Hi,
I would like to study the pnpi8042 example in the ddk. I have built
i8042prt.sys. How can I install it?
Thanks in advance,
Ferenc
you can’t just copy it into %windir%\system32\drivers as I am guessing you found out. Furthermore, you can’t really use the add new hardware wizard or device manager to add your driver b/c you don’t want to write an INF.
To install your driver (and thereby bypassing the shipping i8042prt.sys, I would
1 change the sources file in the example to give the binary another name, say my8042.sys.
2 open hklm\system\currentcontrolset\services\i8042prt and change the ImagePath value from “System32\DRIVERS\i8042prt.sys” to “System32\DRIVERS\my8042.sys”
3 reboot
be careful here to either have a back up build or some other form of recovery since your driver will always be loaded during boot (assuming there are ps2 devices on your machine). If you do get stuck, goto your backup build and copy i8042prt.sys to my8042.sys to recover.

(also, please note that you are not supposed to ship an 8042 replacement. If you want to add 8042 added features, you should use a device upper filter driver (see kbdfiltr in the ddk)).
