BIOS ROM image for a Toshiba Satellite L300D-03K laptop, with model number PSLC8C-03K01R given in the name. The uncompressed 1 MB file matches an 8 Mbit SPI flash chip, which should be confirmed on the board before programming. No mainboard number is stated, so read the PCB silkscreen to identify the board. The .rom can be opened directly by programmer software such as CH341A tools or RT809H. Save the existing chip contents first and verify the data after writing.
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.
