BIOS archive for the K42JR mainboard at revision 4.0, an ASUS model naming pattern, with the name noting a 25Q32 flash chip, a 32 Mbit (4 MB) SPI part from the 25-series family. Knowing the chip lets you select the correct device in programmer software before reading or writing. Verify that the board revision printed on the PCB is 4.0, read and save the original contents, and confirm the extracted image matches the 4 MB capacity, since a mismatched file will not program correctly.
