Re: MVME5500 status, and on to PMC interrupts

Perhaps, it will help if you can describe your complete PMC system
configuration
with the module names and function Exactly which card is on the PMC1,
PMC2,
and PMC_SPAN ? I got bits of information from different E-mail you
posted.
I am still not positive about what the complete system configuration is.



MVME5500
  PMC1: ACROMAG PMC730 Multifunction Module
  PMC2: ACROMAG PMC341 Simultaneous Sampling Analog Input Module
  DEC 21150 PCI-PCI Bridge (PMCSPAN):
     PMC1: ACROMAG PMC730 Multifunction Module

Changed "bus<2" to bus<BusCountPCI() in pcifinddevice.c. The BusCountPCI calculation is wrong,
but I'm ignoring that for now since it is too big - I don't think that adds a problem.

Changed printout in BSP_PCIxFindDevice to include the pciNum passed in in pcifinddevice.c.

Changed pci.c to recognize the DEC 21150 PCI-PCI bridge.

During bootup I find the devices (see attachment)
PMC730-1: 0/0/6/0
PMC341:   1/0/6/0
PMC730-2: 0/2/2/0

XXX Look for "XXX" for my commentary.
