How to upgrade switch flash

Unanswered Question

I have a Catalyst 3560 that I'm trying to upgrade the flash on. I found a document that outlined the process, which included using the CTRL-Break sequence to change the configuration register (entering into ROMmon mode). The document is specifically geared to cisco routers, so I was wondering if the process is the same for switches. The version of IOS that I'm running is 12.2(35)SE5 and trying to install a version that includes support for BGP. I have the new flash on the switch, but the switch boots to the old flash.

Any suggestions would be appreciated.

<font size="2">switch(config)#boot system flash:your_ios_image</font>

You can also set it through confreg in rommon, but the above command is easier.

Hope that helps.
