Pci.sys resource configuration conflicts cause an error in Windows Server 2003 SP1 or in an x64-based version of Windows Server 2003: "Stop 0x0000007B"

On a computer that is running Microsoft Windows Server 2003 Service Pack 1 (SP1) or an x64-based version of Microsoft Windows Server 2003, you experience one of the following symptoms:

• The computer stops responding during startup.
• An error that resembles the following is generated in the Pci.sys process:
  Stop 0x0000007B (parameter1, parameter2, parameter3, parameter4)
  INACCESSIBLE_BOOT_DEVICE
  Note The parameter values may vary.
  
  This Stop error may occur only when a PCI device is used in a specific PCI slot.

This problem may occur if one of the following conditions is true:

• You try to upgrade an original release version of Windows Server 2003 to Windows Server 2003 SP1 when a PCI adapter is present in slot 4 or slot 5.
• You try to perform a new installation of Windows Server 2003 SP1 or an x64-based version of Windows Server 2003 on an IBM x236-based server that has a PCI adapter in slot 4 or slot 5 or both slots.
• You install a new PCI adapter in slot 4 or slot 5 or both slots on a computer that is running Windows Server 2003 SP1 or an x64-based version of Windows Server 2003.

This problem occurs because of an I/O resource conflict that can occur in certain hardware configurations of Windows Server 2003 SP1 or an x64-based version of Windows Server 2003. This conflict can prevent certain PCI devices that are located behind a PCI bridge from being configured correctly. This problem can cause the computer to stop responding or not start because of an inaccessible boot device.

Note This problem does not occur on a computer that is running the original release version of Windows Server 2003.

Currently, this problem is known to occur on the following computer system:

• IBM xSeries 236
