Minimal DSDT Edits for Gigabyte Socket 1366 Motherboards

Since I posted Minimal DSDT Edits for Gigabyte Socket 1156 Motherboards I picked up a Gigabyte X58A-UD3R Rev 2.0 motherboard as part of the post tonymacx86 and I did for the CustoMac Pro 2010 project on his blog.

I started researching and testing what edits from my Socket 1156 post were or weren't needed on this board. The good news is that the majority of the edits carry over, but some are not needed. For example, we don't need to inject anything for the USB ports to be fully recognized. But there are a couple of required Socket 1366 specific edits.

The following is a guide for editing the extracted DSDT from the new Hackintosh-friendly BIOSes only. If you don't have a new Hackintosh-friendly BIOS, as I described in a previous post, you will have to have to manually edit the DSDT for the CMOS reset issue. You will also need to do the three required edits needed regardless of BIOS version. They are to include Method DTGP, add Return Package at the end of _WAK and fix the "Method local variable is not initialized (Local0)" error.

Now let’s review the common edits that are valid for the Socket 1356 and Socket 1156 motherboards.

First up are the cosmetic changes. Gigabyte uses generic device names in its DSDT instead of descriptive names like Apple does. One example is Gigabyte uses PX40 instead of LPCB for the LPC Interface Bridge. So the first thing we can do is to search for PX40 and do a global replace with LPCB. The next is to rename the System Management Bus (SMBus) device PX43 to SBUS. Next would be to rename Device (IDE1) to Device (SATA) and then within it rename Device (PRIM) to Device (PRT0) and Device (SECD) to Device (PRT1). The final cosmetic edits deal with USB. You can rename the devices to more appropriate ones as shown within this list:

Rename USB0 to UHC1
Rename USB1 to UHC2
Rename USB2 to UHC3
Rename USB3 to UHC4
Rename USB4 to UHC5
Rename USB5 to UHC6
Rename USBE to EHC1
Rename USE2 to EHC2

Next we need to add to Device (SBUS) a sub-device named Device (BUS0) as seen here:

                Device (BUS0)
                {
                    Name (_CID, "smbus")
                    Name (_ADR, 0x00)
                    Device (DVL0)
                    {
                        Name (_ADR, 0x57)
                        Name (_CID, "diagsvault")
                        Method (_DSM, 4, NotSerialized)
                        {
                            Store (Package (0x02)
                                  {
                                    "address",
                                     0x57
                                  }, Local0)
                            DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                            Return (Local0)
                        }
                    }
                }

The next edit is for audio. Gigabyte uses a device name of AZAL, so we need to do a global replace with HDEF. Then we need to add codec information to Device (HDEF). All that is required is to inject layout-id and PinConfigurations.

Here is an example of what needs to be added for a board using an ALC889 codec and using our Legacy889HDA.kext:

                Method (_DSM, 4, NotSerialized)
                {
                    Store (Package (0x04)
                        {
                            "layout-id",
                            Buffer (0x04)
                            {
                                0x79, 0x03, 0x00, 0x00
                            },
                            "PinConfigurations",
                            Buffer (Zero)
                            {
                            }
                        }, Local0)
                    DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                    Return (Local0)
                }

There is a problem with Audio break ups in 10.6.3 and later that can be corrected in the DSDT. The first is in Device (PIC) remove these two lines:

                IRQNoFlags ()
                {2}

The other fix for audio break ups is in Device (TMR) where Gigabyte has not yet added Hackintosh logic. We need to change:

                    Method (_CRS, 0, NotSerialized)
                    {
                        If (LGreaterEqual (OSFX, 0x03))
                        {
                            If (HPTF)
                            {
                                Return (ATT6)
                            }
                            Else
                            {
                                Return (ATT5)
                            }
                        }
                        Else
                        {
                            Return (ATT5)
                        }
                    }

To:
                    Method (_CRS, 0, NotSerialized)
                    {
                        Return (ATT6)
                    }

Gigabyte has not yet added Hackintosh logic to Device (HPET), so you will get kernel panics in AppleIntelCPUPowerManagement. The fix is easy; just change Method (_STA, 0, NotSerialized) to Return (0x0F) and to change Method (_CRS, 0, NotSerialized) to Return (ATT3).

The next edit allows use of the power button to put the computer to sleep.  In Device (PWRB) change Name (_HID, EisaId ("PNP0C0C")) to Name (_CID, EisaId ("PNP0C0C")).

One fix we can do in a Socket 1366 DSDT that I haven't been able to figure out how to do in a Socket 1156 DSDT, is cure the orange external drive icon issue. In Device (SATA) you need to add the following code:

                Method (_DSM, 4, NotSerialized)
                {
                    Store (Package (0x02)
                        {
                            "device-id",
                            Buffer (0x04)
                            {
                                0x81, 0x26, 0x00, 0x00
                            }
                        }, Local0)
                    DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                    Return (Local0)
                }

For the final edits, we can thank insanelymac user mm67. His modification enables shutdown without a kernel panic (KP). This is a two part edit, of which for the first part after:

    OperationRegion (APMP, SystemIO, 0xB2, 0x02)
    Field (APMP, ByteAcc, NoLock, Preserve)
    {
        APMC,   8,
        APMD,   8
    }

Insert:

    OperationRegion (PMRS, SystemIO, 0x0430, 0x01)
    Field (PMRS, ByteAcc, NoLock, Preserve)
    {
        , 4,
        SLPE, 1
    }

For the second part change:

    Method (\_PTS, 1, NotSerialized)
    {
        Or (Arg0, 0xF0, Local0)
        Store (Local0, DBG1)
        OSTP ()
        If (LEqual (Arg0, 0x01)) {}
        If (LEqual (Arg0, 0x03)) {}
        If (LEqual (Arg0, 0x05))
        {
            Store (0x99, SMIP)
        }

To:

    Method (\_PTS, 1, NotSerialized)
    {
        Or (Arg0, 0xF0, Local0)
        Store (Local0, DBG1)
        OSTP ()
        If (LEqual (Arg0, 0x01)) {}
        If (LEqual (Arg0, 0x03)) {}
        If (LEqual (Arg0, 0x05))
        {
            Store (0x99, SMIP)
            Store (0x00, SLPE)
            Sleep (0x10)
        }

So with these edits you'll have a fully functional Socket 1366 DSDT for Gigabyte motherboards. If you don't want to tackle these edits yourself, we maintain a database at tonymacx86 with all of these edits already applied. You will always find the latest versions listed here and can access the complete database here.

If you don't see your Gigabyte Socket 1156 or Socket 1366 motherboard or version listed. You can submit it on the tonymacx86 Forum by clicking here. The instructions are at the top of the topic. After we receive it and verify that it is vanilla, we will do the edits and upload it to the database.
