BIOS image marked as a fix for the Toshiba Satellite L40D-B series, with board code CA10AN AB and the UMA variant, meaning integrated graphics only, on motherboard revision 2.1. Supplied as a 2.77 MB RAR archive. The name does not state the chip capacity, so check the flash size before programming. Read and save the existing chip first using an SPI programmer. Confirm the CA10AN marking and the 2.1 revision on the PCB, since a dedicated-GPU board needs different firmware.
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 @biosarchive. Enginerys does not host this file.
