ATI 38xx BIOS editor (Finally!)

[SRV]

Well, all I can say is, the Bios editor app does a checksum correction at the end, and the checksum on original and new files are the same (7500)

Basicaly, a checksum is a hex value that is used to verify the validity of a file. If you change content of a file (in this case the voltage values inside the bios file), the checksum of a new file will be different from the original. So now, you have to modify unneeded information in the file to make checksum equal. Most people change the text from the warning message built in to the bios that instructs you to plug in your power cable to accomplish this.

I hope that makes sense, I did my best to try to explain

Oh, now I see. Thanks for explanation.

EDIT: Sorry if I am boring , is it perfectly safe if I apply this HIS bios on reference 3850 card? Memory is afaik Samsung 1.1ns. Does this match? And I don't know what PCB design that HIS card has, is it also reference? Thanks in advance!
