Compressed BIOS firmware package for a Positivo machine identified as POS-PQ45AU, with revision 1.07 given in the name. The archive is about 1.76 MB and should contain a flash image meant to be written straight to the board's SPI chip. Technicians use dumps like this to recover units that are dead, stuck at a black screen, or corrupted after a failed update. Compare the PCB silkscreen with the model code first, read the original chip as a backup, and make sure the image size matches the flash capacity.
