BIOS archive for the Acer TravelMate P453, platform BA50, board revision 2.0. The 4.60 MB RAR is meant for restoring the SPI flash of a board that fails to start or loops after a bad update. Extract it and confirm the image size matches the chip fitted to the board. Since BA50 boards came in more than one revision, check that the PCB is marked rev 2.0 before writing. Always read and save the original chip first, keeping the serial and system data it holds.
