Re: [NTDEV] Legacy drivers, 2000, and a Compact PCI

Greg,

The driver is an NT4 free build that works under NT4 and 2000, on all
hardware platforms that we have tested it on except cPCI. The report from
the customer is that it also works under NT4 on the cPCI platform.

The main issue with cPCI is that you usually have an
additional PCI-PCI
bridge before your cPCI bus devices. The PMC will usually
add an additional
bridge. If your device or driver is sensitive to the
additional bridging
(and I don’t recall all of the ramifications) this may be
part of your
problem. I understand that the device and driver functioned
normally under
NT4, but was that on a cPCI system with NT4? There may be
some issues with
W2K regarding the additional bridge programming/mapping that
exposes the
sensitivities in your device. This is just a guess. The
only cPCI driver
work I have done is under Windows CE, not NT/W2K.
