Extensionless 1.00 MB firmware file labelled Acer 4315, most likely a raw dump of an 8 Mbit BIOS chip. Apart from the model, the name says nothing about the board number or version. Rename it with a BIN extension if your programmer software needs one. Compare it with other copies by checksum, and check the PCB before writing it. Flashing with an SPI programmer can recover a laptop with corrupted firmware, provided the original chip is backed up first.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
