BIOS read from a board identified as SABA MB, WHL_4 VRAM, with number 18748-1, which follows Wistron's numbering pattern. WHL likely indicates Whiskey Lake, and the name marks the read as good. The 14.8 MB RAR suggests the archive may hold more than one image or a larger flash dump, so inspect it before use. Use it to reprogram the SPI chip with an external programmer, keeping a backup of the original. Verify the 18748-1 number and memory configuration on the PCB, and that the image size fits the chip.

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 →
