Acer Aspire 4720 BIOS dump labelled as the HBM version, provided as a 1.00 MB raw binary file. The image is intended for direct writing to the motherboard SPI flash, a common fix when a notebook shows power but no image or keeps restarting because of corrupted firmware. Open it in a hex editor to check that it is not blank or filled with FF, and compare its size with your chip, which should be 8 Mbit. Read the existing chip twice and save the copy before erasing so you can roll back if needed.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @abgm_manutencao_bios. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
