A lot of the improved debugging stuff goes back to the original i386 (according to my databooks). The only thing the Pent added was the ability to do breaks on IO-port accesses. I've got some test stuff that I threw into a ddb extension. It adds two ddb commands: `nm' to get at the symbol table; and `hbp' to get at the hardware debug stuff. Check the readme for more details. http://www.freebsd.org/~erich/ddb-patches.tgz It's not as nicely integrated with ddb as it could be, but it's functional. Luck, Eric -- Eric L.
