Hi,
Thank u Mr.Pavel for giving such a valuable suggestion. With ur
Reply Iam Proceeding to develop pnp drivers for our pcmcia 16 bit pc
card.
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. 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.
Please guide me in sovling the above problems.
Thank u,
Mahender.
