I HAVE modified make.conf. Here is its contents: --- /etc/make.conf --- BATCH=yes NO_PROFILE=yes KERNCONF=DKA USE_FORTRAN=yes WITH_JADETEX=no PERL_VERSION=5.8.9 --- My custom kernel named DKA has only three modifications from GENERIC: I commented out the following three lines: #cpu I486_CPU #cpu I586_CPU #makeoptions DEBUG="-g" I have run with such a kernel on many machines for many years now. However, my experiments have shown that the kernel build is not to blame. Isn't boot part of the kernel build? Why would installing the kernel not cause this problem? It is by installing the world via make installworld that my drive gets munged. I obviously am missing something, but boot(8) sounds like it is in the neighborhood of where the problem is. There were changes to /usr/src/sys/boot/i386/libi386/biosdisk.c and biospnp.c that really look suspect to me. Dan
