Working BIOS dump for an HP laptop board with code name Hedwig92, board number 6050A3108001-MB-A01, revision A1. The 6050A numbering follows the Inventec pattern used on many HP notebook mainboards. The 7.51 MB RAR is marked as working, meaning it was reportedly tested on a live board. Use it to reflash the SPI BIOS chip when the laptop is dead or stuck, but first read and save the original contents, and verify the board number and A01 revision printed on the PCB match exactly.
