GA-Z77X-UD5H - HD 4000 problem with dual monitor

[escobol]

Hi,

I got working mav instalation with "Bootloader and Extra to EFI Partition" from guide http://www.tonymacx86.com/401-install-bootloader-extra-efi-partition.html. Ive needed this partition because of AMD r280x.

Now i need to run my hackintosh without r280x (with only hd 4000). With one monitor everything is ok (monitor connected to DVI or HDMI works OOB).

Ive connect second monitor to free DVI or HDMI and got some problems.

1) When i connect second monitor to working mavericks (boot with one monitor to mavericks) everything is fine, it is recognized etc.

2) After mavericks restart with second monitor still attached i cannot boot to mavericks (i got chimera without gui - chameleon, like dos version (darwin?) when i choose OSX partition it boots and restarts within few seconds. (no flags, nothing helps, it looks like EFI partition is not working with second monitor? No chameleon? why?).

My attempts:

1) Changed SMBIOS on EFI Partition to MacPro3,1 (MacPro5,1 was for r280x) - no effect (dual - no boot, one monitor OK);
2) Changed org.chameleon.boot.plist (GE yes/no, IGPEnabler=Yes/No) - no effect (dual - no boot, one monitor OK);
3) Injected ig-platform-id (01660000/01660001) - no effect (dual - no boot, one monitor OK);

Any help? I got no more ideas what to check, what to do...
