Firmware dump for a Positivo Sim notebook with board A14HVOX revision 4.0, noted as a 4MB BIOS, in a 1.80 MB RAR archive. The 4MB figure indicates the image is intended for a 4 MB (32 Mbit) SPI flash chip, so check the chip marking before programming. Technicians use such an image to revive a unit with corrupted firmware through a programmer clipped onto the chip. Verify the board revision on the PCB matches 4.0, and keep a backup of the original contents in case settings or serial data need restoring.
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.
