文本

HDAUDIO\FUNC_01&VEN_11D4&DEV_1981&SUBSYS_17AA2025&REV_1002
HDAUDIO\FUNC_02&VEN_14F1&DEV_2BFA&SUBSYS_17AA201B&REV_0900
PCI\VEN_1002&DEV_71D4&SUBSYS_20A417AA&REV_00
PCI\VEN_8086&DEV_109A&SUBSYS_200117AA&REV_00
PCI\VEN_8086&DEV_27DA&SUBSYS_200F17AA&REV_02
PCI\VEN_8086&DEV_4227&SUBSYS_10108086&REV_02

最后从&REV开始  都不要  

实现

HDAUDIO\FUNC_01&VEN_11D4&DEV_1981&SUBSYS_17AA2025
HDAUDIO\FUNC_02&VEN_14F1&DEV_2BFA&SUBSYS_17AA201B
PCI\VEN_1002&DEV_71D4&SUBSYS_20A417AA
PCI\VEN_8086&DEV_109A&SUBSYS_200117AA
PCI\VEN_8086&DEV_27DA&SUBSYS_200F17AA
PCI\VEN_8086&DEV_4227&SUBSYS_10108086
