BIOS image for the Acer Aspire 4736Z, with the name also carrying KALGO, which appears to be the internal platform or board code used for this model. The file has no extension and is 1.00 MB, matching an 8 Mbit SPI flash chip. Technicians write such a dump to the BIOS chip with a programmer like a CH341A when a laptop is dead or stuck after a failed update. Read and save the original chip contents first, and confirm the board code printed on the PCB matches before flashing.
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 @ComputerBIOSBinFile. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
