Quanta board DAX8QIMB8B1, revision B, with firmware for both the SPI BIOS ROM and the EC ROM, marked OK, packed in RAR. Quanta uses the DA-prefixed number as its PCB identifier, and it appears on boards for many laptop brands. Having both images helps when a board is dead because of corrupted EC code as well as BIOS. Program each file to its correct chip. Back up both originals first and confirm the chip sizes match the images.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @bios_laptopomi. Enginerys does not host this file.

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 →
