Hi list How can I do so? By hardware informations I mean which card is located on which slot, card serial number, manufacturer and ... . I know some utils do this e.g. dmesg, pciconf but I want to write something on my own. Any suggestion is appreciated.

Why don't you read the source for pciconf? If you installed the source, it's availabe in /usr/src/usr.sbin/pciconf? Or you can read it on the web at: https://svnweb.freebsd.org/base/head/usr.sbin/pciconf/ -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
