Firmware for the IPISB-CH2 board, prepared for a Winbond W25Q32 flash, the 4 MB SPI chip named in the archive. The RAR is about 2.18 MB, and the name gives no system model or BIOS version. A file like this is used to reprogram a corrupted BIOS chip with a CH341A or similar programmer, either in-circuit with a clip or after desoldering. Check that your board is the CH2 variant and carries a 4 MB chip, and dump the existing contents before erasing, so you can go back if needed.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
