BIOS dump for the ASUS Eee PC 1005PX netbook, and the name identifies the flash device as an SST25VF040B, a 4 Mbit SPI chip. That matches the 512 KB size of the binary exactly. When the netbook stays dead with fans spinning, technicians read and rewrite this chip with a programmer such as a CH341A, selecting the SST25VF040B in the software. Save the original read before erasing, check the chip number on the board, and keep in mind that some SST parts need write protection cleared first.
