ATI Radeon HD 6750 Mac驱动 DSDT驱动方法
HD6750，不用刷BIOS，直接将原来的device-id 68BF改成ML里面能直驱的68B8，加入到DSDT，其他的马甲显卡可以参考；
"device-id", Buffer (0x04)
{
0xB8, 0x68, 0x00, 0x00
},
加在PEG0下DSDT完整代码如下，以下代码仅供参考，请根据你的实际卡的情况修改
Device (PEG0)
{
Name (_ADR, 0x00010000)
Method (_PRT, 0, NotSerialized)
{
If (PICM)
{
Return (AR02 ())
}
Return (PR02 ())
}
Device (PEGP)
{
Name (_ADR, 0xFFFF)
Name (_SUN, One)
Method (_DSM, 4, NotSerialized)
{
Store (Package (0x0C)
{
"@0,name",
Buffer (0x0D)
{
"ATY,Pithecia"
},
"@1,name",
Buffer (0x0D)
{
"ATY,Pithecia"
},
"@2,name",
Buffer (0x0D)
{
"ATY,Pithecia"
},
"device-id",
Buffer (0x04)
{
0xB8, 0x68, 0x00, 0x00
},
"model",
Buffer (0x13)
{
"AMD Radeon HD 6750"
},
"hda-gfx",
Buffer (0x0A)
{
"onboard-1"
}
}, Local0)
DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
Return (Local0)
}
Device (HDAU)
{
Name (_ADR, One)
Method (_DSM, 4, NotSerialized)
{
Store (Package (0x02)
{
"hda-gfx",
Buffer (0x0A)
{
"onboard-1"
}
}, Local0)
DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
Return (Local0)
}
}
}
}
ATI Radeon HD6750 实际就是ATI Radeon 5770 的马甲卡比ATI Radeon 5770流处理器少点，核心完全一样。
