BIOS for the ESONIC H61DA1 desktop motherboard, an H61 chipset board, made for a Winbond W25Q32V flash chip with 4 MB capacity, packed as a 2.58 MB RAR. Technicians flash this image with a CH341A or similar programmer when the board shows no display or fails to boot because of corrupted firmware. Read and keep a copy of the original chip before erasing it, verify the chip marking is W25Q32, and confirm the extracted image size is 4 MB before writing and verifying.
