BIOS image for a J&W PH61A-USB3 desktop motherboard, an H61-class board, marked as tested OK. The 2.48 MB RAR holds the dump ready for programming. It is meant for recovering a board that fails to POST after a bad update or corrupted SPI flash. Unpack it, read the chip on the board with a programmer such as a CH341A and keep that backup, confirm the motherboard model printed on the PCB is the same, and check the dump size matches the flash capacity before writing.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
