BIOS firmware for the Acer Cloudbook A01-431 on mainboard 6050A2767601-MB-A01, stored in a 3.47 MB RAR archive. The 6050A numbering with the MB-A01 suffix is the Inventec scheme, so Inventec is the ODM and A01 the board revision. This dump serves recovery of a board with corrupted firmware, written to the SPI flash using an external programmer. Read the original chip first to keep any unique data, then confirm the image size matches the chip and the PCB number matches.
