Tested BIOS for the Acer Aspire E1-476G on Quanta board DAZ8VRMB8E0 revision E, a 4.99 MB RAR. Quanta uses DA-prefixed board codes ending in MBxx0, printed on the PCB with the revision letter, so match both before flashing. The tested status suggests the dump has been confirmed working, though verify it still. Program it into the SPI flash with an external programmer when the laptop has no display or a corrupt BIOS, after saving the original chip contents and checking the image size.
