Second copy of an ALi 3511 StarTrack firmware with the 10000500 identifier and lance label, but at 4.59 MB it is slightly smaller than its namesake, so contents may differ. Compare both archives before flashing. The image restores receivers built on the ALi 3511 platform, typically through a serial upgrade utility. Verify that the board chipset and hardware ID match, dump the current flash first if the tool allows, and never interrupt the write, since failure may require reprogramming the chip with an external programmer.
