Firmware dump labelled as read from an Acer Aspire 5520, stored as a 1.00 MB binary. The read tag suggests it was pulled directly from the flash chip with a programmer rather than extracted from a vendor update package. No board number or BIOS version appears in the name. Such an image can restore a laptop that fails to POST after a bad flash. It must go onto a chip of matching 8 Mbit capacity, and the existing chip should be backed up before it is erased.
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 @biosbigarchives. Enginerys does not host this file.
