Please develop for legacy BIOS Windows 10

[jumpnkick]

MBPs older than 2012, need to install W10 in legacy BIOS mode (installed through DVD only).
Most of them have dedicated GPU broken (known issue).
W10 runs great, but cannot get integrated drivers to work.
Would be a great fix for us.
Thanks for any help.

That's sadly not possible I think, you'll need to use EFI.

And to customize resolution on Microsoft Basic Display adapter?
At least to have it to 1920x1200 native?
I found this: https://ywjheart.wordpress.com/2014/04/19/modify-microsoft-basic-display-driver-to-get-a-better-resolution/ though I don't know how to edit sys file myself, and the resolutions this person patched, are not 1920x1200.
If somebody can help it would be awsome!
