The Hawaii Bios Reader tool is for developing Bios.
Before working with the utility, make a backup copy of the original BIOS on the video card for each switch position.
Edit copies of the original BIOS so that you always have the original unedited BIOS that you can use if something goes wrong.
You don’t need to flash two BIOS positions at once, in this case you can boot from the other one if something goes wrong.
After you have changed the BIOS, make a copy of it and after correcting the checksum on one of them using the HawaiiReader utility. Compare the 2 copies using the compare function in the hex editor to find out only the checksum that changed before flashing.
