I am attempting to repair a bricked Asus X53SV notebook (Asus K53SV board) by reflashing with flashrom from a Raspberry Pi. I've got it all hooked up and flashrom recognizes and reads the chip. However, I cannot determine what type of file the BIOS update is that I downloaded from Asus support site. The update I'm using is K53SVAS.315 for Aptio's Easy Flash. How can I extract the raw BIOS from this file?
After further research, I've determined that the download offered by Asus is not a complete BIOS image file. It cannot be used to reflash the EEPROM directly as it does not contain all of the information required. The built in Easy Flash utility uses this file to update only a portion of the EEPROM. The only officially supported method of repairing a bricked Asus notebook is to send it back to Asus.
