GTX 260 显卡驱动 For Mac
本帖最后由 MemacX 于 2013-10-9 15:04 编辑附件是gfxutil工具和制作好的EFI_String及DSDT的范例
建立一个其他显卡的dsdt,然后把下面GTX260的代码替换过去,也可以把代码直接增加到PCI0节的下面.
DSDT 代码Device (PEGP)
{
Name (_ADR, 0x00010000)
Device (GFX0)
{
Name (_ADR, Zero)
Name (_SUN, One)
Method (_DSM, 4, NotSerialized)
{
Store (Package (0x16)
{
"@0,compatible",
Buffer (0x0B)
{
"NVDA,NVMac"
},
"@0,device_type",
Buffer (0x08)
{
"display"
},
"@0,name",
Buffer (0x0F)
{
"NVDA,Display-A"
},
"@1,compatible",
Buffer (0x0B)
{
"NVDA,NVMac"
},
"@1,device_type",
Buffer (0x08)
{
"display"
},
"@1,name",
Buffer (0x0F)
{
"NVDA,Display-B"
},
"NVCAP",
Buffer (0x18)
{
/* 0000 */ 0x05, 0x00, 0x00, 0x00, 0x00, 0x00, 0x03, 0x00,
/* 0008 */ 0x0C, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x0b,
/* 0010 */ 0x00, 0x00, 0x00, 0x00
},
"VRAM,totalsize",
Buffer (0x04)
{
0x00, 0x00, 0x00, 0x38
},
"device_type",
Buffer (0x0C)
{
"NVDA,Parent"
},
"model",
Buffer (0x17)
{
"NVIDIA GeForce GTX 260"
},
"rom-revision",
Buffer (0x5)
{
"3434"
}
}, Local0)
DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
Return (Local0)
}
}
}其中NVCAP和VRAM值是我的GTX260显卡的参数,你可以根据自己的显卡调整.
更新修改DSDT显卡位置：
DSDT里默认的显卡位置是PciRoot(0x1)/Pci(0x1,0x0)/Pci(0x0,0x0)，
但是一些显卡的位置可能不一样，虽然不影响显卡驱动（这个和efi-string不一样），
但是PCI卡那里的信息就没有了，因此可以修改硬件位置来解决这个问题，
假设用gfxutil得到的硬件位置是PciRoot(0x1)/Pci(0x3,0x0)/Pci(0x0,0x0)
PCI Device的第一节是Pci(0x3,0x0)，它的另一个形式是PciAdr(0x30000)，
我们来看PciAdr的定义
[*]PciAdr(uint32 adr) - alias for PCI node with using alternative address value.
[*]adr is PCI device "_ADR" property value that your may find from pci device properties in IOACPIPlane.
复制代码
因此，这里的_ADR就是0x30000，所以把
[*]Device (PEGP)
[*] {
[*] Name (_ADR, 0x00010000)
[*] Device (GFX0)
[*] {
[*] ...
复制代码
修改为
[*]Device (PEGP)
[*] {
[*] Name (_ADR, 0x00030000)
[*] Device (GFX0)
[*] {
[*] ...
即可解决这个问题
把编译好的DSDT放在mac分区的根目录或者Extra文件夹下,删除原来的ATY_init.kext,
重启,使用-v -f 启动,应该就能成功启动了

至此GT200系列显卡的EFI-String和DSDT驱动就说完了,这个方法在Snow Leopard一样适用,
现阶段开启Snow Leopard的64位内核的唯一方法就是使用Efi-String或DSDT来驱动显卡了
二楼是制作好的 变色龙配置文件com.apple.boot.plist
用文本编辑打开out.hex,里面就是做好的EFI-String了,
复制String到com.apple.boot.plist的device-properties下面,然后删掉ATY_init.kext,重启 -v -f应该就可以了
制作完成的com.apple.boot.plist应该是这个样子的
