System: NetBSD samratchana 2.0F NetBSD 2.0F (SAMRATCHANA) #0: Mon Jul 5 07:51:06 UTC 2004 root@samratchana:/disk_i/src/src/sys/arch/i386/compile/SAMRATCHANA i386
Architecture: i386
Machine: i386
>Description:
	PCI mode detection fails so do pcbh probing leaving in onboard PCI
	devices and PCI addon cards in non working state.
	This was detected in m863-based motherboards by PC Chips
>How-To-Repeat:
	Boot m863-based i396 PC with stock kernel
>Fix:

	a) To force PCI mode to pci_mode1 (for this machine)
	b) Add the pci_bridge rev into the database so the probe works
