Small firmware read for the Lenovo IdeaPad Z500 on the LA-9061P board, which follows the Compal numbering pattern even though the name also mentions Wistron. At 56 KB and labelled an io read, it is likely a dump taken from the EC/keyboard-controller or IO board chip rather than the main BIOS. Such reads help restore an embedded controller that corrupted and blocks power-on or charging. Confirm which chip it came from, check its size against the target device and back up your own chip before writing.
