Hi,

It worked! It takes 10 minutes to boot, but it gets speedy somewhere in the
booting process. I checked the memory speed with "stream" and its working.

Just for the record, I had to change the line in /etc/inittab
to "mtrr:345:once:/root/mtrrfixup.sh" or else, init would complain about the
first field being more than 4 characters.

Thank you very much

-- Diego
