Tested BIOS binary for a Huawei laptop built on the Quanta DAH98MB1AA0 motherboard, revision A. The image is 8 MB, matching a 64 Mbit SPI flash chip. The DA-prefixed code follows Quanta's ODM numbering, so the laptop model itself is not stated; rely on the board number and revision printed on the PCB. A raw dump like this is written with a CH341A or similar SPI programmer when the firmware is corrupted. Read and store the factory contents first and verify after programming.
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 @generalbios. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
