BIOS image for the Acer Aspire 4230 laptop, a 2.00 MB binary for a 16 Mbit SPI flash chip. The name lists no board number or revision. Technicians write such dumps with a CH341A or similar programmer to bring back boards that do not POST after firmware corruption. Acer laptops of this era used boards from different makers, so look up the motherboard number on the PCB and make sure it fits this model. Back up the current chip contents, which may hold system-specific data, before writing the new image.
