I have Lenovo Z400 and I messed up its BIOS Settings after I accidentally saved the Settings I just set when I have Modded it and now, It wont boot anymore but I bought the Mini Programmer, CH341A to be Exact, as well as the SOIC 8 Test Clip , But the problem now is I dont know what to do because this model has 2 BIOS CHIPS, (Both Winbond, 25Q16CVSIG and 25Q32VBSIG) and when I tried to connect it with the SOIC 8 Plugged from the CH341A that is connected on my sister's laptop, It wont detect the correct details / version of the BIOS Chip and when I click the "Read" Button, it will read it, but when I tried to program it with its default BIOS file, I get the error "chip with the contents are in dissagreement"
Please help me

How can I make dump? is it the "Save" option from the program ?

1. Check the programmer connection
2. first use Detect
