PCI Help please

I’m developing an WinNT PCI driver for a custom PCI board and I get stucked in HalAssignSlotResources call.
It always returns STATUS_CONFLICTING_ADDRESSES status. I tried with IoAssignResources
and similar problems occured (normally isn’t it?!). As I’m not very experinced with PCI bus
architectures, BIOS and so on, I would be gratefull if you can give some ideas about how PCI bus, BIOS and NT
works together. Who is in charge with allocating device resources (ports, I/O memory and intterupt) and
who can change them. And finaly, what should I do to replace HalAssignSlotResources or how (and where) can I find
the resources for my board.

References, books or web-sites documentation are also welcome.

Thanks,
Daniel

Hi, daniel,
First let me know the devices plug into u r system. and do one check
first, using PCIView tool u notedown all the devices base addresses OK.
and run WinMsd tool and check the resources place what are the devices
allready using the spaces, if any other device allredy using those
places u can verify that and remove that card and try it.

but generally the PCI bus case won’t give this type of problem.those
addresses will map dyanmically.

try this and give some more info… we will do our best.

bye

Hi Sunil ,

The card is pluged in and HalGetBusData returns following values for BARs:

Base Address 0 = 0x0008
Base Address 1= 0xD4400000

WinMsd returns:
Between 0x0000 - 0x000F is PC Compatible Eisa/Isa HAL (type=Internal) (but is another Bus isn’t it?)

but generally the PCI bus case won’t give this type of problem.those addresses will map dyanmically.

I also thought that way… but I really don’t know what’s happening.

Thanks, Daniel

From your information, BAR0 looks very bogus.

Hi ,

And maybe it is bogus, but who’s to blame for that? Is it hardware manufacturer? Is it NT?

Thank you,
Daniel

Hi Daniel,

Kindly check your device hardware manual / check with hardware people,
how they configured BAR 0 in the EEPROM.

According to your information

>Base Address 0 = 0x0008>>Base Address 1= 0xD4400000

totally looks impractical. Kindly let me know your machine
configuration. I mean size of the physical memory, no of pci device
sitting on the mother board etc etc…

Thanks!
Rgds,
Sunil.

Hi !

Thanx for your advices! My testing computer is:

  • AMD K623d-300MHz
  • Mother-board with sound card on board (but not installed on NT) and with a Via video-card on board too
  • Realtek NE 2000 compatible PCI network card
  • 64MB RAM

No of PCI devices is 3 (on board video card, network card and my device).

The PCI device is composed of:

  • Motorola Power PC 8240 processor (603e core at 200MHz, integrated PCI bridge)
  • 64 MB SDRAM
  • up to 2 MB Flash memory

I can chat with people from hardware dept. but I have to know exaclty what kind of questions to ask. As I
understood from you, the BAR values are read from PCI board’s EPROM? It would very appreciated any
advice from you regarding PCI bus configuration and programming since I’m new in this branch.

Daniel
