[Request] Intel DQ77KB motherboard BIOS supervisor password reset

[falconhk2007]

I am new here, can anyone tell me if it is possible to reset the BIOS supervisor password by reflashing with modification to the BIOS image files?

I know there is jumper cap shorting pin 2-3 to get into configuration/maintenance page for reset.  But I don't know why my motherboard halts at Intel Logo page and cannot access the maintenance page for password reset.

By removing the jumper cap, I can upgrade and downgrade the BIOS version.  The password is persistent and still here even CMOS battery removal.

I have dumped the two chips (8M and 4M) image into files using the external EEPROM programmer (CH341A).  Just wonder if anyone can help to remove the supervisor password.  I can upload the two image files if necessary.

Thanks.
