BIOS archive for an MSI Z490 desktop motherboard, listed as Z490-S01 with model code MS-7C98 and a 16MB flash size. MSI identifies its boards by MS-xxxx project numbers printed on the PCB, which is the safest way to confirm a match. The RAR is 23.1 MB, so it may include more than one image; extract and check it. Back up the existing SPI chip with a programmer before writing, and make sure the image is exactly 16 MB to suit the chip.
