Acer Extensa 4630Z BIOS dump, 2.00 MB binary, marked ok2 in the name, which indicates a second copy reported as working. It sits alongside other 4630Z images, including a 1 MB version, so compare sizes against the flash chip actually fitted before choosing one. Raw dumps like this are written with an SPI programmer to revive a dead or bricked board. Always read and archive the original chip contents first, and check the board number on the PCB, because firmware from a different board revision may not boot.
