PCH BIOS image for the Dell Vostro 3450, taken from a Quanta-designed board marked DAV02AMB, with a status note that it works. The file has no extension, but at 4.00 MB it is a raw image for the main SPI flash of the Intel platform controller hub. Quanta uses DA-prefixed board codes printed on the PCB, so compare that marking before writing. Keep a backup of the existing chip, then program the dump with a CH341A or similar tool. The garbled characters in the name come from a broken text encoding.
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_laptop. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
