BIOS ROM for the Acer Extensa 5230E on an Intel Mobile 4 Series chipset, marked working at version 1.36. Its 2.00 MB size calls for a 16 Mbit SPI flash chip. Writing it to a smaller chip will fail. Use a programmer such as CH341A or RT809H, and read and store the factory contents first, because they can contain unit-specific data. Confirm the board matches this Extensa model, then erase, write and verify the chip.
