Ah, if you have a working machine where you can build a kernel, you can build an new CD using an existing ISO as a template. Simply build a GENERIC kernel and install it into some DESTDIR=/foo and mount the ISO image using mdconfig to /dist. Then do something like 'mkisofs -o new.iso -r -J -b boot/cdboot -no-emul-boot -x /dist/boot/kernel /dist /foo'. If that complains about duplicate 'boot/kernel' then you may need to copy all of /dist/boot to /foo/boot, install the new kernel into /foo, and use '-x /dist/boot /dist /foo'. Also, if this machine supports PXE boot at all, that can be a way to boot a test kernel as well. -- John Baldwin
