FT4STMS Ver 02HKT28A

BIOS .rar 2.72 MB Shared

BIOS file identified only as FT4STMS with version 02HKT28A, in a 2.72 MB rar archive. The name gives no brand, model or board number, so the target device must be identified by matching the version string to the firmware on the existing chip or the board markings. Images of this sort are written to the SPI flash with a programmer to recover a failed board. Always dump the original chip first and verify the image size equals the chip capacity before programming.

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.
