Yes, I have found the patches for linux kernel here;
http://www.ussg.iu.edu/hypermail/lin...03.3/0362.html
ftp.kernel.org/pub/linux/kernel/people/axboe/
I will try to read more carefully.

In regard to Mt.Rainier, I did download demo version WriteCD-RW! from;
http://www.softarch.com/index.html
It didn' work due to unsupported drive error for Mt.Rainier even though the drive's property says it supports.
I just gave up

I must learn more and more, thanks for the input!
