Correct boot system slot0 syntax

Unanswered Question
Jul 13th, 2009

We have a 4510 with two supervisors V modules, both with a memory card. In order to boot off that card, is the syntax:

"boot system slot0:xxx"

or is it

"boot system flash slot0:xxx"

Hi Collin,

Are you sure its "disk0" and not "slot0" on a 4510 with IOS? Either way, you have to include the word "flash" .

A dir /all will tell you the exact file system. I have not seen 'slot' in a while, most now use disk (I believe it's dependent of the platform).

Hi Collin,

The dir /all only returns the bootflash files, nothing in the slot0.

dir disk returns "unrecognized command", while dir slot0: returns the files on the memory card.

The document was only valid for 4500 using CAT OS, and we are using IOS.

But I think you've answered the major question, which is that I have to include "flash" in the boot system statement.

Hi Collin,

I used the command line "boot system flash slot0:xxxx.bin" and everything came up nominally. thanks for the help.
