The device includes the :. type dir bootflash: to see the bootflash info. Does the 5350 have a pcmcia slot with anthing in it? It would be referenced as slot0: or disk0: depending on the flash type. See if there is a boot system command in the old config. That will tell you if the system was loading from somewhere else that was bigger than bootflash.

Hi,

The timeout indicates an error when using the terminal emulator.If you're using hyper terminal, make sure you're using the right protocol. If you specified the "-y" then you should specify the Ymodem protocol after choosing the transfer and send from the menu. I don't think you have any data rate speed problem between the router console port and the PC.
