Flashing BIOS with universal programmer(need help)
#1
Hello everyone reading this. 

I am trying to learn more about manually flashing a BIOS chip.




there are times that i can easily flash an BIOS chip which are for example provided as an .bin file from the motherboard manufacturer, and are the exact size and hex code looks almost similair.

but i find my self stubbing upon a different situation multiple times and not really sure how to solve it on my own.


in this case i have an Asus motherboard with the need to manually flash the BIOS chip with my Universal programmer. 

i would obtain a healthy bios firmware file, which is in a zip file, after extracting this BIOS file i would end up with the following file:

K72JkAS.204

the file is 2.048 KB

when i compare this extracted bios file to the one i just dumped directly from the BIOS chip, i end up with different size. to be exact 2x bigger

4.096 KB

.also the HEX code looks diffirent. 

i have uploaded both of those files maybe someoen can take a look at it and explain me how do i go about manualy flashing such BIOS

the file directly dumped from the BIOS chip:

the firmware file that i am trying to flash(which was downloaded directly from asus )

The links don't work for me, also could you give the model number for the Asus board or model of laptop?

maybe you have dual bios so you have to join 2 copy of the new bios files and then flash the 4mb file.

you can do it using the copy command in windows.
