BIOS image for a Positivo computer, model given as SIM 970M with the number 11611, packed in a 1.75 MB RAR archive. Positivo is a Brazilian manufacturer, and dumps like this are used to reprogram a corrupted SPI BIOS chip with an external programmer such as a CH341A. The meaning of 11611 is not stated, so verify it against the board markings. Back up the original chip before writing and confirm that the dump size equals the capacity of the flash chip.
