BIOS dump for the Acer Extensa 4630Z, an Intel-based model, with the board code JALA0 given in the name. Packed as an 864 KB RAR, it is used to restore the SPI firmware chip when the notebook is dead or stuck after a failed update. JALA0 style codes belong to Compal project naming, so look for the same code on the PCB before use. Read and keep the existing chip contents first, and confirm the image size fits the installed flash.
