2006-12-09 Thread John Richard Moser
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Apparently (as I've been told today) using a hardware NX bit in a 32-bit x86 kernel requires PAE mode. PAE mode is enabled with HIGHMEM64, which is (apparently) extremely slow. Is it possible to give some other way to get the hardware NX bit working
