              33.8 KB? Not a very good job
              Try again (harder).

                  Interesting thing that i noted. If i desolder BIOS and put in programmer it reads just fine.
                  But if i try to read BIOS directly from mother board with clamps (also i checked and clamps are making a good contact with all 8 pins) it reads wrong like the file that i sent you first time.

                  Could it be that BIOS is ok but something is "killing" it and because of that i get false reading?

                      The same problem. When i pres power button the pwr led just flash once.
                      (also 3v3 is present only when the pwr led flashes once)
