    Description

      AGP to PCI bridge has uninitialized data in the PCI BAR registers, so the pci.sys driver is not able to enumerate its children (which is the Xbox GPU device).

      (drivers/bus/pci/pdo.c:777) Device 10de:01b7 (class 0x06) at 0:30:0 is a bridge
      		 
      (drivers/bus/pci/pdo.c:955) Device 10de:01b7 (class 0x06) at 0:30:0 is a bridge -> setting bus number #1/#1
      		 
      (hal/halx86/legacy/bus/sysbus.c:109) Translation of bcfaf7e4 failed!
      		 
      (ntoskrnl/io/pnpmgr/pnpres.c:1017) Failed to translate port resource (Start: 0xbcfaf7e4)
      		 
      (ntoskrnl/io/pnpmgr/pnpres.c:1179) Failed to translate resources for PCI\VEN_10DE&DEV_01B7&SUBSYS_F8BFEF87&REV_A1\2&b3ac4ede&1E

      It's not a major issue, since we're able to get video output anyway.

      This happens only on real hardware Xbox. On the emulator these BAR registers are zeroed out.
