Help with Sapphire ATI HD 5570

[mostafagamal]

I tried to modify the framebuffer to enable multi-screen, but the information extracted with redsock decoder is not complete as I think !

Connector Object Id [12] which is [HDMI_TYPE_A]
	encoder obj id [0x21] which is [INTERNAL_UNIPHY2 (osx txmit 0x12 [duallink 0x2] enc 0x4)] linkb: false
Connector Object Id [2] which is [DVI_I]
	encoder obj id [0x20] which is [INTERNAL_UNIPHY1 (osx txmit 0x11 [duallink 0x1] enc 0x2)] linkb: false
Connector Object Id [2] which is [DVI_I]
	encoder obj id [0x15] which is [INTERNAL_KLDSCP_DAC1 (osx txmit 0x00 enc 0x10?)] linkb: false
Connector Object Id [5] which is [VGA]
	encoder obj id [0x16] which is [INTERNAL_KLDSCP_DAC2] linkb: false

 and when I try to change the framebuffer through Clover, the VGA is black after loading screen ! the attached file include the kext I currently use and the rom file, please help

You have to go this way from begin to end or wait if someone has exactly the same card and already did this.
