BIOS firmware for an HP 15 notebook on Inventec board 6050A2547701-MB-A02, with 15SBGU named as the platform code. The 3.9 MB archive likely holds an SPI flash image used to recover a laptop that will not post or boot after a corrupted update. Inventec's 6050A numbering identifies the board and the A02 revision, which should be checked on the PCB. Read and keep a copy of the original chip before programming, and verify the image size matches the flash capacity.
