pull compile config out of running kernel


is there anyway to find out what options a running kernel was compiled with?

i have a unknown manufacturer server box that runs fine w/ an existing linux system. the kernel wasn't compiled on this box. i want to build up a new system from scratch on this box, but i'm not sure what drivers etc i'll need. instead of watching the boot up and making lots of notes, is there any way i can pull the info out of the kernel itself? i'm looking to create a .config for the existing kernel from the kernel binary itself.

thanks in advance.

look in /proc if there is a file called config.gz then you can "zcat /proc/config.gz > filename" to get the compile options. Or (derending on your setup) it may be in /boot/config-(kernel-version) eg config-2.6.15-25-686
