Install the RedHat kernel source RPM (no, not SRPM, there's an RPM of the kernel sources), then go to /usr/src/linux-version/configs and you'll find the configuration files used to compile the RedHat supplied kernel. There are several config files suitable for SMP/UP, BIGMEM, no BIGMEM etc etc., so just cp the right one as .config and there you go. > Another question: What patch do I have to apply in order to get the > encryption working?

Currently, when I perform the command "losetup -e aes-256 > /dev/loop0 .crypto" I get the error: "ioctl: LOOP_SET_STATUS: Invalid > argument".

Are you sure you need a patch and not just to enable support for that specific encryption scheme (AES) during "make menuconfig"? I wouldn't be surprised if RedHat came with the encryption options turned off because of American EAR regulations. Gilad -- Gilad Ben-Yossef <[EMAIL PROTECTED]> Codefidence.
