How to generate CLASSGUID and PCMCIA device ID to write in the INF file

Hi everybody,

Iam writing Win 2k PNP drivers for PCMCIA 16 bit PC card. In that
process, Iam trying to write .INF file, But I have two doubts in
preparing that file.
1. What is CLASS GUID. How it can be generated.I saw some examples
INF files in my system.In each file I observed "CLASS GUID".

What is the procedure to generate CLASS GUID?

2. "PCMCIA\Manufacturer-Product-NNNN"
NNNN is a four digit Hex code.
I can write Manufcaturer ID and Product ID.
But I was not able to create the four digit hex code.

I used DTPL.exe to generate PCMCIA unique device id.
I executed DTPL with our card CIS file as input.
But It is not generating the device ID and displays as ...

"Device ID cannot be created for the PC card"

What could be the reason? Is there any problem in the CIS
information or due to any other problem this message may come?

Please guide me in sovling the above problems.

Thank u,
Mahender.

Mahi,

The list of class INFs should be somewhere in the DDK documentation.
Just find other the INF of same device class in %windir%\INF and
copy to your INF. This is simplest and fastest.

Yes, DTPL can be used to generate the PnP ID.
If you run it correctly, with a proper CIS file *format* , the message means
that the CIS *data* is bad.

When you follow the simple procedure from my previous reply,
does "new device found" appear?
