 It means blank check failed.So you can erase the chip more time than before and check the chip blank first.And then you can program it successfully.

 With the new soft, programming"s working ! but there"s still a problem : While programmed the eprom don"t match 100% to the original file : for example, for a 2048ko file i"ve got more than 30 differences... and the eprom doesn"t work. ( i tried with differents eproms and differents files).

 I tried to erase chips twice longer time... but it"s the same. I tried with about 10 differents 27c322 chips. I"ve got the same problem with HN27C4096G chips: <<Data compare result>>
>>Chip Addr.　Data-----Buffer Addr.　Data　
>> 00004000H　000AH　　 00008000H　 000EH
>> 00008000H　068FH　　 00010000H　 178FH
>> 00014000H　46B8H　　 00028000H　 4EB8H
>>Compare OK!
>> 3,08Sec
----------------------------!
For exemple here i"ve got 3 differences but the result is ok???

 It is compare and it is not verify. If it can complete compare, it will show OK.

 i noticed that with the new version it"s a little longer to program the eprom... but the final eprom doesn"t match at all with the original file (here, more than 20 differences).
I tried to read and save this eprom in a file, then i compared it with the original file in another soft (hex workshop), it finds this 20 differences... at final the checksum is bad, then the eprom doesn"t works.
