arduino fuse bits for mega 328P

I have burned the optiboot for mega 328p using an ISP burner. my problem is i have set the fuse bits according to the make file given, but i cannot upload any sketch to the board. all i can see is the rx pin blinking and there is no response from the MCU. i know that the 328 p can only support utp 8 mhz, but i have already with me a 328p with bootloader in it (bought one) which works fine. is there any other method for buring bootloader to 328p? or is it the problem of the fuse bits?

Hfuse : DE
L fuse : FF

Have you verified that the flash was successful? You may also be clocking out the data too fast.
