Only you can try it take bios chip from spare motherboard put it into sony see if it boots from floppy usb e.c.t hot swap chip back to your bricked one then flash with original sony bios.
I was also wondering after i get it working can i just use the bios from asus for the board instead of sony cause asus has newer ones than sony
i make a mode bios (new F7) for GA-EP45-UD3LR with SLIC 2.1 DELL, from post 1723 everything works fine. thanks
all i did was recommend the flash tool, not responsible for your modded bios (which you don't even know to be working) and your flashing method. sorry you book's not working.
is there any way of verifying a bios will work besides actually flashing it and trying to activate? Because I made my own but am not sure how to make sure it's good.
