Small firmware archive tagged HCL Z24, apparently for an HCL desktop or all-in-one board identified only by the Z24 code. No revision, chip type or version appears in the name, so check the 663 KB package contents before using it. Files like this are used to recover a system with no POST by reprogramming the BIOS chip with an external programmer. Confirm that the board markings match, save a full read of the existing chip, and make sure the extracted image is exactly the size of the flash part.
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 @afsbiosfree. Enginerys does not host this file.
