BIOS for the Acer Aspire 5745, board DAZR7MB16C0, HM55 chipset in the UMA version with integrated graphics only, packed as a 1.67 MB RAR. DA-prefixed board numbers follow Quanta numbering, and here ZR7 is the project code. Use it to reflash the SPI chip when the notebook does not POST. Do not use it on discrete-graphics boards. Check the board label, back up the original flash with a programmer, and make sure the image size matches the chip.
