Here's the Hercules Thriller 3D 8MB bios images.
The flash util included is easier to use than the Hercules one as it does not check the BIOS for a Hercules I.D.
Also, it can still flash the card bios if it has previously been incorrectly programmed with the wrong BIOS.
The following files are found inside the driver download file.
