whoa..hey!
back up a second.
there's two things you have mentioned here that I've been seeking
for some time.
Please, expend on the following:
use of 'noprobe' for /dev/hdc in LILO.
autotune? What is this and where do I find more about it?
Are these 2.2.18 features?
Is it all in some lilo doc that I haven't found yet?
