detect OS Version in WinNT4.0 for SCSI Miniport Driver

NTDEV
1

Hi all!

is there a way to detect the OS version (Including the service pack) under
windows NT4.0 for SCSI Miniport driver? the PsGetOsVersion() is documented
in win2K DDK. I could not find anything like PsGetOsVersion() in the NT4
DDK.
Any help would be appreciated!

Thank You

You can use PsGetVersion on Nt4.0. It’s exported.

Hi Eliyas and Zolee!

Thank you very much for your help. However, there is a comment
in the NTxDDK saying as follows:

“When the registry is initialized, a driver cannot obtain this
string from PsGetVersion, but must read the CmCSDVersionString
value from the registry.”

In our case We need to know if the OS has been installed with
Service Pack or not. How do we get the CmCSDVersionString from
the registry?

Thank you very much

You should try this registry key:

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\CSDVersion

Actually, you can find all the version info in HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion.
