ASUS 230IC BIOS for the DDR4 version of the board, revision 4.0, labeled as working, in a 6.39 MB RAR. The name likely refers to the V230IC all-in-one, but only the 230IC designation is stated. Firmware like this restores an SPI flash chip that has become corrupted, using an external programmer. Because other revisions and memory variants of this model have separate images, confirm revision 4.0 and DDR4 support on the actual board, back up the original chip, and check that the image size fits the flash.
