Compressed BIOS image tied to the IBL50 project on the Compal LA-3611P mainboard, packed into a 631 KB RAR. IBL50 is the Compal internal platform name used alongside the LA board code. The small size suggests an older-generation flash chip, so check the capacity of the chip on your board before writing. Use it to restore a laptop that stays black after a failed update by programming the SPI or firmware hub chip directly, and save the existing contents first in case the image differs.
