Clover resolution ≠ Chameleon resolution

[chatzki]

Hi!

I've patched my GeForce 8400 GS VBIOS and substituted 1600x1200 resolution with 1600x1000. Everything worked with Chemeleon, I've had native 1600x1000 resolution during boot (max VESA resolution my card supports).

Things changed with UEFI bios and Clover. I now get 1600x1200 resolution again:

Why the hell it's doing it? Attaching debug.log. I've already tried CSM disabling. No decent how-to about VBIOS bytes patching found (Clover Wiki sucks in general, along with the bunch of features it definitely lacks documentation), I'll be grateful if anyone points me to it.

Ok, made it work by reinstalling Clover with all the drivers (CSM). Injected EDID. Set resolution to 1920x1200. Works!
