HP Omen 15 firmware set for Quanta board DAG3DCMBCC0, revision C, combining the BIOS with EC and KBEC images in a 7.20 MB RAR archive. DA-prefixed codes like this are Quanta motherboard numbers, and HP gaming models frequently use them. The BIOS is written to the SPI flash and the EC or KBEC file to the embedded controller, which together govern power sequencing, battery charging and keyboard. Back up both original chips before programming, and make sure the revision printed on the board is C.
