HCL H54Y UMA HM55 PCH

BIOS .bin 4.00 MB Shared

BIOS image for an HCL laptop built on the H54Y board, labelled UMA, meaning integrated graphics only with no discrete GPU, and tied to the Intel HM55 platform controller hub. The 4.00 MB raw binary matches a 32 Mbit SPI flash chip, so it can be written directly with a programmer such as a CH341A or RT809. Read and save the original chip contents first, and confirm the board marking and UMA configuration match before flashing, since a discrete-graphics variant may need a different image.
