There are seven predefined Operation Region types specified in ACPI:$ Y" Z' e& i9 X* h/ w6 V ?
0 SystemMemory
* d1 W) q+ G6 c5 q! c1 SystemIO ' R; W% j# z' l
2 PCI_Config . y- N, s5 [, X4 z9 B

5 CMOS , @: R) b8 Q- G# H# D5 i- c
6 PCIBARTarget
, o: d1 P! y1 G" D8 E为什么定义LID的状态端品为：
$ }% F5 P4 U4 A& B3 T& b. p6 ^9 pOperationRegion(\PHO, SystemIO, 0x201, 0x1)
4 n8 @; e5 D, G9 P- I! DField(\PHO, ByteAcc, NoLock, Preserve)

}5 Q8 p d% v; n" u- c6 C
3 @, A4 e }* B; C
IDE 0 and 1 的控制器却定义如下：: L P; S; {! d
OperationRegion (GIO, SystemIO, 0x125, 0x1)
# c3 G7 s9 @; p+ n Field (GIO, ByteAcc, NoLock, Preserve)
