Flash utility version?

[ratba_tardly]

I have an old Tyan Tomcat IV dual processor board that I would like to flash to a newer BIOS. I have the BIOS file, but the manufacturer's website doesn't specify which Award Flash utility to use for this board. There are at least three.
The question: WILL ANY AWARD FLASH UTILITY WORK FOR FLASHING AN AWARD 4.51PG BIOS?

If the flash utility isn't the correct one, will it damage the BIOS in anyway, or just halt?

Thanks,
Steve
