BIOS dump for the Toshiba B40-A laptop, board MR10F with number 6050A2578201 and MB revision A02; the asli suffix is Indonesian for original, suggesting an unmodified read. Boards numbered 6050Axxxxxxx follow the Inventec numbering pattern, so the ODM is Inventec rather than Toshiba itself. Technicians program such an image into the SPI flash chip with a hardware programmer to recover a dead or bricked board. Check that the PCB number and A02 revision match, back up the current chip, and confirm the image size agrees with the flash capacity.
