i found a solution for my problem :
i have to flash my main board bios any version but it must be 4.092 MB not more than that because the bios chip size is 4MB .
i flashed DH67CL bios and its working now with some features missing because its not the same board
so please if anyone have DH67BL mainboard can you just save your bios and send it to me it will fix the problem for me
many thanks in advance
