BIOS for the HP Compaq 6530s notebook, labelled with board number 60502161001-MB-A04, which appears to be the Inventec 6050A2161001 mainboard at revision A04 written without the letter. The 1.16 MB RAR is intended for writing to the SPI flash with an external programmer to recover a board with corrupted firmware or no boot. Read and store the original chip first, as HP keeps serial and system data in it. Verify the board number on the PCB and the flash capacity before programming.
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.
