CLEARING FLASH ON CISCO ROUTER 3102

I PURCHASED A CISCO 3102 ROUTER, 2500 SERIES WITH A 11.2 VER IOS. THE PROBLEM IS THAT I PURCHASED IT FROM EBAY AND THE ORIGINAL PASSWORD DENIES ME COMPLETE ACCESS. AFTER ATTEMPTING PASSWORD RECOVER USING VARIOUS BREAK SEQUENCES, I NOW HAVE A BUNCH OF CHARACTERS WHEN IT BOOTS FROM FLASH,AND AM STILL DID NOT GAIN ACCESS WHICH WOULD THEN ALLOW ME TO BOOT FROM ROMMON
SO THAT i CAN CLEAR THIS PASSWORD.

IF YOU ARE FAMILIAR WITH 3102 ROUTER AND KNOW HOW I CAN CLEAR THE NVRAM AND ENTER SETUP. PLEASE HELP P.S. IF I REMOVE THE ACTUAL FLASH MODULE WOULD THAT CLEAR IT, SO OF LIKE CLEARING CMOS ON A PC. JUST A THOUGHT....HELP HELP HELP
