BIOS package for the HP 1000 laptop line, 414 KB as a RAR archive, tagged 1M and OK. The 1M marking points to the small 1 MB flash on some boards in this family, as distinct from the 4M variant, and OK signals a dump reported as working. Such small chips often hold the EC firmware or a shared BIOS/EC image. Extract it, check the size against the chip capacity, read and save the original contents with your programmer, and confirm the board revision before writing.
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.
