Need help for 25q64 eeprom programming

[visp]

Hello,
I'm big trouble.
I would like to write a bios into the winbond 25q64 eeprom with FlashCat usb programmer.
I downloaded the original bios file, and write is ok, but doesn't switch on the laptop. And doesn't match the read bios file and write bios file size.
Can anybody help me?
I think base address is wrong, but I don't know.
I have asus g75vw laptop.
Connection:

The size of the Winbond chip is correct , The size of the bios itself is only 6MB whereas the chip is 8MB.
You may need to do a total erase of the chip first and then write your Bios file.
The read back will always differ as you are reading back 8MB instead of 6MB.
