Firmware for the Megaware Mega Netbook 6658, version 1.3, supplied as a 708 KB RAR archive. The name lists no chipset or board revision, so compare 6658 with the number on the netbook board. Technicians use such images to rewrite a corrupted BIOS chip with an external programmer when the unit powers on without display. Netbook boards often use small SPI or LPC flash chips, so check the image size against the chip, and always read and keep the original contents first.
