Hello everybody
I’m writing a driver for Windows NT and wants to insert above ‘Disk Driver’
and I hav make the Registry entry for the ‘service’ but I’m not getting
where to make the entry in ‘Registry’ for loading the driver, So if anyone
of you can tell me about this, it would be very helpful.
Thanks.
Anuj Agarwal
Study diskperf code and registry values, you will get the stuff you need.
If you are intending to implement a class upper filter driver you need to
add your driver to the UpperFilters entry for the disk class. See the
diskperf sample in the ddk.

Mark,
Anuj is asking about WinNT4, and there is no disk class registry entry on NT4, that’s the problem.
(I mean the … 967… one, on NT4SP6A “Class” starts from …968…, as in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4D36E968-E325-11CE-BFC1-08002BE10318}
which is “Display Adadpters”)
Looks like you have to do it manually…
Regards,
Alex Shvedov

Actually the same general advice applies: see the diskperf example, only
this would be the NT4DDK diskperf.

Thanks EveryOne.
Alex you are exactly right that there is no registry entry for disk class
and I also made the manual entry but its not working.
Actually I made the entry in class {71A27CDD-812A-11D0-BEC7-08002BE2092F}
for Win-2K for the same type of driver and made the entry fr UpperFilters
and it worked perfectly there but on NT its not working, all services are
working good enough but driver is not working so can you please tell me what
exactly can be the problem and which class is similar to the one in 2K.
Thanks.

Anuj,
I really like Mark’s last advice: no such class? ok, look into DDK, but this time into the NT4 DDK.
which class is similar to the one in 2K
No such thing as “similar”.
The whole mechanics in NT4 case is different: you have to do it MANUALLY.
Dust off your NT4 DDK CD circa 1999 AD and check diskperf.c, you may want to look at
VOID
DiskPerfInitialize(
IN PDRIVER_OBJECT DriverObject,
IN PVOID NextDisk,
IN ULONG Count
)
/*++
Routine Description:
Attach to new disk devices and partitions.
Set up device objects for counts and times.
If this is the first time this routine is called,
then register with the IO system to be called
after all other disk device drivers have initiated.
Do you see this? They have to do the dirty part themselves this time.
Regards,
Alex Shvedov
