Hi all, I have a Cat6500 x6k-sup2-2ge running an IOS software.

My problem is that I'm stuck in rommon mode after the IOS upgrade. Now I have A PCMCIA and I want to boot a new IOS from the PCMCIA.

I cannot format the PCMCIA from the rommon mode.

How can I format the PCMCIA? The only way is format from a target Catatalyst switch?

All these because I have an error about invalid magic number when I insert the PCMCIA card into the Supervisor2 slot in rommon mode.

Please I need your help,

Thanks in advance.

Hi David,

Take the PCMCIA card to another sup2 and format it. Then copy the image from that device or from a FTP Server to the PCMCIA card.

Is there an image on the supervisors 'sup-bootflash: ?

To check see below CLI:

rommon 1 > dev

Devices in device table:

id name

bootflash: boot flash

disk0: PCMCIA Disk 0

Then list the contents of bootflash:

rommon 2 > dir bootflash:


rommon 3 > boot bootflash:image name

After the image is successfully loaded you can format PCMCIA card and copy the image you need.

For this problem your options are pretty limited.

Hope this helps.
