Archive labelled as BIOS firmware for the Acer TravelMate 3260 with ZR1 model code. The RAR is only 290 bytes, far too small to hold a BIOS image, so it is most likely empty, a placeholder or broken and should not be trusted. No board number is given in the name. Before any repair, look for a complete dump whose size matches the SPI flash chip on the board. Always read and save the original chip contents with a programmer before writing anything new.
