Just program eeprom 12f6XX

[1Steveo]

I have a chip that was program with the data being protected, But the eeprom has some data that will change once I power it up. (default value)

I would like to try to Modify some componants to see if they will better suite my needs, but Im sure the default data will change.

I see no way to just program the eprom with "ICPROG" without erasing the chip!

Thanks

Do you mean save the eeprom data memory but rewrite the flash program memory?
Can't you just read the eeprom data, save it to a file, and them load it back in with the new flash code? This should work unless the chip is code protected; then you are in the realm of hacking and I can't help you there.

Do what I did... Get a PicKit2 programmer.. I can program the EEprom and normal flash areas completely independently of each other using the stock software.

IcProg is a great free utility, but does have limitations.

Try WinPic. This appears to be able to program the EEPROM separately.
