PCI Error Code Format
  Error codes are displayed on the screen as eight or sixteen digits:
DDDD DD S 0 VVVV IIII
|-----| | | |--| |--| 
   |    | |   |    |-- PCI Device ID
   |    | |   |------- PCI Vendor Number 
   |    | |----------- Reserved (usually 0)
   |    |------------- PCI Slot Number (0= System board)
   |------------------ PCI Device Error

 For example, PCI error code 005A0210VVVIIII decodes: 

Digit(s)	Information
005A 02	PCI device disabled due to Built-in Self Test failure.
1	The device is in PCI slot number one.
0	Reserved.
vvvv	Could be any number (PCI vendor ID).
iiii	Could be any number (PCI device ID).

PCI ErrorMessages

Error Message	FRU/Action
PCI device(s) removed since last power up: PCI vendor ID=xxxx,  device ID=xxxx  previously in slot x	1. One or more PCI add-in devices appear(s) to have been removed since the last execution of POST. This could be due to a catastrophic failure of the PCI device rather than its actual physical removal.
PCI device(s) added since last power up: PCI vendorID=xxxx, deviceID=xxxx in slot x	1. One or more PCI add-in devices has been added since the last execution of POST. It may have been moved from another slot. Thisis not an error. The device was enabled and had resources assigned.
Unable to assign requested resources: PCI vendor ID=xxxx device ID=xxxx in slot x Block	1. A requested PCI resource (from the PCI Device Configuration) could not be assigned as requested due to a conflict with a non-PCI deviceor to a conflict with another requested PCI resource.
