Have a look at the kernel code: (I'm referring to kernel 2.2.3 but it may be exactly the same for 2.0.34 for this particular feature.) See arch/i386/kernel/traps.c I don't know what it means, but there are two "F0 0F"'s mentioned in that file. And a function called trap_init_f00f_bug(void) In arch/i386/kernel/setup.c there is also a mention of "f00f" It looks like there is a C variable called "f00f_bug" I suggest you view these files with "vim" as it will colorize the syntax and make it easier to read. :) Besides, vim is maintained by our fearless leader: Wichert Akkerman, Debian Project Leader! :^) --Brock Lynn --------------------- PGP 43 3C 3B CB CE 4B BF D3 F4 59 BD 97 92 DB 48 9C __ _ Debian GNU R.
