flash PC card with Supervisor Engine 1, you must format the card with Supervisor Engine 1.

the Flash PC cards. To perform specific tasks, use these commands either alone or combined with other

commands. For example, to copy a file from a TFTP server to a Flash PC card, set the BOOT

environment variable so that the system will boot from this new image and then verify the boot sequence

as shown in the following steps:

squeeze, show flash devices, show flash, and verify.

accessed through slot0:. The following procedure uses slot0:.
