BIOS dump described in the name as for the IdeaPad Flex 5 S, a Lenovo model, with board number 223073-1, stored as a 12.2 MB RAR. The brand field says Apple, which conflicts with the model name, so treat that tag with caution. The numeric dash-suffix format matches the Wistron board scheme. The name also contains the word WORLD, probably a source tag. Use it to reprogram the SPI flash on a dead board, after confirming the PCB number and backing up the existing chip.
