What model is your programmer and software version. What is the chip part number that you backed up, the file doesn`t look right, it`s like the 1MB USB-C firmware saved as 32MB ? . If you have used the programmers Auto-detect setting choose the chip manually instead, and look for the chip in the support list

im using ch431a to read , software asprogrammer v2.1.0.13, the chip is winbond 25Q80DV... i read it manually with 256mb setting

Ah, that`s where you`ve gone wrong. The 25Q80DV chip is 8 Mega bits - 8Mb = 1MB (Mega Byte) . The chip is 1MB and you chose a 256MB chip manually, so the programmer read it and padded it out. I hope you didn`t erase that chip. Leave it alone and look for the right one..

i did not erase it... what should i do?

[SMDFlea]

By choosing the chip manually you told the programmer that the 1MB bios chip is 32MB, when it isn`t. Find the 32MB chip ,choose Auto-detect.If it doesn`t recognise the chip by the part number that is on it then manually choose a different 32MB (256Mbit) chip in the list.

Find the chip with the number 256.

No, you`re getting mixed up. Find the chip in the red circle in the picture, tell us what part number is on it , and post some pictures of it.

That is the bios chip. It has no legs on it, the chip type is WSON8. You will not be able to read it if you only have a SOP8 clip,which is designed for chips with legs that stick out. If you can`t desolder the chip you could buy and use a WSON8 pogo adapter.
