Hi all, I am developing OX16PCI954(4 channel PCI Serial Device). Now, Only ONE channel is attached. Because, Only ONE [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\PCI\Instance\OX16PCI9541] is created. So, I tried to create FOUR INSTANCE as the following. [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\PCI\Template\OX16PCI954_1] "DeviceArrayIndex"=dword:0 "Dll"="OX16PCI954.dll" "Class"=dword:07 "SubClass"=dword:00 "ProgIF"=dword:06 "VendorID"=multi_sz:"1415" "DeviceID"=multi_sz:"9501" "Prefix"="COM" "IsrDll"="giisr.dll" "IsrHandler"="ISRHandler" [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\PCI\Template\OX16PCI954_2] "DeviceArrayIndex"=dword:1 "Dll"="OX16PCI954.dll" "Class"=dword:07 "SubClass"=dword:00 "ProgIF"=dword:06 "VendorID"=multi_sz:"1415" "DeviceID"=multi_sz:"9501" "Prefix"="COM" "IsrDll"="giisr.dll" "IsrHandler"="ISRHandler" [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\PCI\Template\OX16PCI954_3] "DeviceArrayIndex"=dword:2 "Dll"="OX16PCI954.dll" "Class"=dword:07 "SubClass"=dword:00 "ProgIF"=dword:06 "VendorID"=multi_sz:"1415" "DeviceID"=multi_sz:"9501" "Prefix"="COM" "IsrDll"="giisr.dll" "IsrHandler"="ISRHandler" [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\PCI\Template\OX16PCI954_4] "DeviceArrayIndex"=dword:3 "Dll"="OX16PCI954.dll" "Class"=dword:07 "SubClass"=dword:00 "ProgIF"=dword:06 "VendorID"=multi_sz:"1415" "DeviceID"=multi_sz:"9501" "Prefix"="COM" "IsrDll"="giisr.dll" "IsrHandler"="ISRHandler" But, the result is that only one instance is created. Q) How can I create four instance as one device driver?

Because the OX16PCI954 only have ONE device function on the PCI bus. So the PCI Bus driver (pcibus.dll) always think that there is only one device function, so it alway initail one instance!! My suggestion is instead of activating the OX16PCI954.dll directly, you could write a pre-loader dirver. The pre-laoder driver is setting in template registry and activated by the pcibus.dll then the pre-loader will do the real job to activate the OX16PCI954.dll. you may refer to the ATAPI driver that using such kind of skill.
