Hi guys and experts
I noticed the "original Sapphire" BIOS files for 6950 and 6970 are not that much different, binary-wise:
(differences are highlighted in red on the left)
So of the 128 KiB BIOS way more than 95% are exactly the same.
The differences on top are mainly ID-strings.
Also there has to be the shader-unlocking-trick as a visible difference somewhere.
Leaving us with the rest:
The diffs in the middle look to my unsuspecting eye like lookup-tables, leaving only few differences in code-blocks, if at all.
Now my question to the bitpushers: what exactly *are* the differences between the BIOSes? Are the RAM parameters (voltage/timings) stored in here? Can they be read and analyzed to know the exact values?
