Trouble after bootloader

Hello, i have a problem with an 328 after loading a new bootloader. What i have done: 1. i have a mikroelektronika dev board, used it to program the bootloader from version 0022, set the lockbits. 2. inserted the newly written chip into a arduino duemilanove with a ftdi and tried to write the blink sketch. I get the content mismatch error. With the chip that came preprogramed with the arduino duemilanove it works, with the written chip from me i does not work.

Shouldn't it be open source? Now if i try at home to make a arduino chip for a project i get a error.

found the error, the fuse bits were set wrong. Now i still get a error if i want to write a sketch to the chip via RX and TX. I bought and i tight RX to TX from the chip and TX to RX from the chip, DTR to the reset pin. I get a out of sync. If i put the chip in the duemilanove i can write to it. Any one got an idea?
