为什么我的驱动程序安装不上??

我的系统是xp,我是用xpDDK中的build工具编译连接生成驱动程序simdriver.sys

我的sources文件如下:
TARGETNAME= simdriver
TARGETTYPE= DRIVER
DRIVERTYPE= WDM
TARGETPATH= sys
INCLUDES= inc
SOURCES= simdriver.c

我的inf文件如下:
[Version]
Signature="$Windows NT$"
Class=Unknown
CatalogFile.ntx86=simdriver.cat
DriverVer=03/05/2004

[SourceDisksNames.x86]
1="HiImWdm Free build directory",,,obj\i386\free

[SourceDisksFiles.x86]
simdriver.sys=1

[DestinationDirs]
DefaultDestDir=10,System32\Drivers

[Manufacturer]
%Sunshine%=sunshine

[sunshine]
%simdriver%= Simdriver_Inst,*Simdriver

[Simdriver_Inst.ntx86]
CopyFiles=SimdriverCopyFile
AddReg=SimdriverAddReg

[SimdriverCopyFile]
simdriver.sys,,,2

[SimdriverAddReg]
HKR,parament,0x12

[sunshine.ntx86.Services]
AddService=simdriver,0x00000002,simdriver_service

[simdriver_service]
DisplayName    = %mouclass_SvcDesc%
ServiceType    = 1
StartType      = 3
ErrorControl   = 1
ServiceBinary  = %12%\simdriver.sys

[Strings]
Floppy_Description="simdriver media"
Sunshine="x101.sunshine.net"
simdriver="Simply Driver"
mouclass_SvcDesc="simply driver"

不知道为什么,安装到最后总是提示"由于没有为设备范例指定函数驱动程序,安装没有成功"
但是,我发现simdriver.sys文件已经被copy到windows/system32/drivers中了

sys 和是否能安装成功关系不大，是不是编译过程中拷贝过去的？
