BIOS archive for the PLACC / CSAC board family, UMA integrated-graphics version, revision 2_1 according to the name; no brand or model is stated. The RAR is 1.43 MB. Make sure your board uses integrated graphics and the revision printed on the PCB agrees, since UMA and discrete images are not interchangeable. Flash with an SPI programmer after reading and keeping a copy of the existing chip, and verify the extracted image size equals the chip capacity before you write.
