BIOS firmware for the E11IS2 board in its Bangho-branded form, Bangho being an Argentine PC brand, compressed as a 575 KB RAR. Nothing else, such as revision, BIOS version or flash chip, is stated in the name, so examine the image after unpacking. Technicians load dumps like this into a programmer software and write them to the SPI chip to revive boards that will not POST. Keep a backup of the original chip, match the board code printed on the PCB, and confirm the image fits the chip size.
