BIOS image collection for the HCL Z24, archived in RAR format at 709 KB. No mainboard number, revision or chip information is included in the name. Repair technicians use such files to restore firmware on machines with a corrupted BIOS, typically by clipping or desoldering the SPI flash and writing it with a CH341A or similar programmer. Extract with WinRAR or 7-Zip, confirm that the file length matches the chip capacity, and dump the existing contents as a backup before programming.
