BIOS image for the ECS EliteGroup P55H-A desktop motherboard, version 1.0 of the board, sized for a 1 MB flash chip according to the name, packed in a 1.34 MB RAR. P55 points to the Intel P55 chipset in the model name. Extract the image and program it into the board's SPI flash with a programmer to revive a board left dead by a bad flash. Read and keep the original chip contents first, and check that the chip is 1 MB so the image will fit exactly.
