Working-marked BIOS image for the Acer Extensa 4630Z, 1.00 MB in size, where ok in the name suggests it was tested on a board. Its 1 MB size matches an 8 Mbit flash chip, unlike the 2 MB dumps for the same model, so it fits boards fitted with the smaller chip. Writing is done with an external programmer such as a CH341A clipped onto the SPI chip. Check the chip marking and capacity beforehand, since an image that does not match the chip will not fit, and back up the original data.
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.
