About this board

Files for the Sony SVF143A1QT HKC motherboard, board number DA0HKCMB6D0.

The board was manufactured by Quanta for Sony. Quanta board numbers start with DA and include MB, so you can confirm it on the PCB silkscreen. This listing is for revision 4.7; another revision of the same board can need a different file.

Files usually needed for this board

BIOS (full SPI chip dump, .bin)
EC / KBC firmware, if the board uses a separate EC chip
Schematic (PDF)
Boardview (.brd / .bdv / .cad)

Typical reasons to reflash: no power or no display after a failed BIOS update, a BIOS/supervisor password lock, or a corrupted Intel ME region.

Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.

If you have a working file for this board, please share it below. More files: search DA0HKCMB6D0 in File Finder.
