Working BIOS for the Sony VAIO board MBX-238 marked S0201-2, with dumps for both U35 and U36, indicating two separate flash chips on this board. The 4.98 MB RAR is described as fully working. Sony uses the MBX numbering for its notebook mainboards. Write each image only to its matching chip position with an SPI programmer, read and save the original contents of both first, and check that the board code on the PCB agrees before flashing.
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.
