Detection of cardbus card.!

Hi All,

I need a small doubt to be clarified regarding the Cardbus card detection
on Windows-2000. As i have searched some of the sites where it says
Windows-98 can not enumerate the Cardbus cards. So for these
they(Micorsoft) have released the patch(Microsoft knowledge base
article:-Q233017). So is there some thing similar on windows-2000 also for
TI-1410 Chip(as a bridge between PCI-Cardbus).But when we try to insert
some standard cardbus cards into the TI-1410 Bridge these are detecting
and working properly. But when we insert our card, it just detects as a
32-bit card, but it is switching off the power before it displays that
there is a new hardware found. Even we are not able to see that there is
some new hardware is plugged in. So could any one can clarify us this
issue.
one more thing is that i wanted to know whether windows-2000 detects the
PCI Devices by polling method or by some interrupt mechanism for each
slot?
Hope i will get some guidance on these issues.

Thanks & Regards,
