I recently came across this, a tool which can dump some PCI bus info from windows. This may be of use to people trying to put plan9 on systems that are already installed with windows.
perhaps this is old news and evryone knows about it, but I didn't. http://support.microsoft.com/kb/311272 example of usage: acroncompile1% devcon find pci\* PCI\VEN_10DE&DEV_0165&SUBSYS_029D10DE&REV_A1\4&14DB2FCF&0&0008: NVIDIA Quadro NVS 285 PCI\VEN_14E4&DEV_167B&SUBSYS_280C103C&REV_02\4&27454EAD&0&00E5: Broadcom NetXtreme Gigabit Ethernet PCI\VEN_8086&DEV_244E&SUBSYS_00000000&REV_E1\3&B1BFB68&0&F0 : Intel(R) 82801 PCI Bridge - 244E PCI\VEN_8086&DEV_277C&SUBSYS_00000000&REV_00\3&B1BFB68&0&00 : PCI standard host CPU bridge PCI\VEN_8086&DEV_277D&SUBSYS_00000000&REV_00\3&B1BFB68&0&08 : PCI standard PCI-to-PCI bridge PCI\VEN_8086&DEV_27B8&SUBSYS_00000000&REV_01\3&B1BFB68&0&F8 : Intel(R) 82801GB LPC Interface Controller - 27B8 PCI\VEN_8086&DEV_27C0&SUBSYS_280C103C&REV_01\3&B1BFB68&0&FA : Intel(R) 82801GB Serial ATA Storage Controllers - 27C0 PCI\VEN_8086&DEV_27C8&SUBSYS_280C103C&REV_01\3&B1BFB68&0&E8 : Intel(R) 82801GB USB Universal Host Controller - 27C8 PCI\VEN_8086&DEV_27C9&SUBSYS_280C103C&REV_01\3&B1BFB68&0&E9 : Intel(R) 82801GB USB Universal Host Controller - 27C9 PCI\VEN_8086&DEV_27CA&SUBSYS_280C103C&REV_01\3&B1BFB68&0&EA : Intel(R) 82801GB USB Universal Host Controller - 27CA PCI\VEN_8086&DEV_27CB&SUBSYS_280C103C&REV_01\3&B1BFB68&0&EB : Intel(R) 82801GB USB Universal Host Controller - 27CB PCI\VEN_8086&DEV_27CC&SUBSYS_280C103C&REV_01\3&B1BFB68&0&EF : Intel(R) 82801GB USB2 Enhanced Host Controller - 27CC PCI\VEN_8086&DEV_27D0&SUBSYS_00000000&REV_01\3&B1BFB68&0&E0 : Intel(R) 82801GB PCI Express Root Port - 27D0 PCI\VEN_8086&DEV_27D8&SUBSYS_280C103C&REV_01\3&B1BFB68&0&D8 : Microsoft UAA Bus Driver for High Definition Audio PCI\VEN_8086&DEV_27DF&SUBSYS_280C103C&REV_01\3&B1BFB68&0&F9 : Intel(R) 82801GB Ultra ATA Storage Controllers - 27DF PCI\VEN_8086&DEV_27E0&SUBSYS_00000000&REV_01\3&B1BFB68&0&E4 : Intel(R) 82801GB PCI Express Root Port - 27E0 PCI\VEN_8086&DEV_27E2&SUBSYS_00000000&REV_01\3&B1BFB68&0&E5 : Intel(R) 82801GB PCI Express Root Port - 27E2 -Steve
