Working BIOS dump for the ASRock AB350M-HDV motherboard at revision 1.04, an AM4 board, in a 16.7 MB rar archive. The working label in the name suggests it was read from a functioning board, which makes it suitable for recovering a unit with corrupted firmware. Write it to the SPI flash with an external programmer such as a CH341A, after checking that the image size matches the chip capacity. Verify the 1.04 revision silkscreened on the PCB and keep a backup of the original chip before flashing.
