router problem

[smart.hunter.811]

i was doing some hands-on labs and typed in "boot system tftp c2600-i-mz.123-9" to boot my router from a
tftp server and when my router restarted it said that the file was to large to load into memory and my router kept restarting at that point as it wasnt able to load the IOS from my tftp server. i then like a dummy booted my router into ROM and typed in "confreg 0x2102" or "2101" and now when my router starts up i get all these weird looking characters.

i can no longer boot my 2911 router. im going to do some google searches while im at work but any help would be appreciated.

Normally the "weird characters" on the console port while starting up are a console port/terminal emulator speed or parity mismatch.  Does the "junk display" appear to come in blocks like a normal startup with console attached?

Default would have been 9600-no parity-1 stop bit (verify your emulator); but this can have been changed on the router if somebody had tried to XMODEM an image to it at higher speeds.
