BIOS firmware for the HP 255 laptop, board 6050A1501401 in revision MB-A02, with HP platform code TPN-1106. Packaged as a 4.28 MB RAR archive. The 6050Axxxxxxx numbering is the Inventec style used on many HP notebook mainboards. A technician uses this dump to reprogram the SPI flash chip when the laptop shows no display, keeps restarting, or has a corrupted BIOS. Confirm the 6050A number and A02 revision on the PCB, save the original chip contents, and match the image size to the flash chip.
