BIOS for an HP system built on the MSI MS-7557 motherboard, version 2.0, packed in a 2.89 MB zip. MSI builds OEM boards for HP desktops and all-in-ones, and MS- numbers are printed on the PCB. The name does not give the flash chip type or capacity. Use the image to recover a board with corrupt firmware, written with a programmer or the vendor flashing tool. Back up the original contents first, check the MS number and revision, and confirm the file size fits the chip on your board.
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.
