Hey guys,

I was updating the IOS on my 2900 series switch. In retrospect i probably shouldn't have.... but oh well!  Bottom line is that in the process I entered in the wrong name for the boot image.  I went through the process on this page: but baulked on step 13.  The IOS I had was not in tar format and my tftp server was not functioning properly so I figured I would stop the process there and figure out the tftp issue- that was my first novice mistake!  I then figured that since i did not save the changes i made to the the config the switch would be fine- Second novice mistake!  Now all I get at the prompt is a Switch: .   I used copy xmodem and pushed up the correct .bin but now i can not get into EXEC Privilege mode to make the changes to the set_bs area because I cannot enter ENABLE.  Any assistance would be most helpful.

Well it sounds like you punished yourself enough.  Now you need to get the right image and follow these instructions:

Definitely follow the instructions for speeding the transmission too.
