BIOS dump for the ASUS X75VC notebook, taken from a board labelled X75VB main board revision 2.0, which indicates the two models share the same PCB. The flash chip named is an MX25L6445E, a Macronix 64 Mbit (8 MB) SPI device. The RAR archive contains the image for writing with an SPI programmer when the laptop fails to boot after a bad update. Verify the revision printed on the board, back up the existing chip contents before erasing, and make sure the image size equals the 8 MB capacity of the chip.
