Modified BIOS for the Dell board LA-L946P, described as fixing SSD and TPM issues and marked as fully working. LA numbers follow the Compal scheme, the ODM behind many Dell mainboards. The rar archive is about 10.4 MB and should contain an image for direct SPI programming. Such a fix is often used when a board stops detecting storage or reports TPM errors. Check that the LA-L946P number on the PCB matches, confirm the chip size, and dump and keep the original firmware before writing this version.
