BIOS image for the MSI H61M-E23 (B3) motherboard, stored in a RAR archive, with a 4MB flash capacity stated in the name. The H61 refers to the Intel chipset, and B3 denotes the later chipset stepping. A dump like this is used to reprogram the SPI chip with an external programmer when the board fails to POST after a corrupted update. Back up the existing chip before writing, and verify the image is exactly 4 MB and that the chip model matches.
