BIOS archive for an HP board with part number 6050A2977701-MB-A03, revision A3, about 12.4 MB compressed. The 6050Axxxxxxx format is the PCB number style used by Inventec and also seen on Foxconn-built boards, and the -MB-A0x suffix gives the board revision. Check this number on the PCB before flashing. Unpack the archive to see which images it holds, match each to its chip by size, and keep a full backup of the original flash contents.
