Microsoft Surface PRO 7 1866 JALAMA ICL MB 2.0B 16MB BIOS

BIOS .rar 4.68 MB Shared

BIOS archive for the Microsoft Surface Pro 7, model 1866, with the board identified as JALAMA on an ICL (Ice Lake) platform, motherboard revision 2.0B. It contains a 16MB flash image packed in a 4.68 MB RAR. Surface boards are compact and the SPI chip is small, so reflashing usually needs careful clip work or removal of the chip for an external programmer. Confirm the board revision matches yours. Read and keep the original chip contents, since device-specific data may be lost otherwise.
