Firmware dump for an ASUS CS-B COM SI board, revision 1.03, intended for a Winbond W25Q128BV flash chip, which holds 16 MB, stored in a 6.62 MB RAR archive. ASUS uses this type of board in business desktop systems. The image is written back with an SPI programmer such as a CH341A when the board fails to post or the firmware is damaged. Confirm the revision on the PCB and the chip marking, read the original chip before erasing, and make sure the extracted file size matches the 128 Mbit part.
