Hi,
I’m writing a WIN-NT device driver for parallel port. Right now I’m trying
with the supplied examples with DDK tool kit (ParPort & Parclass). After
building these two drivers I have installed it in new M/C & set all the
registry entries. But at the time of booting the M/C, it is giving the error
i.e. “The \systemRoot\system32\Drivers\Parport.sys device driver could not
locate the entry point IoRegister Device interface in driver ntoskrnl.exe”.
Can you suggest me how can I do this. Actually I want to develop this driver
to communicate two PCs with Parallel Port.
The other problem is After building these two driver it is generating the
files Parport.sys & parallel.sys & these driver already exist in WIN-NT.
Please suggest me whether we can use these two sample driver as a base of my
new driver. If yes, then how can we add our IO controls into that…
Waiting for early reply.

After using dumpbin to look at what ntoskrnl exports in NT and Win 2K, I saw
that IoRegisterDeviceInterface is a Win 2K function, apparently not
supported on Win NT. Try installing your drivers on Win 2K. If drivers of
the same name already exist on Win 2K, you’ll have to disable system file
protection to install them, unless you rename the files.
