[Guide] Enabling ATI Radeon HD 5450

[VioletDragon]

I looked at config, and set loadvbios=true, patchvbios=true, port=3. And now I have black screen, when I choose boot from ...
Yes I always had injectati=true.
And, when I try to start BIOS, I had password. Can it be after DSDT install?

To remove BIOS Password reset you're CMOS with the jumper on the board. You do not need Load VBIOS, Patch VBIOS.

You can do it at Clover, Options, (Graphics Injection).

In clover's options when I switch off load vbios, no changes - black screen. I don't know how to switch off patch vbios((
Thank very much for your help.
