So I decided to move the DSDT injection over to a SSDT to go along with Clover Hotpatch. This is experimental although it works on my old Core 2 Quad System. In order to get this to work you're ATI 5450 will need to be under GFX0 instead of PEGP or IOPP. You will need Clover Bootloader for this to work. No need for (inject ATIi/True) in config.plist.

Old Guide. [Guide] Enabling ATI Radeon HD 5450

First thing you will need to do is rename PEGP to GFX0. Add patch under ACPI, DSDT, Patches use Xcode or a Plist editor not Clover Configurator as it will destroy the config.plist.

Code: 
Change PEGP to GFX0
Find <50454750>
Replace <47465830>

You will also need to add,
Code: 
Change _DSM to XDSM
Find <5f44534d>
Replace <5844534d>

Without Change _DSM to XDSM SSDT injection will not work neither will it work without Graphics coming under GFX0.

To Fix Graphics coming under IOPP add FixDisplay_0100/Yes to the config under ACPI, DSDT, Fixes.

Now for the SSDT Injection, Add to MacIASL as a template save it as SSDT-GFX0.aml. (Use Rehabmans version) RehabMan / OS-X-MaciASL-patchmatic / Downloads — Bitbucket

Code: 
DefinitionBlock ("", "SSDT", 2, "hack", "GFX0_HDA", 0x00000000)
{
    External (_SB_.PCI0.GFX0, DeviceObj)    // (from opcode)
    External (_SB_.PCI0.PEG0.GFX0, DeviceObj)    // (from opcode)
    External (GFX0, DeviceObj)    // (from opcode)

    Scope (_SB.PCI0.PEG0.GFX0)
    {
        Scope (GFX0)
        {
            Method (_DSM, 4, NotSerialized)  // _DSM: Device-Specific Method
            {
                If (LNot (Arg2))
                {
                    Return (Buffer (One)
                    {
                         0x03                                          
                    })
                }

                Return (Package ()

                })
            }
        }
    }
}

After following this guide your ATI 5450 should be working.

Problem reporting.

Post ioreg as ZIP: http://www.tonymacx86.com/audio/58368-guide-how-make-copy-ioreg.html. Please, use the IORegistryExplorer v2.1 attached to the post! DO NOT reply with an ioreg from any other version of IORegistryExplorer.app.

Also, press F4 at the main Clover screen, then compress and attach the EFI/CLOVER folder in use. And please, in order to reduce the size, omit EFI/Clover/themes.

You are using a DSDT. Just add ATY edits to DSDT. I wouldn't recommend using a DSDT with Clover Hotpatch. It's either one or the other.

Update : I was able to make the ATI Radeon HD 5450 work but the display is flickering from normal color to bluish color.
And the USB 3.0 still does not work.

ATI 5450 works fine with SSDT injection? Its experimental. USB 3 is off-topic.
 
Hi, I'm to the forum and to Hackintosh. I'm trying to get working my HD5450 under El Capitan on my older i3-550 based system. It's a custom motherboard from HP.
I tried faking the ID of the card and dumping and editing the DSDT, but I'm still stuck to an unidentified card.
From the DSDT, I saw that the card is under the P0P1 method, and there's no PEGP: how can I edit the file in order to patch the SSDT table?
