HP Probook 4540s.....

[RehabMan]

I've tried with and without the option but nothing changed...

You are pressing F9 (for boot menu) at BIOS POST?

Make sure USB boot is enabled as well...

 

[Antholight]

Well... I don't know how but it does boot on usb. But annoying is not finished ! After I've launched the installer, I see the Apple logo and an animated circle for 30 seconds approx. The it disappears and let the screen black without any living sign...

Is that normal ? Nothing happens !

Try with "-x GraphicsEnabler=No"

Try with "-x GraphicsEnabler=No"

still done and tested. Nothing works.

Just to be sure... : on the flash drive, I juste have to format and partition it in MBR mode, launch unibeast on my iMac and that's all isn't it ? Then plug to my Probook and boot on it...

Does something miss me ?

Add "-v" to diagnose. Be sure you're typing it correctly. It is case sensitive and sensitive to spaces. It must be typed exactly (without quotes, obviously").

Also, I think some 4x40s users report having to use "PCIRootUID=0" (default is 1 for Unibeast).

I'm wondering what does this patch do on 4x40s with 1366x768 screen:

#   Inject HDMI info into GFX0/IGPU   */
into method label _DSM parent_adr 0x00020000 remove_entry;
into device name_adr 0x00020000 insert
begin
Method (_DSM, 4, NotSerialized)\n
{\n
    If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
    Return (Package()\n
    {\n
        "hda-gfx",\n 
        Buffer (0x0A) { "onboard-1" },\n
        "AAPL,snb-platform-id",\n
        Buffer (0x04) { 0x00, 0x00, 0x01, 0x00 },\n
        "AAPL,ig-platform-id",\n
        Buffer (0x04) { 0x03, 0x00, 0x66, 0x01 },\n
    })\n
}\n
end;

HDMI video works for me without adding that patch. I haven't tested audio, though.

In simple terms, it injects those properties into the io registry to be read by the driver. HDMI audio will not work without this "hda-gfx" property (and corresponding in HDEF). The others are related to selecting the snb-platform-id (HD3K) and ig-platform-id (HD4K) for the video driver.

Thank you!

RM, please add \n after Buffer (0x0A) { "onboard-1" } it's missing

#   Inject Audio info
into device label HDEF insert
begin
Method (_DSM, 4, NotSerialized)\n
{\n
    If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
    Return (Package()\n
    {\n
        "hda-gfx",\n
        Buffer (0x0A) { "onboard-1" },
        "layout-id",\n
        Buffer (0x04) { 0x0C, 0x00, 0x00, 0x00 },\n
        "PinConfigurations",\n
        Buffer (Zero) { }\n
    })\n
}
end;

Sure thing. Although it is not necessary...
