BIOS ROM for the Acer Aspire 4920, built on what the name calls a 965 platform, most likely the Intel 965 mobile chipset. It is marked working and labelled LTD version 1.20. The 1.00 MB image is sized for an 8 Mbit flash chip on the motherboard. It is useful for restoring a board that powers on without picture after a bad flash. Always dump the original chip with your programmer before writing. Compare the chip capacity, and confirm the board fits the 4920 series before using the file.
