I've been playing a bit with listdev, it seems it uses a driver to list the ISA and PCI config: [revol@patrick /boot/home/devel]$ strings /bin/listdev|grep '/dev' /dev/misc/config I think it's used by the Devices preferences panel also... [revol@patrick /boot/home/devel]$ strings /boot/preferences/Devices |grep /dev /dev/misc/config Anyone of the preferences team begun hacking on it ? Maybe it will be better first to have a listdev clone, then making the gui version. I grepped the Be headers, but didn't find anything about the IOCTLs for this device. Anyone has some infos ? I'll try to search google and bedriven maybe. Also, I have a PCI id list in my bookmark: http://www.yourvote.com/pci/pciread.asp?sort=venid Anyone has a larger/better one ? I think we should have something like /etc/pci_ids, which would store this database, so it would be easier updating it (a shell script using wget and sed), than hving to recompile both listdev and Devices, since both uses the same database.
